Distributed Load Frequency Control for Multi-Area Power Systems

This paper investigates the distributed load frequency control problem for a class of multi-area power systems (MAPSs). Each agent in the MAPSs has the ability of information processing and learning, and there exists information interaction between the adjacent neighboring ones. A controller is designed to ensure the interconnected power system to be uniformly ultimately bounded (UUB) with a bounded mismatched load disturbance. Then, two decoupled conditions are derived so that the control gains can be obtained with only local information. Finally, some simulations are given to verify the correctness of the theoretical results.
