This sub-specialization laboratory course is based on the interest of those students would like to get  involved in the topics of operation and planning of intelligent distribution networks, integration of renewable energy sources, principles of energy consumption and storage. The goal of the laboratory measurements and computer assisted tutorials is to promote the application in practice, helping the understanding of the physical background and the comprehension of the different calculation methods.

With passing the related measurements the students will get an insight into the operational methods during normal operation and troubleshooting specialities of the operational systems of the distribution networks. The modern devices of power generation and consumption will be introduced, the effect of electric mobility and energy storage will be analysed while the applied switching devices and its network interaction will be discussed. The students would be familiar with measuring the electrical and mechanical parameters of the static and rotating energy converters and electrical drives are involved in the power generation and consumption.
