SIMULTANEOUS COORDINATED TUNINGOF CES AND PSS FOR SINGLE-MACHINE USING GENETIC ALGORITHM

摘要

This paper presents a new coordinated design between Power System Stabilizer (PSS) and Capacitive Energy Storage (CES) using Genetic Algorithm (GA). A GA will determines optimal parameters for PSS and CES by tuning parameters PSS and CES simultaneously. The optimization results can change the value of PSS and CES parameters which can also cause oscillation on the system. This problem is formulated as an objective function with limits consisting of damping ratio and damping factor. The approach is succesfully tested on single-machines generator models. The optimization results show that this method is effective enough to damp the oscillation, so as to give an idea of the dynamic stability of the single-machine system.
