Abstract: The proposed work is mainly about the study and analysis of load frequency control (LFC) of two area power system consisting thermal power plant and wind power plant. Output of wind plant connected in interconnected power system is regulated with help of Fuzzy Inference Technique. Three Adaptive Neuro-Fuzzy Inference System (ANFIS) controllers are used in proposed work. Gain of speed regulation is controlled by first ANFIS. Two Adaptive Neuro-Fuzzy Inference System’s are used to obtain control over the wind and thermal power plant gains. Inputs for FLC are obtained from change in frequency and derivative of change in frequency of interconnected power system. Fuzzy logic Controller (FLC) inputs are properly and carefully taken for obtaining control vector from defuzzified output of FLC. The output of self tuned FLC with all ANFIS’s in two plants are shown their performance under test conditions.
Keywords: Load Frequency Control, Interconnected Power System, Wind Power Plant, Fuzzy Logic Controller and Adaptive Neuro-Fuzzy Inference System.
