Abstract

In a context of rapidly expanding renewable energy resources, the wind power is the most interest. Because of intermittent nature of wind turbines, it is difficult to predict and control the wind power generation. At high penetration level, an extra fast response reserve capacity is needed to compensate the shortage of generation when a sudden variation of wind takes place. In order to manage this uncertainty, to minimize the system losses, and to improve the voltage profiles, the injected power to the grid should be kept at its optimal level throughout the day. This paper presents an approach to keep the injected power at its optimal level by combining the wind power generation system with Plug-in Hybrid Electric Vehicles (PHEVs) and optimal utilizing of vehicle-to-grid (V2G) capacities. Optimal PHEVs charging/discharging can stabilize the injected power of the wind turbines by storing electric energy during high wind speed and deliver it during low wind speed. So, it is important to estimate enough number of participating PHEVs for the desired applications. The proposed approach is tested using a 33-bus distribution system with a variety of case studies and actual wind speed.
