AB  - The fast variations of wind speed during extreme wind gusts result in fluctuations in both generated power and the voltage of power systems connected to wind energy conversion system (WECS). This paper presents a control strategy which has been tested out using two scenarios of wind gusts. The strategy is based on active and reactive powers controls of superconducting magnetic energy storage (SMES). The WECS includes squirrel cage induction generator (SCIG) with shunt connected capacitor bank to improve the power factor. The SMES system consists of step down transformer, power conditioning unit, DC-DC chopper, and large inductance superconducting coil. The WECS and SMES are connected at the point of common coupling (PCC). Fuzzy logic controller (FLC) is used with the DC-DC chopper to control the power transfer between the grid and SMES coil. The FLC is designed so that the SMES can absorb/deliver active power from/to the power system. Moreover, reactive power is controlled to regulate the voltage profile of PCC. Two inputs are applied to the FLC; the wind speed and SMES current to control the amount active and reactive power generated by SMES. The proposed strategy is simulated in MATLAB/Simulink®. The proposed control strategy of SMES is robust, as it successfully controlled the PCC voltage, active and reactive powers during normal wind speeds and for different scenarios of wind gusts. The PCC voltage was regulated at 1.0 pu for the two studied scenarios of wind gusts. The fluctuation ranges of real power delivered to the grid were decreased by 53.1% for Scenario #1 and 56.53% for Scenario #2. The average reactive power supplied by the grid to the wind farm were decreased by 27.45% for Scenario #1 and 31.13% for Scenario #2. © 2016 Elsevier Ltd. All rights reserved.

AB  - This paper presents the impacts superconducting magnetic energy storage (SMES) in suppressing the voltage sag/swell in distribution systems with wind power penetration. Wind turbine used in this paper is of squirrel cage induction generator (SCIG) with shunt connected capacitor bank to improve the power factor. SMES system consists of step down transformer, power conditioning system, DC-DC chopper, and large inductance superconducting coil. Wind energy generation system (WEGS) and SMES system connected to the grid at the same bus to achieve high performance. Fuzzy logic controller (FLC) used for DC-DC chopper to control in power transfer between the grid and SMES coil. The FLC is designed so that the SMES can absorb/deliver active power from/to the distribution system. On the other hand, reactive power can be delivered/absorbed to/from the distribution system according to the voltage difference between the SMES voltage and DC link voltage. Two inputs were applied to the FLC; bus voltage and SMES current variations. This technique of two inputs was proved to enhance the control performance. Detailed simulation is carried out using Matlab/Simulink and Simpowersystem package. © 2014 IEEE.
