    This paper presents new algorithm "AVSS-HSGA" for optimization problems. The proposed method is a technique that the search space of Genetic Algorithm (GA) can change as the need arises. And it is possible to obtain the higher-fitness answer easily than the conventional Genetic Algorithm by introduced the technique. It is applied to optimum design of the multi-input PSS in power system, which contains low-frequency oscillations, and the validity of the proposed method is compared with the conventional GA. © 2001 IEEE.

    Multi-input PSS (P+ω+Q type PSS) using the three input signals(P, ω Q) which it is more excellent than the conventional PSS is developed. In this paper, the design method of multi-input PSS which uses the high speed genetic algorithm (HSGA) is proposed. This method realizes the high-efficient design of parameters of multi-input PSS. The high stability of the designed PSS is proven in the simulation that uses a three-machine seven-bus low-frequency oscillation power system model.
