“…In recent years, in order to alleviate the energy crisis, with the strong support of the government, a large number of distributed renewable energy sources such as photovoltaic and wind power have been connected to the distribution network. Photovoltaic power output is closely related to meteorological conditions such as temperature and light intensity, and presents a strong uncertainty with the change of meteorological conditions, which makes the power flow of the distribution network change frequently, causing voltage fluctuations and flickers, seriously affecting the local production and life [4][5][6].…”
