Abstract

A method for evaluating the comprehensive performance of electric vehicle fast charging facilities of the invention comprises the following steps: collecting comprehensive performance index data; calculating an index weight set; determining the membership according to a trapezoidal membership function and expert scoring; determining a quantitative index fuzzy evaluation vector according to the membership function and index weights; determining a fuzzy comprehensive evaluation value; and determining the evaluation grade of the comprehensive performance of electric vehicle fast charging facilities according to an evaluation value grading standard and the fuzzy comprehensive evaluation value. The comprehensive performance evaluation method put forward by the invention provides detailed reference and guidance for planning construction and operation management of electric vehicle fast charging facilities.

Description

technical field [0001] The invention relates to the field of charging and replacing electric vehicles, in particular to a method for evaluating the comprehensive performance of fast charging facilities for electric vehicles. Background technique [0002] The popularization of electric vehicles is an important way to realize the low-carbon development of transportation in the future. According to the research report on the development strategy of electric vehicles issued by the Ministry of Industry and Information Technology, it is estimated that by 2030, the number of electric vehicles in my country will reach 60 million, and the total Power consumption is expected to be as high as 135 billion kWh, accounting for about 1.3% of the country's electricity consumption. Such a large-scale access to electric vehicles will undoubtedly test the safety of some weak links in the power system. Inspired by measures such as electricity prices, electric vehicles can adopt charging modes su...
