摘要
从信息物理设备交互影响的角度出发,将智能电网中的各微网类比为一个信息物理电力智能体,整个智能电网视为一个多智能体系统,根据分布式多智能体协同控制的相关理论,提出一种基于类比集群控制算法的协同控制策略,通过控制分布式储能设备作为调节功率的手段,能快速恢复故障系统的暂态稳定.最后,将控制策略应用在IEEE39 节点系统进行仿真验证,并在不同的最大输出容量的情况下,将稳定效果与另外三种控制器进行对比,仿真结果验证了所提控制策略能够在更短的时间内恢复系统的暂态稳定.
Abstract
From the perspective of the interaction and influence of cyber-physical devices,this paper compared each microgrid in the smart grid to a cyber-physical power agent,and the entire smart grid was regarded as a multi-a-gent system,according to the relevant theory of distributed multi-agent collaborative control,a collaborative control strategy based on the analogy cluster control algorithm was proposed,and the transient stability of the fault system could be quickly restored by controlling the distributed energy storage equipment as a means of regulating power.Fi-nally,the control strategy was applied to the IEEE39 node system for simulation experiment verification,and in the case of different maximum output capacity,the stabilization effect is compared with the other three controllers,and the simulation results verify that the control strategy proposed in this paper can restore the transient stability of the system in a shorter period of time.
