Energy Storage Configuration Considering Battery Characteristics for Photovoltaic Power Station

Abstract

The development of photovoltaic (PV) technology has led to an increasing share of photovoltaic power stations in the grid. But, due to the nature of photovoltaic technology, it is necessary to use energy storage equipment for better function. Thus, an energy storage configuration plan becomes very important. This paper proposes a method of energy storage configuration based on the characteristics of the battery. Firstly, the reliability measurement index of the output power and capacity of the PV plant is developed according to the power output requirements of the grid. Then an immune algorithm is used to find the economically optimal solution for the energy storage configuration based on the advantages of different batteries in terms of power and capacity. Finally, the feasibility of the scheme is verified using data from a PV plant in Qinghai.
