Abstract

Abstract: The coordinated optimization of switches, tie lines and micro-grid connection point is a main method to narrow outage range, transfer loads and reduce outage cost when fault happens. The mathematic model of comprehensive optimization for distribution network is founded, which includes the cost of switches and tie lines along with user outage cost. The line segment is selected as basic unit in outage cost calculation. The comprehensive optimization is solved by co-evolutionary genetic algorithm. Key technologies and main flow of co-evolutionary genetic algorithm application are studied in distribution network comprehensive optimization. The economic comparison analysis results on IEEE33 node system and practical engineering projects distribution show the effectiveness of proposed algorithm.

Key words: tree distribution network, section switch, tie line, micro-grid, co-evolutionary genetic algorithm
