Abstract: In order to optimize the design of superconducting fault current limiters(SFCLs),this paper presents an improved algorithm for multi-objective optimization design for electrical power grids.Firstly,a numerical model of resistive-type SFCL based on MATLAB and PSCAD/EMTDC is built and its accuracy is verified by the finite element method(FEM)model.Then a numerical model of distribution network in Shanghai City is built.Simulations considering different types of short-circuit fault in the real distribution network are carried out to get the optimized function.Different initial phase angles are also taken into account.Finally,the optimizing parameters of SFCL are determined by considering three optimized objectives and four constraints.The simulation results show that the optimized SFCL can limit short circuit current effectively without any influence on the performance of the power grid.
