Abstract:

The mathematical model of distribution network operation scheme was constructed. Based on it, a parallel evolutionary strategy combined self-adaption and multi-population was presented and implemented to optimize the distribution network opration scheme. Multiple populations were used to expand nodes in the network, and the corresponding cluster locations were evolved and variated progressively. Experimental results show that this strategy can greatly reduce the electric network loss and increase the economic benefit.

Key words: evolutionary strategies, parallel evolution, reconfiguration of electric networks
