摘要 

根据主动配电网中储能系统作用不同,提出了一种基于复合储能的主动配电网容量配置方法。以兼顾复合储能系统加入后分布式能源的波动率最小及整个主动配电系统负荷缺电率最小为目标函数,实现主动配电网系统的供电可靠性和经济性。首先,对比分析复合储能和单一储能对平抑新能源波动的效果;其次,选取不同滤波时间常数在满足优化目标的前提下配置系统容量,对比两种储能形式容量需求;最后,采用自适应遗传算法进行多目标优化,设置不同的权重系数,在抑制分布式能源波动的情况下合理地减小负荷的缺电率。

Abstract

According to the active distribution network storage system,this paper presents an active distribution network capacity allocation method based on composite energy storage.To balance the composite energy storage system after adding the distributed energy fluctuation rate and the minimum active power distribution system load outage rate minimum as the objective function,realize the power supply reliability and economy of active distribution network system.First,comparative analysis of composite energy storage and single storage effect on new energy to stabilize the fluctuation effect;secondly,select a different filter time constant in meet the optimization objectives under the premise of allocation of system capacity,comparison of the two forms of energy storage capacity requirements;finally,an adaptive genetic algorithm for multi-objective optimization,set different weights,in to reasonably reduce the load power of inhibition rate distributed energy fluctuations.

Key wordsActive distribution network    hybrid energy storage    capacity configuration    multi-objective optimization    improved genetic algorithm
