Abstract

A fuzzy power system stabiliser (FPSS) is developed using the concept of fuzzy basis functions. The linguistic rules, regarding the dependence of the plant output on the controlling signal, are used to build the initial FPSS. Based on the Lyapunov´s direct method, an adaptation rule is developed in order to make the FPSS adaptive to changes in operating conditions of the power system. The FPSS is designed for a cogenerator, and simulation studies are based on a one machine-infinite bus model. Nonlinear simulations reveal that the performance of the adaptive fuzzy power system stabiliser (AFPSS) is better than the performance of a conventional (linear) power system stabiliser (CPSS) and a fixed-parameter FPSS for a wide range of operating conditions
