Research on Profit Analysis of E-NG Vehicle Charging Station Improved from Split Type into Joint Type

Motivated by the dual carbon goals, it is crucial to increase the impact of new energy vehicles to facilitate the transformation of the energy structure and to promote the advancement of energy cleanliness. New energy integrated charging stations serve as the energy integration hub for the automotive distribution infrastructure, and thus play a crucial role in promoting the proliferation of new energy vehicles. This study is focused on the multi-energy integration field and proposes a comprehensive energy station for new energy vehicles. This station takes into account the charging needs of mainstream new energy vehicles, integrates new energy power generation, and presents a station framework that employs two connection modes: joint and split. Based on this framework, the day-ahead economic scheduling optimization model is proposed, incorporating the time-of-use electricity price strategy and comprehensive consideration of new energy consumption. This model aims to reduce the operating cost of energy stations and promote the consumption of renewable energy. The case study demonstrates that the proposed optimal operation strategy can reduce the operating cost of the integrated energy station by 43.91%.
