Inappropriate configuration of reactive compensation devices in 10 kV lines usually leads to excessive distance of reactive current flow,increased network loss and reduced supply voltage quality.The present work studied a modified-ge-netic-algorithm-based method to optimally configure reactive compensation devices.The method works through saliently the calculation of optimal installation locations and capacities via a real-coded genetic algorithm,in which the objective and the constraint are minimum annual line loss rate and qualified line voltage,respectively.Simulation on a case model built based on structure and actual operation data of a regional distribution network in Beijing verified tentatively the effective-ness of the proposed method in configuring reactive compensation,which is manifested by reduced system investment and operation loss,and improved quality of electric supply.
