Research

Operation, planning and maintenance of electrical power system

The goal of the research is to elaborate and propose new methods for assessing voltage conditions in the network, tracking power flows, voltage stability, planning the generation and network expansion.

Electric drive vehicles

The research is to oversee the impact of electric-drive vehilces impact on the electricity network, the additional load on the network, the additional costs of losses, installation, operation and maintenance of charging stations with regard to the type of charging technology technology. Additionaly, the goal is to optimally distribute chargers in the road network, with regard to the chargingreliability, the quality of the charging service and the impact on the network.

Investments efficiency in electrical power system

The main objective of the research area is to assess the efficiency of investments in the EPS based on the newly introduced indicators considering the technical impact and the costs of the new investments.

Impact of electric-drive vehicles on power system reliability

The field of research relates exclusively to the power network part, which means that we are interested in the issue of ensuring a reliable power supply. We do not deal with trading and market activity issues. The question that opens at this point is how the system operators provide reliable power supplies. In the first place, the answer requires the definition of the reliability of the EES. The reliability of the EES therefore represents the ability of the system to carry out its task, i.e. supply of electricity to customers. In order to ensure reliable operation of the EES, it is primarily its safety, taking into account, in particular, the reliability criterion N-1 and the adequacy of production and transfer capacities. In this research, we intend to measure the reliability of the EES with the LOLE (Loss of Load Expectation) and EENS (Electrical Energy not Supplied) indicators, because they are often used in practice and in research, and in any case, these indicators can be replaced by others.
