摘要:

针对集群储能电站在风电并网电力系统中容量和选址规划问题,提出集群储能电站节点选址、容量配置方法。首先,针对功率传输分布系数,分析论证储能电站分区配容和有功调频能力的影响机理,提出储能电站定容和选址思路;其次,综合考虑系统功率敏感度相似度、有功调频及储能投资3个方面,以系统功率扰动敏感度对系统进行分区,以有功占比最小、发电站与储能电站等年值投资成本最小为目标构建集群储能电站定容-选址的一体化规划模型。最终,以Matpower工具中30节点电力系统网络为例,验证了所提方法的有效性和可行性。

Abstract:

In order to solve the problem of capacity and location planning of cluster energy storage power stations in wind power grid connected power system,this paper proposes a method of node location and capacity allocation of cluster energy storage power stations.Firstly,according to the distribution coefficient of power transmission,the influence mechanism of zoning capacity distribution and active frequency regulation capacity of energy storage power station is analyzed and demonstrated,and the ideas of constant capacity and location of energy storage power station are proposed.Secondly,considering the similarity of system power sensitivity,active power frequency modulation and energy storage investment comprehensively,the system is divided by the sensitivity of system power disturbance,and the integrated planning model of constant capacity-site selection of cluster energy storage power stations is built with the objective of minimizing the active power proportion and the annual investment cost of power station and energy storage power station.Finally,a 30-node network in Matpower tool is taken as an example to verify the effectiveness and feasibility of the proposed method.

Key words: cluster energy storage power station, fixed capacity site selection, PTDF, zoning capacity distribution, active frequency regulation capacity
