摘要
为促进储能的推广应用,充分挖掘其在电网中的潜在应用场景,对基于电网应用的储能降网损方法展开研究。基于电网网损的产生机理,结合储能系统的有功、无功四象限运行特性,提出利用储能降低电网网损的方法,提炼效果评价指标,并基于此,利用灵敏度分析方法,就储能充放有功和无功功率对电网的影响进行仿真分析,分析并探讨储能的作用布点原则;最后,以某IEEE 9节点电网为例,通过仿真分析验证该方法的有效性和可行性。
In order to promote the popularization and application of energy storage and fully explore its potential application scenarios in the power grid,this paper presents a study on the method of energy storage and grid loss reduction based on grid application.Based on the generation mechanism of power grid loss,combined with the active and reactive four-quadrant operating characteristics of the energy storage system,a method of using energy storage to reduce the grid loss of the power grid is proposed,and the effect evaluation index is refined accordingly.Based on this,the sensitivity analysis method is used to simulate and analyze the impact of charge and discharge active and reactive power on the power grid,and analyze and discuss the distribution principle of energy storage.Finally,an IEEE 9-node power grid in Northwest is taken as an example to verify the effectiveness and feasibility of the proposed method through simulation analysis.
