Abstract

Small-hydro power station is often used in remote area beside a river, but it doesn´t match electricity demand so well, especially in dry season. A photovoltaic (PV) system with battery is a suitable option to complement the electricity gap. In this paper, a new structure of MW-class PV system integrating battery at DC-bus is proposed to be used in hydro/PV hybrid power system, and 4 main designing considerations and several key equipments are discussed. In 2011, a 2MWp PV station with the proposed structure was built up in Yushu, China. From stability analysis, the station shows a strong stability under load cut-in/off and solar irradiance´s fluctuation.
