Photovoltaic (PV) Contribution to the Primary Frequency Control

Abstract

Photovoltaic (PV) technology is among the most efficient and cost effective renewable energy kinds currently available on the market. The connection of a large number of PVs to the grid may infuence the frequency and voltage stability of the power system. This paper proposes load-frequency control technique for a system with high penetration of Photovoltaic (PV). The proposed controller has been successfully implemented and tested using PSCAD/EMTDC. In this study. The impact of Photovoltaic (PV) on the frequency stability of the system is studied in detail. This study shows that large penetration of Photovoltaic (PV) with load and frequency control has a significant impact on the stability and security level of the electrical network
