Interconnection Study and Optimization of Grid Connected Photovoltaic System Using Electromagnetic Transient Program

Abstract

This paper presents the interconnection study of a photovoltaic (PV) plant model with a transmission test system using an electromagnetic transient program (EMTP). The effects of PV controller gain parameters on the system s response are investigated. Then, the PV system control parameters are optimized using Particle Swarm Optimization (PSO). It is observed that the controller gain parameters of the PV model have a significant impact on the PV plant s response and its interaction with the system, which can be tuned to reduce the negative effects by implementing optimization techniques.
