Abstract
This paper deals with a decentralized hierarchical control of power networks by using overlapping information. The control objective is to minimize the cost function of load frequency control problem. The control law is constructed through three steps. In the 1st step, we make a hierarchical system with overlapping information. In the 2nd step, a relationship between the original system and the hierarchical system is confirmed. In the 3rd step, the hierarchical decentralized control for the hierarchical system is constructed and the decentralized hierarchical control law is contracted to the original system. Then, we show the effectiveness of the load frequency control by using the proposed control method.
