Abstract
This paper presents an effective solution to overcome the problem caused by intermittent energy sources that are connected to a balanced/unbalanced distribution system using a superconducting magnetic energy storage (SMES) system by mitigating the voltage and frequency fluctuations during wind gusts. The fuzzy logic control technique (FLC) is used with SMES to improve the voltage and frequency. A squirrel cage induction generator (SCIG) is applied as the wind energy generator. The IEEE 33-bus distribution system is used to validate the proposed method. Buses 18 33 are the weakest points in this system; thus, the wind and SMES systems are connected to the system at these buses. We used MATLAB/Simulink to simulate the performance of the IEEE 33-bus system (balanced/unbalanced) considering the SMES, wind system, and fuzzy logic control (FLC). The simulation results show the high performance of the proposed control method to alleviate the voltage and frequency fluctuation and achieve the power leveling strategy of the studied system.
Highlights
Due to the significant benefits, such as the reduction of fossil fuel consumption and CO2 emissions, ensuring environmental cleanness, preserving rural areas, covering the load demand, and the long operation period, renewable energy sources (RESs) have become the favorable choice to generate electricity in many countries
This paper proposes a control method based on fuzzy logic controller (FLC)-superconducting magnetic energy storage (SMES) to mitigate the severe changes in the frequency, power, and voltage caused by wind gusts with 30% penetration of the total load connected to the IEEE 33-bus balanced/unbalanced distribution system for controlling the active and reactive power injected into the system
The SMES unit is a type of RES that depends on storing the energy in magnetic form
Summary
Due to the significant benefits, such as the reduction of fossil fuel consumption and CO2 emissions, ensuring environmental cleanness, preserving rural areas, covering the load demand, and the long operation period, renewable energy sources (RESs) have become the favorable choice to generate electricity in many countries. This paper proposes a control method based on FLC-SMES to mitigate the severe changes in the frequency, power, and voltage caused by wind gusts with 30% penetration of the total load connected to the IEEE 33-bus balanced/unbalanced distribution system for controlling the active and reactive power injected into the system. The simulation results prove the efficacy of the proposed control method with SMES to alleviate the voltage and frequency fluctuation for the duration of wind gusts in balanced and unbalanced cases.
