Research on The Influence of Photovoltaic Low Voltage Ride Through Characteristics on The Operation Characteristics of Receiving-end Grid

This paper first establishes a photovoltaic generator electromechanical transient simulation model considering low voltage ride through (LVRT) and its recovery process dynamic simulation, and then studies the impact of photovoltaic low voltage ride through characteristics on the transient voltage rise of new energy generator under large disturbance impact. Based on the analysis and summary of the model structure and corresponding mechanism of distributed new energy in China, the influence of photovoltaic low voltage ride through characteristics on the operation characteristics of receiving end power grid is studied.
