چکیده

This paper presents power management and dynamic assessment of a small hybrid wind and photovoltaic (PV) energy system integrated with battery storage as the auxiliary power source. The system consists of a small wind turbine, photovoltaic cells, a battery, and an electric power converter. The load is supplied with the contribution of all renewable energy sources through an energy management system. Excess wind and photovoltaic energy is redirected to charge the battery. This hybrid energy system is stand-alone, reliable, and ultra-high efficient. A boost converter and a DC/AC inverter are utilized to produce a constant and reliable AC output voltage. The control strategy of voltage regulators is based on PI controllers that are tuned using the particle swarm optimization (PSO) algorithm. The dynamic response of the system to variations in the power source and the load is investigated. Simulation results show the strong self-adaption of the system to sudden operational variations. The combination of wind and PV sources is well-suited for the geographical regions with both windy and sunny days. This standalone system is ideal for suburban and rural areas remote from the electrical grids.
