Experimental Studies on Power System Stabilization by Fuzzy Logic Switching Control of SMES Active and Reactive Power

Abstract

A Superconducting Magnetic Energy Storage (SMES) is proposed to be used the stabilizing control of power systems. By simulations, we have been studying its control effect, the required energy for power system stabilization, and so on. We have also proposed the power system stabilizing control by SMES incorporated with the fuzzy logic switching control. Recently, a systematically designed 50kJ SMES system is installed at Kumamoto University. We have investigated the stabilizing effect of the proposed fuzzy logic switching control by means of experiments with the SMES system and a one-machine infinite-bus system. In the pervious paper, the experimental results about the SMES active power control is mentioned. In this paper, the experimental results of a simultaneous control of the SMES active and reactive power, which is incorporated with the fuzzy logic switching strategy, are shown and discussed. We make clear the effect of power system stabilizing control incorporated with the fuzzy logic switching control by SMES.
