Research on Grid Imbalance Caused by the Penetration of Photovoltaic Power Generation in Distribution Systems
This article analyzes the impact of photovoltaic penetration rate on the power grid and simulates the most obvious factors affecting voltage fluctuations in the distribution system to analyze the severity of the problem under different levels of photovoltaic penetration.Through simulation analysis,it can be concluded that as the photovoltaic penetration rate increases,the required number of transformer tap conversions increases,leading to a shortened serv-ice life of transformers.Therefore,by adjusting measures,the voltage is adjusted within the allowable range of the standard.
