配电网络电能质量综合治理设备优化配置策略OA北大核心

Aimed at the problem that the power quality control equipment in distribution network is lack of collab-orative allocation,an optimal allocation strategy for the control equipment of harmonics,reactive power and three-phase imbalance is proposed,which is based on the multi-objective particle swarm optimization(MOPSO)algorithm.The active power filter(APF)is used to suppress harmonics,the intelligent capacitor is used to compensate reactive power,and the phase-change switch is used to reduce three-phase imbalance.The control effect and operating cost about each power quality issue are taken as optimization objects,and the relevant power quality standards are considered as constraints.Through the MOPSO algorithm,an optimal allocation scheme for the allocation nodes and relevant access capacity of control equipment can be obtained.Furthermore,a power quality assessment model is built,and a simulation model based on an improved IEEE 18-node distribution system is also constructed.The harmonics,reactive power and three-phase imbalance loads are separately connected to simulate power quality issues,and simulation results verify the feasibility of the proposed strategy and its advantages compared with the tradi-tional scheme for power quality control equipment.
