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

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.
