Modelling and Control of BESS for Solar Integration for PV Ramp Rate Control

PV power varies with the passing of clouds; these variations can affect power quality and system uniformity. PV system is combining with a storage device to mitigate the variations in power. During the fast movement of clouds causes sudden changes in power. Sudden changes can limit through ramp rate control. In this work employing a ramp rate control with energy storage system is capable of maintaining the system stability. This work is aimed to design a battery-based storage system for integration with considered 500 kW solar photovoltaic power plant using ramp rate control method. The control scheme is tested and validated using MATLAB/Simulink environment.
