Challenges of the Transmission System Operator to Managing Distributed Generation and Consumption

Meeting the target objectives of the European Union by 2030 is to reduce greenhouse gas emissions by 40% (compared to the reference 1990) and the share of renewable energy by at least 27% of the total energy consumption, has led to an ever-increasing integration intermittent renewable energy sources (RES). The largest share of intermittent renewable sources of electricity is occupied by wind power plants and solar power plants. In the beginning of the integration of intermittent renewable sources on the transmission network, the problem of balancing the electric power system (EPS) caused the impossibility of managing the production of the mentioned power plants due to their dependence on weather conditions (sun and wind). To solve this problem, technical measures for balancing the EPS system have been analyzed and defined using conventional production facilities such as gas thermal power plants and accumulation hydroelectric power plants. However, as the installed capacity of RES increases over time, so it is the bigger need for balancing energy in the power system both on the transmission and on the distribution grid. In the paper is presented challenges of the transmission system operator to solve the problem of balancing power system when increasing the installed capacity from the RES by, among other things, managing distributed generation and consumption in the distribution network.
