3. apply proper design of electricity distribution network regarding their function
4. assemble electricity distribution network
5. analyze and forecast load demand in distribution networks
6. analyze and planinng of electricity distribution networks
7. design of electricity distribution networks with integrated distributed generation
8. evaluate impactof distributed generation on operation of electricity distribution networks

Lectures

Lectures have blendid or mixed learning approach. Part of lectures are in live in the classroom, using old and modern presentation techniques, short movies and simulations in software. Additional literature, numerical example, simulations and internet links are available for the students in Moodle.

Exams

Writen examination consist of solving numerical examples that represent simplification of real engineering problems from the domain of distribution networks and distributed generation. Oral examination is focused on the assesment of creativity in solving real engineering problems from the domain of distribution networks and distributed generation using.

Exercises

Solving numerical examples and simulations.

Structural Exercises

Students have unique project with distribution network calculations before and after connection of distributed generation in the part of real distribution network.

E-learning

Moodle is used for distribution of educational material and assesment.
