Learning Outcomes

  1. Calculate currents and voltages in distribution networks
  2. Explain the process of connecting a new user to the distribution network
  3. Explain the different structures of distribution grids
  4. Analyze and calculate the future consumption in distribution gnetworks
  5. Arrange the elements of distribution networks in a functional unit

Forms of Teaching


The students will be given a theoretical background of multiple aspects of distribution networks, including latest trends, innovations and concepts in operation and planning of distribution networks. The lectures will be supported by power point slides, written notes and examples from rea-world provided by teachers in the classroom


The exercises are following the lectures and are composed of numerical examples strengthening the theory from the lectures.


The laboratory exercises are conducted in specialized tools used by the distribution system operators as well as in programming language Phyton (basics), the support the numerical examples from the exercises
