9.1 INTRODUCTION
Separate photovoltaic or wind power generation can achieve a major output fluctuation due to random and intermittent wind/solar resources and needs prodigious battery volume to satisfy load. Actually, the photovoltaic and wind power generation have commendable complementary characteristics in time distribution. The solar energy is adequate and the wind is weak in daytime, while the solar is weak and the wind is strengthened due to the earth’s surface difference in temperature at night. In summer, the solar is strong but wind is weak, while the wind is strong but the solar is weak in winter. Taking full advantage of the complementary characteristics of wind and solar can achieve a high power supply reliably, while it can reduce the total cost of the system in the meantime [1].
