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.
