摘要:

基于光伏发电装机的增加,其对储能系统的要求也日益增加。以减小弃光率为目的,首先开展光储出力特性分析及储能系统工况特征提取,提出工况对储能设备的需求期望值;其次建立储能系统出力数学模型,并以弃光率工况为例,验证所选取工况下储能充放电状态;最终得出在该工况下储能系统的需求。

关键词: 光伏储能系统, 工况, 光储出力, 减小弃光率

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
