Abstract:The trend of intelligent and networked electric vehicles is driving the continuous integration of multi-party interaction centered on vehicle network interaction, which brings enormous pressure to the safe operation of the existing power grid. This article analyzes the influencing factors of the integrated operation capability of ev-pile-network-source under multi-party interaction from six aspects, and constructs an operation evaluation model based on this. Analyze the questionnaire survey data using Analytic Hierarchy Process, evaluate it using Fuzzy Comprehensive Evaluation Method, and identify the problems in the integrated operation of ev-pile-network-source. The research results indicate that the current integrated operation capability of ev-pile-network-source is at a general level, and the technological and innovative capabilities, as well as infrastructure construction capabilities, are relatively lacking, which needs to be focused on and improved; There is also significant room for improvement in operational capabilities. Finally, based on the research results, strategies are proposed to enhance the integrated operation capability of ev-pile-network-source in the construction of smart cities
