With the increasing scale of photovoltaic (PV) power generation on distribution network side, the dynamic behavior of PV generation system has significant impact on the comprehensive load characteristics on distribution network side, and it is very important to establish a load-oriented equivalent model of PV generation system. A grid connection simulation platform of PV generation system is built based on MATLAB/Simulink. Considering PV generation system as a generalized load and analyzing its dynamic operation characteristics in transient pro...
