Description

technical field [0001] The invention relates to the field of electric power systems, in particular to an optimization operation analysis technology for distribution network reconfiguration. Background technique [0002] The analysis and optimization of distribution network has always been one of the research hotspots in the field of power system, and distribution network reconfiguration is an important means to optimize the operation of power system, and it is also an important part of distribution automation system. The distribution network is usually a closed-loop design and open-loop operation. The network contains a large number of section switches and a small number of tie switches. The distribution network reconstruction is to ensure the constraints of line voltage and current, feeder heat capacity, and network radial operation. Under certain conditions, the topological structure of the distribution network is adjusted by changing the switch combination state in the ne...
