摘要

对储能系统提高系统低频振荡稳定的机理进行研究。将阻尼转矩分析（DTA）方法扩展至包含储能元件的复杂多机系统，研究了储能元件阻尼转矩的产生、传递、分配及影响模态阻尼的机理，在此基础上提出了基于DTA的储能系统安装定位、附加稳定控制通道选择及稳定器参数配置的整定方法。计算结果和仿真表明，通过DTA方法能正确揭示储能系统抑制低频振荡的机理，同时也验证了储能系统整定方法的可行性。最后给出了该方法在实际大规模电网中应用的实例。

Abstract

Energy storage system（ESS） is of great potential to be applied to suppress power system low-frequency oscillation（PSLFO）. This paper presents an in-depth investigation on the mechanism about how and why ESS can effectively provide damping to PSLFO. The conventional method of damping torque analysis（DTA） is used to reveal how the damping contribution from ESS is distributed in a multi-machine power system， and affected the damping of power system oscillation modes. Based on the revealed damping distribution of ESS， a new method is proposed to design ESS stabilizer. Analysis and simulation results show PSLFO suppression mechanism by ESS with DTA may be properly revealed and check the feasibility of ESS setting method as well. Finally， an application example for large-scale real power system with the proposed method is given.
