Abstract

A 5 MWp PV solar power station will be installed in a remote area of China. This new system may contribute to addressing the area´s serious electricity shortage, while also minimizing damage to the environment. The PV station consists of photovoltaic generation system and battery energy storage system, which combine with the existing small-hydro facility to form an autonomous hybrid generation system. In this system, the small-hydro works in V/f control mode, the PV and battery storage systems work in P/Q control mode to make full use of solar energy and reduce the amount of water and diesel used. In this paper we analyze and evaluate the stability of the hybrid system using a PSCAD simulation. Reasonable measures and recommendations are proposed based on these results.
