This article focuses on the simulation analysis of the stability of an off-grid photovoltaic power generation system in a building using ETAP power system simulation software.Establish a single-line diagram model of the system to study the impact of changes in photovoltaic power capacity on the steady-state performance of the power system.Through the power flow analysis of the system under different photovoltaic penetration rates,obtain the voltage and current distribution of the system during steady-state operation and the transient current during short-circuit conditions,thereby achieving stability analysis of the off-grid photovoltaic power generation system.Compared to traditional Matlab simulations,this method is more concise and more realistic for numerical simulation at the system level.The simulation results verify the correctness and effectiveness of the proposed method in this paper.
