提升配电网新能源消纳能力的分布式储能集群优化控制策略

Optimal Control Strategy of Distributed Energy Storage Cluster to Improve the New Energy Consumption Capacity of Distribution Network

从实际情况来看,当前配电网与分布式电源构建连接后,经常会出现各种故障问题,尤其是能源消耗及集群储能成本过高极为显著。针对这类问题,我国积极开展电力能源相关研究,并对分布式电源消纳和储能系统进行优化,促使集群储能功能更加完善。首先构建分布式储能集群系统各项指标,基于基础指标体系优化集群策略。其次逐层对配电网进行削峰填谷,对集群层面采取同样方式进行干预,从而保证储能效率。在综合考虑情况下,构建安全、稳定运行的集群储能经济模型。最后基于构建的模型和指标体系,综合了解储能系统的运行收益及能源消纳比例。经过验证所提控制策略可以有效提升储能系统的经济效益。

From the actual situation,after the current distribution network is connected with distributed power sources,various failure problems often occur,especially the high cost of energy consumption and cluster energy storage is extremely significant.In response to such problems,my country has actively carried out researches related to electric power and energy,and optimized distributed power consumption and energy storage systems to make the cluster energy storage function more complete.Firstly,various indicators of the distributed energy storage cluster system are constructed,and the cluster strategy is optimized based on the basic indicator system.Secondly,the distribution network is shaving peaks and valleys layer by layer,and the cluster layer is intervened in the same way to ensure the energy storage efficiency.Under the comprehensive consideration,build a safe and stable economic model of cluster energy storage.Finally,based on the constructed model and index system,comprehensively understand the operating income and energy consumption ratio of the energy storage system.After verification,the proposed control strategy can effectively improve the economic benefits of the energy storage system.
