Poboljšanje rada distributivne mreže u uslovima velikih opterećenja korišćenjem fotonaponskih i sistema za skladištenje energije

Abstract

This paper considers the improvement of distribution network operation in high load conditions using photovoltaic (PV) and energy storage systems (ESS). Optimal locations and powers of PV systems and ESS, considering the improvement of distribution network operation, are determined by metaheuristic optimization method of genetic algorithm (GA), where losses in distribution network and its voltage profile are used as quality indicators for distribution network operation. Two approaches are used to determine the optimal power of PV system during the day, depending on the ratio of injected power into the network by the PV system and its maximum available power at a given time. Cases with different load distributions in the distribution network are analyzed, as well as the cases with different number of connected PV systems and ESS. Based on the obtained results, in addition to determining the level of distribution network operation improvement, conclusions are given regarding the impact of load diagram on the number, location and size of PV systems and ESS.
