Modeling and Power Management of a Remote Stand Alone PV-Wind Hybrid System

The main focus of this study is to design a novel stand alone PV-wind hybrid energy system for remote locations where grid extension is not feasible or is expensive. The hybrid PV-wind stand alone energy system shows higher reliability compared to wind or PV stand alone systems as wind and solar technologies complement each other. A Matlab/Simulink model of an integrated stand alone PV-wind hybrid system using a battery for storage and backup protection is presented. The individual components of the system are discussed and modeled. A novel and unique control strategy is designed and simulated to control the power flow of the system while maintaining the battery charging and discharging limit. In addition, different converter design and maximum power point tracking control are applied to ensure efficient and reliable power supply under various atmospheric and loading conditions.
