A Multi-Level Approach to the Target Development of the Electric Vehicle Charging Stations Network

Abstract

The paper proposes an approach to managing a charging stations network for electric vehicles based on a combination of their properties as car service systems and infrastructure objects of the transport network. Within the framework of the study, a functional model of the charging stations network management system was built according to the IDEF0 structural modeling standard. The developed model made it possible to determine the main parameters and indicators of the specified management system. The current state of the system determines its configuration within morphological constraints. The optimal configuration is the basis for determining the rational structure of the charging stations network at a given level of detail. The mathematical formulation of the problem of multi-criteria optimization of the network structure was performed. The specified mathematical model represents the charging stations network as a mass service system and takes into account the requirements for its functioning at three target levels: client, business, society. The structure of the demand for charging station services and the client radius are strong arguments for the appropriate objective functions. Other arguments of the objective functions are presented through the configuration of the management system. An algorithm for optimizing the structure of the charging stations network has been developed based on the proposed social efficiency indicator. The considered approach is recommended for use in the process of designing and developing charging station systems, as well as forecasting their performance.
