چکیده
Automatic generation control in electric power system design is a major concern nowadays due to its rising size, varying structure, integration of renewable-energy sources and distributed generators to meet the growing demand. In this paper, automatic generation control of an interconnected four area hydro thermal system examined. Each area equipped with reheat turbine for thermal system and hydro turbine with electric governor for hydro system. Load frequency stabilization gained by including Superconducting Magnetic Energy Storage system (SMES) in all areas. A comparative analysis made between Proportional and Integral (PI) controller with Fuzzy Logic controller with and without including SMES in the four area power system. The designed Fuzzy Logic Controller can generate best dynamic performance for step load perturbations given in all areas. The system simulation realized by using MATLAB software. KeywordAutomatic Generation Control, Frequency deviation, Fuzzy Logic Controller, Proportional Integral Controller, Superconducting Magnetic Energy Storage system.
