Voltage and Frequency Control of Balanced/Unbalanced Distribution System Using the SMES System in the Presence of Wind Energy

This paper presents an effective solution to overcome the problem caused by intermittent energy sources that are connected a balanced/unbalanced distribution system using superconducting magnetic storage (SMES) mitigating voltage and frequency fluctuations during wind gusts. The fuzzy logic control technique (FLC) is used with SMES improve frequency. A squirrel cage induction generator (SCIG) applied as generator. IEEE 33-bus validate proposed method. Buses 18 33 weakest points in this system; thus, systems at these buses. We MATLAB/Simulink simulate performance of (balanced/unbalanced) considering SMES, system, (FLC). simulation results show high method alleviate fluctuation achieve power leveling strategy studied system.
