含再热和非再热机组，含模糊自适应PID控制器-This study presents an application of a fuzzy controller for load-frequency control of a two-area electrical interconnected power system. Model simulations of the power system show that the proposed　controller is effective and suitable for damping out oscillations resulted load perturbations.-This study presents an application of a fuzzy　controller for load-frequency control of a two-area electrical interconnected power system.
