Abstract

In this work, we address the load-frequency control issue caused by a varying load demand in an interconnected power system. A frequency control method is proposed by integrating photovoltaic (PV) system and a battery energy storage system (BESS) in a sample two-area thermal power system. A linear incremental model for PV is developed and used for simulation studies. A MATLAB simulation of the system has been carried out, and the simulation results show that the frequency fluctuations following a step load perturbation can be effectively contained with PV–BESS combination.
