Planning-demand-considered comprehensive evaluation method for communication mode of cluster management system of charging piles of electric automobile

Abstract

The invention provides a planning-demand-considered comprehensive evaluation method for a communication mode of a cluster management system of charging piles of an electric automobile. The method is characterized in that an evaluation index system for the communication mode of the cluster management system of the charging piles is established according to the economy, the technicality and the applicability; a cloud model is utilized for expressing qualitative evaluation comments as well as reflecting the ambiguity and randomness of the evaluation comments; a comprehensive cloud model is calculated according to the combination of a plurality of groups of evaluation comments; the quantitative conversion of the qualitative indexes is achieved according to the maximum cloud similarity principle; the planning demand factors of a charging station are introduced to each index so as to enable the comprehensive evaluation result is more realistic; finally, the planning-demand-considered grey comprehensive evaluation method is performed to achieve the comprehensive evaluation. The method shows high adaptability for different cluster environments, is relatively high in practical value and is of a certain reference significance for the construction of a communication network of the cluster management system of the charging piles.

Description

Technical field: [0001] The invention relates to the field of evaluation of communication modes, in particular to a method for comprehensive evaluation of communication modes of an electric vehicle charging pile cluster management system considering planning requirements. Background technique: [0002] The smooth interaction of information between the electric vehicle (EV) charging pile cluster and the system operation and maintenance, monitoring and management center is one of the key factors to improve service efficiency and reduce operating costs. At present, research on electric vehicle charging stations at home and abroad mainly focuses on modeling, layout planning, and economic operation strategy analysis. However, the research on the underlying communication networking scheme of the charging pile cluster management system is still incomplete. The networking scheme still lacks uniform standards and has strong diversity. Almost all upper-level applications and requirem...
