Abstract:

With the increase in photovoltaic installations,its requirements for energy storage systems are also increasing.There is an urgent need for the research on the demand for energy storage systems in actual operation of photovoltaic power generation.The purpose of this paper is to reduce the waste light rate.First,the paper carries out the analysis of the output characteristics of the light storage and the extraction of the characteristics of the energy storage system,puts forward the expected value of the demand for the energy storage equipment under the operating conditions,and then establishes the mathematical model of the energy storage system output,and taking the light rate working condition as an example,verifies the charging and discharging state of the energy storage under the selected working condition,and finally obtains the demand of the energy storage system under the working condition.

Key words: photovoltaic energy storage system, working conditions, light storage output, reduction of light abandonment rate
