Design and Implementation of Superconducting Fault Current Limiter in Power Distribution System for Energy Storage Protection
Abstract
Distributed Generation (DG) in the form of Renewable Power Generation systems is currently preferred for clean power generation. However due to their intermittent and unpredictable nature, energy storage needs to be used to ensure that the load is met at all times. Renewable distributed energy resources (DERs) will play a large role in the future energy infrastructure because of advantages like lower carbon imprints, lower fuel costs, and reduced power flows on transmission lines. Energy storage systems (ESSs) are enabling technologies for well-established and new applications such as power peak shaving, electric vehicles, integration of renewable energies, etc. The main objective of this project is to introduce a superconducting fault current limiter to keep the energy storage system from disconnecting the grid when ground faults occur.The possible advantages of Superconducting Fault Current Limiter (SFCL) as a means to limit the adverse effect of DG on distribution system protection and their effectiveness will be demonstrated. The SFCL has been noticed as the best solution to limit fault current effectively, which has continuously increased due to the expansion of the power facilities for the increased power demand. However, the application of the SFCL in the power system affects the protective coordination of the existing protective devices and can deviate their operation time from the original one. Therefore, the studies on the protective coordination considering the introduction of the SFCL are necessary prior to its installation. The simulation results are obtained using MATLAB/SIMULINK software.
