Second degree generalized gauss-Seidel iteration method for solving linear system of equations

Abstract

The main objective of Automatic Generation Control (AGC) is to balance the total system generation against system load and losses so that the desired frequency and power interchange with neighbouring systems are maintained. Any mismatch between generation and demand causes the system frequency to deviate from its nominal value. Thus the high frequency deviation may lead to system collapse. Therefore, it is necessary to include the active controller as Superconducting Magnetic Energy Storage Units (SMES) to maintain the nominal system frequency. This paper presents the application of energy storage units in an interconnected two area hydropower system. The proposed work consist of two area interconnected hydro power system with Superconducting Magnetic Energy Storage units has been designed to improve the dynamic performance of the system and also Integral Square Error (ISE) technique is used to obtain the optimal integral gain settings. The simulation result shows that the Load Frequency Control in an interconnected hydro power system with SMES units is considerably improved the system dynamics such as peak overshoot, settling time and frequency oscillation as compared to that of the system without SMES units. The system simulation realized by using MATLAB software.
