Optimization of Resistive Superconducting Fault Current Limiter Considering Protection Coordination in Medium-Voltage Distribution Networks
摘要
Abstract
The integration of distributed generation(DG)has significantly improved the utilization efficiency of renewable energy sources,but it has also posed new challenges to the safe and stable operation of medium-voltage distribution networks,especially regarding the reliable operation of protection devices.The resistive superconducting fault current limiter(RSFCL)can effectively control the abnormal growth of current and solve the above problems through coordinated operation with protection devices.The 10 kV distribution network is focused on and the optimal configuration of RSFCL is investigated.The impact of DG integration on current protection is analyzed,the corresponding mathematical model is constructed,and the superconducting fault current limiter is incorporated into the model to limit the growth of current.Furthermore,a pre-selection scheme for the installation location of the current limiter based on sensitivity analysis is proposed to address the optimal configuration problem under the scenario of multi-point DG integration and the peafowl optimization algorithm is used to solve the optimal configuration of the current limiter.The simulation results verify the effectiveness of the proposed configuration scheme in solving the problem in this scenario.关键词
