Abstract :
In this paper, the AGC improvement of a two area interconnected hydrothermal system along with a Superconducting Magnetic Energy Storage is proposed. Generation Rate Constraints are also considered. Integral Squared Error technique is used to obtain the optimum values of the integral gain settings. Analysis reveals that the dynamic responses are considerably improved in the presence of the SMES unit. A comparison and analysis of the dynamic performances without and with SMES unit in the presence of GRC brings out the superior performance of the SMES unit in suppressing the frequency and inter-area tie-power deviations from their nominal values followed by a step load perturbation.
