Abstract

A simple decentralized Kalman filter based regulator problem is proposed to achieve sub-system closed-loop eigenvalues at desired locations and subsequently to minimize the local quadratic performance index of each decoupled sub-system. The proposed scheme reduces the information exchange, telemetry and instrumentation costs and computational burden compared to a centralized control scheme. A consideration of the stability of the global decentralized control system is included. The effectiveness of the proposed control scheme is tested by considering a load-frequency control problem of a two-area power system.
