Comprehensive benefit evaluation method of reactive power compensation device based on fuzzy comprehensive evaluation method

Abstract

The invention discloses a comprehensive benefit evaluation method of a reactive power compensation device based on the fuzzy comprehensive evaluation method. The method comprises the steps of establishing a comprehensive benefit evaluation index system of the reactive power compensation device in a power transmission and distribution system; determining n to-be-evaluated configuration schemes for the reactive power compensation device among the nodes of the power transmission and distribution system, collecting evaluation indexes and subjecting the evaluation indexes to hierarchical reduction; conducting the normalization treatment; making indexes being dimensionless; conducting the comprehensive weighting method to determine a comprehensive weight for the above dimensionless evaluation indexes; and subjecting the above to-be-evaluated configuration schemes for the reactive power compensation device to comprehensive evaluation based on the fuzzy comprehensive evaluation method. According to the technical scheme of the invention, the application comprehensive benefits of different types of reactive power compensation devices in the power transmission and distribution system are measured and calculated. In this way, a scientific decision basis is provided for the reactive power investment of all market participants. Meanwhile, the planning and the constructing of the reactive power compensation device can be effectively guided. Therefore, the optimized utilization of reactive power sources on the power grid side can be realized.
