摘要

针对极端灾害导致的多个调频单元不能有效协同调频和异质调频单元难以协同调频的问题,提出基于多智能体的分布式一致性协同自动发电控制（AGC）方法。首先,为实现多个调频单元协同参与二次调频,构建分布式一致性多源协同AGC框架。其次,基于分布式一致性理论和各调频单元的动态运行特性,提出一种基于分布式一致性的区域控制误差（ACE）发掘算法。然后,各调频单元基于发掘的所在区域ACE信号,通过设计的独立PI控制器参与调频。最后,在调频后半段通过调节响应速度较慢调频单元的输出功率,释放响应速度较快调频单元的频率响应能力,为下一轮频率调节预留调频容量。通过在Matlab/Simulink中搭建微电网仿真模型验证可得所提AGC方法能够有效协同异质调频单元参与调频,且在极端灾害下有较强的抗干扰能力。

Abstract

To address the problems that multiple frequency-regulation units cannot effectively coordinate frequency regulation under extreme disasters and that heterogeneous frequency-regulation units are difficult to coordinate, this paper proposes a multi-agent-based distributed consensus cooperative automatic generation control （AGC） method. Firstly, a distributed consensus-based multi-source cooperative AGC framework is established to enable multiple frequency-regulation units to participate collaboratively in secondary frequency regulation. Secondly, according to distributed consensus theory and the dynamic operating characteristics of different frequency-regulation units, a distributed consensus-based area control error （ACE） estimation algorithm is proposed. Then, each frequency-regulation unit participates in frequency regulation through an independently designed PI controller according to the estimated ACE signal of its area. Finally, in the later stage of frequency regulation, the output power of frequency-regulation units with relatively slow response speeds is adjusted to release the frequency-response capability of units with faster response speeds, thereby reserving frequency-regulation capacity for the next regulation cycle. A microgrid simulation model is built in Matlab/Simulink, and the simulation results show that the proposed AGC method can effectively coordinate heterogeneous frequency-regulation units for frequency regulation and exhibits strong disturbance rejection capability under extreme disasters.
