|Title:||Decentralised Load-frequency Control|
|Abstract:||We propose a numerical procedure to determine the load-frequency control of a power system composed of several interconnected areas. In order to decrease the associated implementation cost, the control law is constrained to have two different special structures: decentralized feedback and/or output feedback control. The procedure is based on a new property of the classical Raccati equation which is analyzed in two different aspects: closed-loop asymptotic stability and suboptimality degree. An example of two interconnected areas is solved and comparisons are made in order to evaluate the performance of the closed-loop system.|
