New project!

We are deligthed to announce that FER, lead by the team from our department, is starting a new project! 💡📃

This time, it is not the typical one, but infrastrucured – we are starting a construction of a new 600 kW solar power plant 🌞 and a battery storage 🔋 unit to support it. With this new system our total capacities will be increased up to 700 kW of PV on the AC side and over 300 kWh of storage in batteries, covering a bit over 50% of total faculties electricity needs and reducing our carbon footprint by 109 tons annually. It also opens up other possibilities and brings additional benefits: not only will we be promoting large integration of renewables, but our students will have the opportunity to be part of FER's living lab, learn, research and develop new ideas based on data collected from the system. 🔍

We believe this is the first of many good news and projects to come in fulfilling our long term goal of carbon neutrality and energy efficiency. ⚡ ☘

Project is financed by Island, Lichestein and Norway through European economy space 2014. – 2021. with national cofunding of Republic of Croatia in the amount of 690.000 € from the program Energy and Climate Change.

FER is the sole partner in the project and the total value of the project is 815.000€.

DINGO does not only exist in Australia 😆

We love a good challenge and when our colleagues from HELB and Sedam IT asked us to join them in the #DINGO project we did not hesitate for a second. Over the last two years we have been developing a set of solutions with the goal to empower our distribution system operator (HEP ODS) to become an enabler of the energy transition. The black box of the low voltage grid will soon, hopefully with the help of our solution, become more efficient and in turn able to integrate higher shares of low carbon technologies such as PVs or electric vehicles. The algorithmic part of the solution is developed by FER (FER - Department of Energy and Power Systems) but our colleagues from HELB and Sedam IT are to be credited for turning it into a market ready product. We would not be able to do any of this if our colleagues from HEP ODS were not there to provide us inputs, data sets and pilot sites where our solution is currently being tested and verified.
 
Last week, our friends and colleagues from Faculty of Electrical Engineering, Computer Science and Information Technology Osijek (Danijel Topić, Goran Knežević, Šljivac Damir, Kresimir Fekete, Srete Nikolovski, PhD. MSc. Dipl.ing. SMIEEE, zvonimir klaic, Tomislav Matic, Emmanuel Karlo Nyarko, Marinko Barukčić, Mario Vranješ, Josip Balen) have invited us to present above mentioned results in a Special Session at the SST 2022 conference in Osijek. Our team, which presented these results, was: Terezija Matijašević, Tomislav Antić and Tomislav Capuder. Thanks again for hosting us at one of the most enjoyable conferences there is! We are already looking forward to the next SST 2024 event. 🎉
 
We would also like to thank HAMAG-BICRO - Croatian agency for SMEs, Innovations and Investments for funding us and assisting us with so many things through this entire process.

We do more than "just...

Around two years ago, with our colleagues from Intis engineering, we embarked one of the most challenging journeys one can take in Croatia – developing of hardware and software product from scratch. The design, dimensioning, optimization, control, hardware, assembly, testing etc. – all this was done in Croatia by our friends from Intis and engineering and us. This week we were finally able to live test what we have been developing. Its always stressful when you “play” with high voltage/currents, but as you can see from the photos the tests were a huge success! And we won’t stop here, so stay tuned from more great news like this. 😄

We thank Hamag Bicro for funding us and assisting us with so many things through this entire process.

Also, big thanks to people who were working on this project: Frane Zdunić, Drago Romić, Tomislav Capuder, Hrvoje Pandžić, Mateo Beus, Mirna Gržanić, Alen Hrga, Bojan Franc

Professional development - Vis

Last weekend of September was quite exciting for our Department. We first visited hydropower plants Gojak and Lešće, where the local experts welcomed us and gave us a tour of both power plants. While hydro power plant Gojak has been in operation since 1959, hydro power plant Lešće is the only medium-scale power plant (installed capacity 41,2 MW) constructed in Croatia in the last 30 years. Then we traveled to the island of Vis to take a tour of the first large-scale battery facility (1,45 MWh) coupled with a 3,5 MW solar power plant. This hybrid facility will provide security of supply to this remote Croatian island, especially important during the tourist season. In the rest of the year the battery storage will be used for arbitrage and provision of frequency ancillary services. All the visited facilities are owned and operated by HEP, while the battery storage is currently being commissioned by Končar INEM. We would like to thank to all our hosts for this insightful and highly informative technical visit.

Energy savings in Europe and Croatia

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.).

Croatia E-mobility Long-range test...

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.

A new research laboratory was...

In September 2021, a new research laboratory, the Demand Response Lab (DRLab), was established at FER, headed by professor Hrvoje Pandzic.

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!

The development of the power grid is...

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.

Additional photovoltaic capacity...

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.

Outage in the Nuclear Power Plant Krško

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).
