Analiza uticaja ispada proizvodnih jedinica u TENT A i B na gubitke u prenosnom sistemu Srbije

This paper analyses the impact of outages of large generating units in the electric power system of Serbia. In December 2021, there was an outage of the largest thermal capacities - thermal power plants Nikola Tesla A and B. At the same time, the wind generators did not produce much power, due to unfavourable weather conditions, i.e. low wind speed. At the same time, the total installed capacity of wind power plants in Serbia is not large. In order to compensate for the deficiencies, it was necessary to import electricity. All of the above had the effect of changing the power flows in the branches of the electric power network. Importing electricity significantly increases the distance between the source of electricity and the consumption. This leads to the conclusion that there will be a change in the total losses of electrical energy in the system. The paper analyses how much the losses would be in the power system if the Nikola Tesla thermal power plants A and B were in operation and what the losses would be if the wind farms were working at full capacity.
