EMTP FALL USER CONFERENCE was held in Paris, 30-31st August, 2022, during the „CIGRE Paris Session 2022“.
It was a great oportunity to exchange experiences and views for further development of EMTP software and to initiate new collaborations. At this conference, a presentation with title „Analysis of transient recovery voltage on circuit-breaker connected to HV terminals of step-up transformer located in hydro power plant“ was held, whose authors are from FER - Department of Energy and Power Systems: Božidar Filipović-Grčić, Nina Stipetić and Franjo Vuković.
The international conference „CIGRE Session 2022“ was held in Pariz from the 28th of August to the 2nd of September, the largest symposium organized every two years by CIGRE. Because of the pandemic, the conference was not held in 2020, so a record number of power system experts from all around the world participated this year. Employees of the Department of power systems and energy, assistants Ivana Damjanović, Nina Stipetić, and Goran Grdenić participated in the conference.
Among numerous lectures, workshops, and group discussion meetings, Ivana and Nina also participated in the forums of „NGN – Next Generation Network“ and „Women in Energy.“ A technical visit to the 220 kV transformer station with an embedded SVC device was also organized during the conference. Within the NGN technical session, the project DESME – „Development of an expert system for measuring lightning strike parameters and protection of wind turbine blades to reduce failures and downtime“ was presented, currently ongoing with FER and company Porzana d.o.o. cooperation. The paper "Statistical Analysis and Grouping of Measured Power Transformer Overvoltages" (authors: Bruno Jurisic, Tomislav Zupan, Božidar Filipović-Grčić and Goran Levačić) was presented within Study Committee A2 Session– Power Transformers and reactors.
ZVNE members participated in CIGRE Working Group (WG) meetings:
- WG C4.66 - New concept for analysis of multiphase back-flashover phenomena of overhead transmission lines due to lightning (Nina Stipetić, prof. Božidar Filipović-Grčić, prof. Viktor Milardić)
- WG A2.63 - Transformer impulse testing (prof. Božidar Filipović-Grčić)
Conference ENERGY and RES 2022, which was held on Monday, September 5 in Krško (Cultural House), brought together numerous experts from the energy sector, decision makers, investors, utility companies and representatives of the academic community with the aim of discussing the possibilities for cushioning the energy shock and ensuring energy self-sufficiency.
Among keynote speakers was our Professor Zeljko Tomsic, Ph.D. with his presentation: Energy transition and nuclear energy.
The RTL show on August 31, 2022, RTL DIREKT also featured our Prof. Željko Tomšić, Ph.D., who reported on the energy saving measures of the Government of the Republic of Croatia.
The theme of the talk was energy savings in Europe and Croatia. Prof. Tomšić explained why the government's measures come too late.
In the program, the RTL reporter measured the temperatures in hospitals, shopping malls, trains, airports and at FER to see if the government's recommendations are being followed.
Prof. Tomšić emphasized the difference between energy savings and energy efficiency because energy savings lead cost savings, but at an expense of health and user comfort, so the impact of individual saving proposals should be carefully weighed. He emphasized that energy efficiency means achieving the same level of comfort, service, or production at lower energy costs, while conservation, for example, reduces comfort (wearing thicker clothing due to lower temperatures, etc.).

A long-range trip (in Croatian terms, not Siberian, nor Australian) was undertaken with an EV – the Hyundai Ionic5 with a 77 kW battery and a theoretical range of, well, does it even matter? The primary goal was to reach the destination – a wind power plant named VE Voštane in the south of Croatia. Why there? Well, to do a quick installation of a newly developed prototype measuring system named: The expert system for measuring lightning strike parameters on Wind Turbines (FER, patent pending). And of course, to get back with zero CO2 emissions (people breathing was not considered). To kill two flies with a single stone (an old national Croatian saying), an e-mobility test was done on the way. The goal was to test various aspects of e-mobility in Croatia, such as: number of charging stations in rural area, availability, installed power capacity, charging speeds, wait times, travel comfort, travel speed and EV vs fuel car travel times. The V2Load function was used to run the electrical equipment and a laptop.
Celebration of the 166th anniversary of the birth of Nikola Tesla, the Round Table "Hydroelectric power station of Tesla's era today" was held in Gospić. Our professor Viktor Milardic was invited to the #roundtable to held a #lecture "Wind power plants in the Republic of Croatia and lightning strikes in wind turbines".

On the occasion of the UN World Water Day 2022, Professor Davor Škrlec held a lecture at an event organized by the Croatian-Indian Friendship Society on March 18th . The lecture was about the achievements of water management in the EU and the challenges of adaptation to climate change. By adopting the second Circular Economy Action Plan and Water Reuse regulation, which will be put into force in June 2023, the EU will take a step forward in terms of preserving water as a scarce resource and facilitating water reuse as an important part of sustainability. Another two regulations were addressed: the Drinking Water Directive which will improve the quality of tap water and transparency of the water supply business as well as the Urban Waste Water Treatment Directive which will implement new standards regarding microplastics in urban waste waters.
Our professor, Davor Škrlec, PhD, was interviewed on the Croatian Radiotelevision's show Eko zona, in its episode which was broadcasted on March 2, 2022. The topic of the episode was the EU's Regulation on the establishment of a framework to facilitate sustainable investment, otherwise referred to as the Taxonomy Regulation, in which the European Commission has in a delegated act proposed that energy projects involving usage of natural gas and nuclear energy, under certain conditions, become more easily eligible for funding under the European Green Plan. On March 9th, the European Commission adopted this proposed Regulation, which is currently being debated in the European Parliament and it is anticipated that the document will be adopted. You can watch the episode, which was filmed before the war in the Ukraine, here.

Journal Impact Factors are published on an annual basis. Although it should not be considered as the only indicator of the quality of scientific publications, it is definitely the most common one in the research world. Our website automatically generates and presents our publication achievements and there you can see our most recent publications. As can be seen in the figure below, we started publishing heavily in top-class Q1 journals in 2020. So far in 2022, we already have five publications in Q1 journals. The most common Q1 journals in which we are present are IEEE Transactions on Power Systems and Applied Energy. We are proud of our young research assistants and their supervisors for this admirable ongoing achievement.
The situation between Russia and the Ukraine has made people start panicking. They are scared for themselves and their loved ones and are watching the news hoping to find some answers and comfort. More often than not, the media ends up encouraging mass histeria instead of calming things down. Luckily, we have someone who is, dare we say, the biggest expert on nuclear energy and its effects: professor Davor Grgić. Professor Grgić has given a few interviews about these current events and has reiterated that there is no need to panic. One of the interviews can be found here. Dear professor, thank you for giving us a professional perspective and for bringing us comfort through your voice of reason.
To celebrate the International Women’s Day, the women of our Department gathered today to have lunch together. Although we are proud and happy to be working in the atmosphere of respect and equality, we are also aware that there’s a long way to go until our Department gets its first female professor. So we took this opportunity to discuss some necessary improvements to our work environment and diss the patriarchy.
Our professor Davor Škrlec, PhD, participated in a panel discussion on younger generations' misperceptions and lack of knowledge of the EU which was held at the Croatian Journalists' Association. Professor Škrlec stressed that it is essential to educate the youth about European policies well before college. He also highlighted the need to give youth an opportunity to express what problems they are facing and how they plan on dealing with these problems.

Did you know that according to Eurostat data from 2020, 41% of scientists and engineers in the EU were women?
While it can be said that the world of engineering is ruled by men and that technical colleges are mostly “male”, we can definitely say that this is slowly but surely changing.
FER can boast the fact that the number of enrolled female students has grown in recent years, reaching 25% last year which is 3% more than five years ago.
We are glad that all of these young women decided to become part of our world, changing it for the better, just like Hedy Lamarr, Ada Lovelace, Zlata Bartl, Sibila Jelaska...
Because even Beyoncé says: Who run the world?
On February 4, 2022, Mirna Gržanić successfully defended her thesis titled "Innovative models of flexible final customers in operation of smart distributed energy systems".

This year, we can proudly say that the ZVNE has the most beautifully decorated Christmas tree! First, our "big" helpers assembled the tree stand, attached and spread out the branches and then set up the tree in the hallway. Then, on Sunday after enjoying the Saint Nicolas theatrical show at FER, our "little" helpers came to add a bit of their own magic which gave us the final product which you can see in the photos. Thanks kids. You're great! ❤

On the 21st and 22nd of October, fifty of FER's 1st to 5th year students visited the hydro power plant (HPP) Jaruga inside the Krka National Park, HPP Zakučac, HPP Prančevići, the Prančevići dam, HPP Kraljevac and the wind power plant Voštane-Kamensko together with its substation.
This trip was organized through the PowerTrip project which aims to promote Croatia's beautiful nature, low-carbon technology and sustainability and the field of electric power engineering. The PowerTrip project is coorganized by KSET, the Department of energy and power systems and the Croatian chapter of IEEE PES. The 50 students were accompanied by Matej Krpan and Marija Miletić, research & teaching assistants at the Department.
HPP Jaruga is one of the oldest hydroelectric power plants in the world, while HE Zakučac is the largest Croatian power plant and HPP Kraljevac is a living museum where large, old Ganz turbine-generators can still be seen.
We thank our hosts HEP-Proizvodnja and ENCRO for showing us these facilities and for enabling the students to learn more about electric power generation and high-voltage technology.
Take a look below at some of the moments from our awesome trip!
The laboratory is designed as an active household consisting of a series of devices (battery stack, electric vehicle charger and numerous household appliances) whose electricity consumption is managed in order to respond to signals from an aggregator or a power system operator.
Within the DRLab, two projects are being implemented that deal with the demand response from smart households (ANIMATION - HRZZ) and the development of prototypes of connected stationary battery energy storage systems (USBSE - EFRR). Both projects are fully in line with the new power system paradigm according to which current passive electricity customers will become active power system participants.
More information about FER’s new research lab and a few photos can be found below.
Namely, given the increase in the share of renewable energy sources, there are increasingly more non-controllable electricity generators in the system (wind and solar power plants) and the balancing of the system is shifting to the consumption side. It is, therefore, important to act in two directions: to awaken the market for the demand response for households and activate their flexibility and to develop energy storage systems for storing energy from renewable energy sources.
Active consumers who can move their consumption over time, so that it coincides with production from renewable energy sources, are key to a very high share of electricity production from renewable sources and consequently for the sustainable development of modern society. Because of their controllable devices, active consumers can manage their consumption and change their load profiles. Although these devices have relatively small individual powers, their aggregation can achieve great potential in terms of demand response programs.
On Saturday, October 23, 2021, 70 primary-school students accompanied by 12 group leaders visited the Smart Grid Laboratory at FER as part of the RADDAR program. Doctoral students Mateo Beus and Marija Čuljak showed the students a hydroelectric power plant including all subsystems, battery systems, a charging station for electric vehicles and explained the concept of the entire laboratory as well as the power system in general. Following this, the students paid a visit to the Demand Response Lab where prof. Hrvoje Pandzic presented to them what their smart homes will look like in the future. In addition to showing great interest and curiosity for these topics, our future power system engineers gave us some very innovative suggestions on how to improve the lab. Of course, we invited them to help us turn these ideas into reality!
We are proud to announce that and researchers from our department, together with Invento Capital Partners, the North West Croatia Regional Energy Agency (REGEA) and Hrvatski Telekom, have been awarded with the national EIT Urban mobility hub. This way we will be able to support the local innovation ecosystem and start-ups and we will boost innovations in urban mobility.
It's time to make Croatian innovative technologies available to the wider, interntional market.
Our team will be led by professor Tomislav Capuder.
We look forward to new projects and #collaborations and believe that decarbonization of the transportation sector is one of the key aspects of the energy transition. Feel free to contact us if you have questions or collaboration ideas or if you are interested in working with us. You can also find some of our recent published EV research here:
As part of a panel discussion on solar technologies in Croatia held at the Sunny Days conference in Hvar recently, our post-doctoral researcher Ninoslav Holjevac from the Zagreb Faculty of Electrical Engineering and Computing gave a presentation titled ''Solar potential in Croatia in terms of integration into the grid and beyond''.
Holjevac gave an overview of the current situation in Croatia, the development of a system for a better future and solutions for the solar and green transition. "We have reached the point where we must take urgent action. The energy transition is unquestionable. We need it. However, the grid is limited and the one we are currently using was built many years ago; its current capacity is close to being maximized," Holjevac warned. He added that solar energy has not had a dynamic development like wind energy, but this is now certainly changing." All of this together represents a significant increase in demand on the transmission and distribution system. A ‘highway’ must be built which will also enable the integration of large solar panels. We need to take action today in order to overcome problems on time,'' said Holjevac.
He pointed out the significant potential of the Sun in Croatia where there are many locations with 2,500 or more hours of sunshine, noting that we have not yet taken advantage of this: ''There is still a lack of solar panels from Zadar to Dubrovnik; there are too few rooftops solar panels; and there aren't enough solar collectors. There is also a lack of experience needed in order to begin more active project implementation," he said.
Speaking further about problems and opportunities, he noted summer as being a critical period. During peak season, solar panels contribute minimally because the problem with power supply takes place between 9:30 pm and 10:30 pm: “Solar panels are not a solution for grid problems for the period between June to September. Solar energy is great for energy transition as it is inexpensive energy, but we still can’t do without the grid. We need both a grid and solar panels and it is no coincidence that one relies on the other. Batteries and similar technologies help, but to a limited extent. We still can't do without the grid. It will be needed, even with an increase of solar panels on roofs."
He also mentioned the long process of developing the power grid – a 400 kV project lasts 10 years. He stressed that there is an enormous number of requests for connection and the system must keep up with these requests. "The development of the power grid is essential for the continuation of the green transition and the rise of large solar panels. Solar panels will contribute to the problem but will also resolve the problem. I am convinced that from a technical standpoint, things will be solvable. These are all opportunities. They are also in agro solars while the significant pilot project ‘Slavonia’ is unused. Certain surfaces can also benefit from floating solars and, additionally, solar panels are not affected by polluted surfaces. Also, there is opportunity in hydrogen, which is one of the pillars of the energy transition,'' Holjevac listed all the potentials of solar panels.
Finally, he concluded that the development of the system, primarily a 400 kV grid, is needed for further integration of a significant share of solar panels, as well as optimal use of the current capacity and opportunities provided by solutions that are lower in capital and less time intensive. Among other things, changes in the current system, the legislation and the rules are necessary. "We need to develop a dialogue among all stakeholders and move towards a green and sunny future," Holjevac said.
Lucija Matulin, a student of the Department of Energy and Power Systems, won the Rector's Award for her work entitled "Development and implementation of SCADA system simulator for microgrid laboratory" in the category of individual scientific and artistic works. Lucija designed the architecture and implemented a simulation tool to simulate the operation of the SCADA system in the Smart Gird Lab (SGLab) laboratory. This tool has greatly facilitated the work with the laboratory microgrid in Covid conditions and has great potential for upgrading in terms of a more realistic simulation of real network conditions, adding new electrical parameters and use outside the laboratory environment. The research and development was carried out as part of the activities of the project of the Croatian Science Foundation project IMAGINE under the mentorship of associate professor Tomislav Capuder and co-mentorship by Alen Hrga.
Congratulations to Lucija on winning the award! :)
On Thursday, September 2, 2021, Slavica Robic, Assistant Managing Director at North-West Croatia Regional Energy Agency (REGEA), defended her thesis “Method for defining energy poverty threshold based on energy, climate, social and health indicators”, mentored by professor Slavko Krajcar. Her research has contributed to a better understanding of energy poverty as a multidimensional problem which requires a systematic approach. Research has shown that living in energy poverty results in adverse impacts on physical and mental health with decreased ability to take part in activities within the community. The tested method is based on an analytical hierarchy process by which decision-makers can analyse the situation and determine the criteria and measures for mitigating energy poverty. The presented research offers solutions applicable in practice, but also lays a good foundation for further research. Research leading to this thesis has been published in several scientific and expert papers, studies and policy proposals including a chapter in a book.
IMAGINE project manager, professor Tomislav Capuder, along with his team member professor Hrvoje Pandzic, participated in the sixth edition of the SpliTech 2021 international conference. During the conference, members of our team participated as panelists of the PANTERA and SUPERRA projects led by the European Energy Research Alliance. They discussed the presence of Croatian research institutions in projects from the EU program and how this participation should be increased and strengthened by Croatian institutions in order for them to be more present as coordinators and partners in projects under the upcoming Horizon Europe program.
The Department of Energy and Power Systems can proudly say that it has a member who is among the top 1% of the world's best #scientists! Professor Hrvoje Pandzic was included on the list of the most influential scientists for 2019 in a study published by a research group from Stanford University in California. In the study, about 160,000 of the world's most cited scientists in all disciplines were ranked by citations. In addition to this list, a list of the most influential scientists throughout their scientific careers was also published, which includes a total of 47 Croatian scientists.

On Monday, July 26, we connected another set of solar panels to the grid. At this point, FER has 84 kW of installed photovoltaics capacity. Under the assumption that each kW of installed photovoltaic capacity in Zagreb produces around 1100 kWh of electricity, this power plant reduces FER's electricity bill by over 90 thousand HRK per year (1 kWh of electricity in high tariff costs around 1 HRK). Additionally, we are performing peak shaving which reduces our power payments by a couple hundred HRK per month. The photovoltaics installation at FER is an ongoing activity which is led by our research assistant Hrvoje Bašić, with the help of the entire Department of Energy and Power Systems. They were installed with the support of the Croatian Science Foundation, European Social Fund and the Environmental Protection and Energy Efficiency Fund.
With finalizing this installation, we are already starting new projects that will result in new photovltaic capacity on FER's rooftops.
The final week before the vacation season at FER was also a week of great scientific accomplishments as we had two PhD theses defended, both of which resulted in Summa Cum Laude! First, on Monday, July 19, Kristina Pandžić defended her thesis ''Multilevel Optimization Models for Energy Storage Planning and Operation'', while Ivan Pavić on the following day defended his thesis ''Optimal Energy and Reserves Scheduling through Controllable Charging and Discharging of a Fleet of Electric Vehicles''. Both doctorates were defended in the so-called Scandinavian style, as both candidates published a large number of papers in very prestigious scientific journals during their studies. Congratulations, Kristina and Ivan, your work is extraordinary!
The operating cycle at the Nuclear Power Plant (NPP) Krško lasts for 18 months after which an outage takes place. An outage is a planned shutdown of the power plant with the aim of replacing nuclear fuel, performing major maintenance activities, inspections, supervised tests, and technological upgrades called modifications. All of these actions ensure that the power plant can operate smoothly and reliably for another cycle.
The outage 2021 started on April 1 and lasted for 34 days. The main activities included replacement of almost half of the fuel elements in the reactor core and inspection of the reactor vessel, control rod guides, and steam generator pipes. The main modifications from the Safety Upgrade Programme were implementation of an alternative system for Safety Injection (ASI), an alternative system for Auxiliary Feedwater (AAF), an alternative system for Residual Heat Removal (ARHR) and Reactor Coolant Pumps’ (RCP) high temperature seals.
It is important to note that the outage 2021 was carried out in full and successfully despite the coronavirus pandemic. This was the result of protective measures which were undertaken such as wearing FFP-2 face masks, regular disinfection, automatic body temperature measurement at the entrance, testing at the parking lot, and organization of working hours over a 24-hour period to ensure a minimal number of people at the site at the same time.
Around 600 Krško NPP employees and 1900 subcontractors from Croatia, Slovenia and abroad participated in the outage. The University of Zagreb Faculty of Electrical Engineering and Computing (FER) is accredited by the Slovenian Nuclear Safety Administration to supervise safety-related outage activities. Our colleagues Davor Grgić, Siniša Šadek, and Štefica Vlahović from the Department of Energy and Power Systems were involved in the regulatory supervision of Emergency Control Room modification, changes of containment sump level monitoring, installation of a radioactivity monitor on the PCFV exhaust line, testing of fire protections system in the plant’s critical areas and main electrical equipment, testing of containment integrity, performance of Hydrogen passive autocatalytic recombiners (PAR) and performance of Emergency Core Cooling System (ECCS).
Prof. Grgić was interviewed by Nacional to talk about the current state of nuclear energy in Croatia and the world. The full interview can be found here.
We are proud to announce that our PhD student Mirna Gržanić received the best poster award at the 2021 PhD Day. The poster, titled “Innovative models of flexible final customers in operation of smart distributed energy systems”, was recognised by a committee comprised of distinguished professors from FER. Mirna's research interests include active consumers, energy communities, smart distributed energy systems and balance group participation in the electricity markets.
PhD Day was inspired by top universities from around the world, as an open gathering where doctoral students publicly present their research results and everyone interested can get insight into the diversity and quality of scientific work at the faculty. Through this event, we not only wish to increase the visibility of research activities and accomplishments of FER, but also to enrich the existing Research seminar of the doctoral studies at FER, through presentation of results and exchange of personal experiences among the doctoral students. The sixth PhD Day was held on Tuesday, July 6th, 2021.
