This paper proposes a determination method of tuning parameters based on a High Speed Genetic Algorithm (HSGA) for a fuzzy type Load Frequency Control (LFC) in power systems. The proposed method avoids unnecessary computation of a conventional Genentic Algorithm (GA) to reduce the computing time and determinates tuning parameters of the fuzzy control used a phase plane. The principal features of the proposed method show the following:(1) It evaluates whether the individual is practiced the selection or not within the caluculation of the fitness. When the individual is practiced the selection, the computation of the fitness is closed at the point. (2) In case of the crossover, it evaluates whether the partial genes of crossover are identical or not. When the partial genes are jugeded the same it and the individual isn't done the mutation, the fitness is used it of the last generation.
To study the effectiveness of the proposed method, a 3-area longitudinal system is considered as a model system for the computer simulation.
