A novel load - frequency control scheme applying fuzzy logic technique for twoarea interconnected power systems with renewable energy sources

Abstract

This paper proposes a novel intelligent control algorithm in dealing with the load-frequency control problem of a two-area interconnected
thermal power system. This control methodology applying a modified PID controller with three parameters tuned by a reasonable fuzzy logic
inference structure. The control plant of this study is a two - area interconnected electric thermal power grid model using reheat and nonreheat turbines together with renewable energy sources such as wind power and solar energy. This model is mathematically established at
first and the load-frequency control solution employing the proposed fuzzy logic-based PID controllers is implemented successfully in
MATLAB/Simulink environment. The numerical simulation results obtained in various scenarios compared with those of the conventional
regulators and a number of existed intelligent load-frequency counterparts demonstrate the high effectiveness and applicability of the proposed control strategy
