Abstract

The increasing number of renewable energy sources connected to the low voltage network (LV) causes that the quality of electricity in the network deteriorates. One of the methods of improving the quality is the installation of energy storages, ie. batteries, supercapacitors or flywheels. Energy storages can effect the load levelling, compensate reactive power and harmonics or reduce the load asymmetry [1]. The cost of purchase and operation of energy storages is unfortunately high. Therefore, we should focus on the adequate placement of the energy sources in the network. The article presents, on the basis of literature studies, a review of methods of the electrical energy storages placement in the LV network.

Streszczenie

W związku z rosnącą liczbą źródeł odnawialnych przyłączanych do sieci niskiego napięcia (nn) jakość energii elektrycznej w tej sieci ulega pogorszeniu. Jedną z metod jej poprawiania jest instalowanie zasobników energii, tj. baterii akumulatorów, superkondensatorów czy kół zamachowych. Zasobniki energii są w stanie złagodzić dobową zmienność obciążenia, skompensować moc bierną i wyższe harmoniczne oraz zmniejszyć asymetrię obciążenia [1]. Koszt zakupu i eksploatacji zasobników jest niestety wysoki. Dlatego też istotnym elementem jest ich odpowiednie rozlokowanie w sieci. W artykule przedstawiono, na podstawie studiów literatury przedmiotu, przegląd metod wyboru lokalizacji zasobników energii elektrycznej w sieci nn.
