Abstract : In recent years, the diminishing availability of fossil fuels has spurred a notable surge in demand for renewable energy. Additionally, the desire for environmentally friendly, pollution-free energy has fueled increased interest in renewable energy sources. Consequently, this shift has led to the decommissioning of coal, oil, and nuclear power plants that rely on large synchronous generators for power generation. These generators are vital for providing system inertia. System inertia plays a crucial role, and any reduction in it heightens the risk of frequency instabilities in the electricity grid. To tackle this challenge, the concept of fast frequency reserve is utilized. A novel strategy for power management in grid-connected mode and during load fluctuations is presented to demonstrate the effectiveness of the battery energy storage system in handling frequency variations and maintaining system inertia. A comprehensive MATLAB/Simulink model of a solar photo- voltaic system with BESS is developed for this purpose. The analysis covers operation in grid-tied mode, investigating power transfer strategies and load variations to demonstrate the effectiveness of the battery energy storage system in changeable frequency variations and maintaining system inertia. The findings reveal no voltage or frequency fluctuations even during load variations, underscoring the superiority of BESS as an option for FFR and in enhancing system inertia.
