【摘要】：在含有分布式电源的微电网中,下垂控制会导致系统频率、电压偏离额定值,需要上层控制环节来消除偏差。然而分层控制中大多数控制策略都需要集中式的控制中心,对通信依赖度高,具有一定的局限性。文中结合微电网分层控制的基本框架,以实现每一层的分布式控制为目标,提出了基于多智能体一致性算法的分布式分层控制策略,以维持微电网系统频率和电压的稳定,以及实现有功、无功负荷在分布式电源间的灵活分配。文中提出的控制策略采用完全分布式的控制方法,在每一层控制中均不需要集中式的控制中心,适用于拓扑结构多变的微电网。最后,通过MATLAB/Simulink仿真平台验证了该控制策略的有效性。
[Abstract]:In the microgrid with distributed generation, droop control will lead to system frequency and voltage deviation from the rated value, which requires the upper control link to eliminate the deviation. However, most control strategies in hierarchical control require centralized control centers, which are highly dependent on communication and have some limitations. In this paper, a distributed hierarchical control strategy based on multi-agent consistency algorithm is proposed to maintain the stability of frequency and voltage of microgrid system, which is based on the basic framework of microgrid hierarchical control and the realization of distributed control in each layer. And to realize the flexible distribution of active and reactive power load between distributed power sources. The proposed control strategy uses a fully distributed control method, which does not require a centralized control center in each layer of control, and is suitable for microgrids with variable topology. Finally, the effectiveness of the control strategy is verified by MATLAB/Simulink simulation platform.
