Abstract

Distribution network loss is influenced by many factors and it is necessary to identify the key influencing factors so that the energy-saving transformation of distribution network will be more targeted.The relevancy between the main loss influence factor and line loss rate of the distribution network is analyzed by the use of classic gray correlation which is subject to varied weight processing of AHP（analytic hierarchy process）method

the key energy-consumption sectors is taken out and the load reduction measures for the key energy-consumption sector are adopted. With the direct and indirect loss reduction caused by the loss of the modified transformer and line at least as objective function and with consideration of such constraint condition as total investment

operation reliability and safety etc

the model for loss reduction and optimization is set up. The strategy model is solved by the method of exhaustion. Various combination schemes of loss reduction measures are listed. The load reduction efficiency of each scheme is calculated and compared. Finally

the effectiveness and practicability of the method proposed in this paper is verified by the cost of a numerical example.
