A New Stand-Alone Hybrid Power System with Wind Turbine Generator and Photovoltaic Modules for a Small-Scale Radio Base Station

This paper proposes a new stand-alone hybrid power system with a wind turbine generator and photovoltaic modules for a small-scale radio base station. We studied the system characteristics by simulation of operation on Yonaguni Island, where wind speed exceeds 4.0m/s throughout the year, and average annual wind speed is about 7.0m/s. The results of simulation show that, to attain a system operation rate of 100%, the base station equipment requires a wind turbine generator output power of 8kW, a photovoltaic output power of 7.6kW, and 3-day backup storage batteries.
