Research on grid-connected control technology of PV based on virtual synchronous generator
The output power of photovoltaic power stations is affected by environmental factors such as light intensity and temperature,and has a strong fluctuation.Therefore,in order to improve the efficiency of photovoltaic grid-connection and protect the quality of power grid,virtual synchronous generator is a more common technology and means.Based on this,on the basis of analyzing the grid-connected characteristics of photovoltaic power generation,this paper focuses on the specific implementation and application of virtual machine technology from three aspects,such as power tracking control power electronic transformation control and photovoltaic grid-connected protection,and carries out simulation evaluation of its control effect,in order to achieve grid-connected control of photovoltaic power plants.
