摘要

针对光伏发电系统中蓄电池的放电深度提出了一种估算方法

该方法根据当地的日均光照辐射量

利用正态分布建模计算出时均光照辐射量

结合当地负载不同时间段的耗电情况

估算出蓄电池工作一天的放电深度。该方法解决了许多地区缺乏时均光照辐射量相关数据的缺陷

为估算蓄电池放电深度提供了实用便捷的计算手段。以新疆某地光伏发电系统为例

分步介绍了估算蓄电池放电深度的方法。并用PV&SOL进行了模拟仿真

验证了文中所提出方法的可行性。

Abstract

An estimation method of depth of discharge（DOD） of lead-acid battery in photovoltaic power generation system is proposed. This method calculates irradiation per hour by developing normal distribution model of irradiation per day. Then DOD of battery can be calculated by analyzing both the hourly irradiation and load requirement. This method solves the problem of shortage of hourly climate data in many regions. What is more

this method is introduced in detail by taking the photovoltaic power generation system in Xinjiang as an example. At last

simulation of the same generation system is executed by PV & SOL which verifies the proposed method.
