Control of interconnected power systems via linear programming and decentralized optimization techniques

Abstract

In this paper we consider the decentralized load-frequency control of a two-area power system. The model of the power system is determined, and is viewed as an interconnected system (A, B_d ), for which the methods of the decentralized control are applied: these are based on the intercontrollability matrix D(s), its kernel U(s) and the equivalent system {M(s), I₂ } in the operator domain. Afterwards, a decentralized control via linear programming methods, and with decentralized optimization techniques, is determined.
