计及新能源功率概率分布特征的储能配置优化方法
An energy storage configuration optimization method considering power probability distribution characteristics of renewable energy
摘要
Abstract
In order to reduce the influences of renewable energy power fluctuations on power systems,an energy storage configuration optimization method considering renewable energy power probability distribution is proposed in this paper.Firstly,calculate and count the renewable energy power fluctuations at different time scales,and determine the probability distribution characteristics of renewable energy power.Secondly,according to the probability distribution characteristics and the grid-connected index of renewable energy,the configuration optimization model of energy storage considering the renewable energy time-scale and power fluctuation is set up.Thirdly,based on the given constraints and time scale,calculate the minimum energy storage charging and discharging power where the fluctuations meet any set probability levels,thereby determining the rated power,capacity and initial state of the energy storage.At last,through calculation and analysis using the data measured from a 50 MW photovoltaic power station,the method is proved to be correct and effective.This method only compensates the fluctuated power that does not meet the fluctuation index,and has no impact on the power that has already satisfied.关键词
