A Rule-Based Advanced Static Var Compensator Control Scheme for Transient Stability Improvement

The paper presents the application of a rule- based control scheme for an advanced static var compensator (asvc) to improve power system transient stability. the proposed method uses a current reference, based on the transient energy function (tef) approach. the proposed scheme provides, also, a continuous control of the reactive power flow. the performance of the proposed approach is compared with that of a system using a conventional control method and of a system without asvc. a single-machine system and an ieee three machine system are used to verify the performance of the proposed method.
