Abstract:The trend of intelligent and networked electric vehicles is driving the continuous integration of multi-party interaction centered on vehicle network interaction, bringing enormous pressure to the existing power grid. In order to study the integrated operation capability of vehicle pile network source under multi-party interaction, this paper analyzes the influencing factors of the integrated operation capability of vehicle pile network source from six aspects, and based on this, constructs an evaluation model for the integrated operation of vehicle pile network source. Data is collected through questionnaire survey, and the fuzzy comprehensive evaluation method is used to comprehensively evaluate the integrated operation capability, and key improvement factors for improving the integrated operation capability of vehicle pile network source are identified. The research results indicate that the current integrated operation capability of vehicle pile network source is at a general level, and the technological and innovative capabilities, as well as infrastructure construction capabilities, are relatively lacking. It is necessary to focus on and improve these capabilities, and there is significant room for improvement in operational capabilities, which can be addressed at appropriate times. Finally, based on the research results, strategies are proposed to enhance the integrated operation capability of vehicle pile network source in the construction of smart cities.
