Abstract
The fast response, high efficiency and long lifetime of superconducting magnetic energy storage (SMES) compared to other energy storage systems make it a preferable selection for energy storage solution for wind power generation. SMES has attracted many researchers to study its potential applications in power systems. This paper discusses a scheme of fuzzy logic controlled SMES to minimize the voltage fluctuations of three-phase unbalanced radial distribution systems connected to wind energy conversion system (WECS) with large scale penetration level of 30% during wind speed gusts. In this paper, wind turbine used is of squirrel cage induction generator (SCIG) with shunt connected capacitor bank for power factor improvement. SMES unit consists of superconducting coil, DC-DC chopper, step down transformer, power conditioning system, and cryostat/vacuum vessel. The control technique is based on fuzzy logic controller (FLC). The studied system is 33-bus three-phase unbalanced radial distribution system. The SMES and WECS were connected to weakest buses in the system, namely Buses18 and 33. The control strategy is discussed in details and the proposed system is evaluated by simulation in MATLAB/SIMULINK package. The simulation results demonstrate the performance of the proposed fuzzy-logic-controlled SMES in mitigating the voltage fluctuations under wind speed gusts.
