Wind and PV hybrid renewable system dispatch using battery energy storage

Increasing electricity demand reveals the challenges presented by limited resources and environment impacts. As an alternative to conventional plants, renewable resources such as wind power and PVs account for an increasing percentage of electricity generation in recent years. Although renewable resources have many advantages, their intermittent nature must addressed before large scale application. Unlike wind power, which usually has higher power output at night and in the early morning, solar power only exists during daytime. This paper proposes the idea of combining wind turbines and PVs at different capacity ratios to match the hybrid system output to the system load profile. With an optimal capacity ratio, feasibility studies are also made by adding battery storage to the hybrid system to dispatch total hybrid output.
