摘要
针对电力系统中多种控制器间参数配合不合理的问题,结合电力系统低频振荡的抑制问题,对电力系统稳定器(PSS)与储能装置的协调优化进行研究。基于电力系统分析综合程序(PSASP),分析PSS、储能装置的控制逻辑,并基于PSASP的用户自定义模块搭建储能装置控制模型。针对PSS与储能装置对应的参数优化模型,利用细菌群体趋药性(BCC)算法,进行PSS和储能控制器的参数优化分析。以四机两区系统模型为例对协调优化方法进行验证,特征值分析结果及时域仿真测试结果表明,经协调优化后的控制器参数能够有效抑制低频振荡,提高电力系统动态稳定性。
Aiming at solving the problem of the unreasonable parameter coordination between various controllers in power system,this paper studies the coordinated optimization of PSS and energy storage device,combined with the suppression of low-frequency oscillation of power system.Based on PSASP,the control logic of PSS and energy storage device is analyzed,and the control model of energy storage device is built based on the user-defined module of PSASP.The coordinated control strategy between PSS and energy storage device was studied,and the corresponding parameter optimization model was established.The Bacterial Colony Chemotaxis(BCC)algorithm was used to optimize the parameters of PSS and energy storage controllers.Cases study based on two-area with four-machine system shows that the coordinated controller parameters can effectively suppress low-frequency oscillation and improve the dynamic stability of the power system.
