Integration of distributed generations (DGs) to distribution systems has posed several technical challenges for network operators. One of the main problems that has received widespread attention is the voltage rise issue. This issue has led researchers worldwide to find ways to control voltage so that an acceptable limit is maintained and delivered to consumers. In networks with DGs, the methods of voltage control have been identified as coordinated or centralized control and decentralized control. This paper presents the results and comparisons of a simulation that used these decentralized voltage control methods in managing voltage rise issues in distribution systems with DGs. Streszczenie. W artykule przedstawiono porównanie metod sterowania zdecentralizowanego, wykorzystywanego do kontroli dopuszczalnej amplitudy napięcia w sieci, zawierającej rozproszone generatory energii elektrycznej. W tego rodzaju sieci możliwe są nieoczekiwane, skoki napięcia, co przekłada się na jakość energii, dostarczanej do użytkowników i działanie odbiorników. (Porównanie zdecentralizowanych metod kontroli napięcia w kontroli skoków napięcia w aktywnych sieciach elektroenergetycznych). Keywords: Distributed generations (DGs), voltage rise, centralized and decentralized methods, voltage control. Słowakluczowe: Generacja rozproszona (DGs), skok napięcia, metody zcentralizowane i zdecentralizowane, kontrola napięcia. 1. Introduction The presence of distributed generations (DGs) in distribution systems has created several challenges and disadvantages in terms of delivery of power quality, protection issues, and voltage support. The need for distribution network operators (DNOs) to control voltage at its acceptable limits is required to maintain the delivery of power to the customers. Effective delivery of power consequently reduces the issues of power quality and losses. According to [1], an active distribution network (ADN) is defined as a distribution net[...]
