Operation and Control of a Stand-alone Hybrid Renewable Energy System

The increasing global interest in renewable energy-based power systems is fuelled by their abundance and environmentally friendly characteristics. Hybrid Renewable Energy Systems (HRES) represent a novel development, integrating multiple sustainable sources like wind turbines, solar photovoltaic (PV) systems, and other renewables like ocean, wave, and geothermal energy. Integrating multiple renewable energy sources such as solar, wind, hydro, and biomass and energy storage systems as a backup for the reliable power supply has been considered. To ensure uninterrupted power supply to the growing community and industrial sector, proper synchronization and management of alternative power sources are imperative through an energy management system. The hybrid energy system optimizes power-generating module quantities and sizes, including PV systems, wind turbines, batteries, and diesel generators, while meeting load requirements. Implemented in MATLAB Simulink, alongside a full model of the hybrid renewable energy systems, simulation results illustrate the effectiveness in maintaining voltage and frequency within acceptable ranges during diverse operating conditions. In conclusion, this manuscript offers a comprehensive study on the optimization and control of a solar-wind hybrid renewable energy system, serving as a valuable tool for designing and operating such systems in remote and islanded communities.
