Scope

Scope: This document specifies the evaluation content and indicators of the safety, reliability, adequacy, and power demand response capabilities of the grid-connected technology solutions for electric vehicle charging and swapping stations. This document is applicable to charging and swapping stations that are connected to public power grids with voltage levels of 110 kV and below, have a distribution capacity of not less than 100 kVA, and have a number of charging equipment of not less than 3 units. Main technical content: Electric vehicles are an important carrier for the energy Internet to achieve energy substitution and clean substitution. The planning and layout of electric vehicle charging and swapping stations is closely related to the current and future development trends of local economic development, traffic density, charging demand, urban development planning, road network planning, and the construction of power transmission and distribution networks. The emergence of many uncertainties makes the scientific planning and layout of electric vehicle charging and swapping stations very complex and difficult. At the same time, electric vehicle charging and swapping stations, as a typical flexible load, will be a potential flexible adjustment resource for the grid under the effect of large-scale aggregation. Therefore, how to combine the uncertainties of the external environment with the planning and construction of electric vehicle charging and swapping stations, meet the charging needs of electric vehicles, and fully explore the aggregation effect and potential adjustment capacity of electric vehicle charging and swapping stations, and strengthen the deep integration and coordinated development of electric vehicle charging and swapping stations with the grid has become an outstanding problem that urgently needs to be solved.
