In MATLAB, creating a model for a grid-connected solar PV battery system involves developing a simulation environment that integrates photovoltaic (PV) panels, batteries, and grid connections. The model considers factors such as solar irradiance, battery state-of-charge, grid voltage, and power demand. MATLAB provides tools for designing the PV array, simulating solar energy generation, modeling battery behavior, and implementing control strategies for grid interaction. Engineers can analyze system performance, optimize energy management algorithms, and assess the impact of different configurations on grid stability and energy efficiency. By simulating various scenarios and optimizing system parameters, MATLAB enables the development of grid-connected solar PV battery systems that enhance renewable energy utilization, support grid integration, and contribute to sustainable energy practices.
