光伏发电项目储能容量的计算分析

Calculation and Analysis of Energy Storage Capacity for Photovoltaic Power Generation Projects

文章论述了储能系统在新能源发展中的重要作用和当前主要的储能型式。提出了“最大储能容量”、“储能平衡容量”等新概念及其计算方法。其中“储能平衡容量”是在电价、储能造价、系统运行方式等外部条件确定的前提下,通过分析计算确定的储能容量。以某大型光伏配套储能项目为例,利用“储能平衡容量”的概念和理论方法对电源侧或用户侧储能系统的容量配置进行计算分析,并对影响储能容量的几个敏感因素进行了敏感性分析。

This paper discusses the important role of energy storage systems in the development of renewable energy and the current primaryforms of energy storage.It introduces new concepts like"maximum energy storage capacity"and"energy storage balance capacity"along with their calculation methods.The"energy storage balance capacity"is calculated through analysis under external conditionssuch as electricity prices,energy storage costs,and system operation methods.Taking a large-scale photovoltaic and energy storageproject as an example,this study utilizes the concept and theoretical methods of"energy storage balance capacity"to analyze andcalculate the capacity configuration of energy storage systems on the power supply side or user side.It also conducts a sensitivityanalysis on several factors affecting energy storage capacity.
