“双碳”目标下车-建筑-电网（VBG）协同互动的探索
Exploration of vehicle-building-grid (VBG) collaborative interaction under dual carbon target
摘要：
建筑是重要的电力终端用户，碳中和目标下将实现电力生产、消费、调蓄“三位一体”功能；汽车（特别是私家车）电动化是交通领域碳中和的重要举措，也有望成为未来电力系统中可利用的重要调蓄资源。建筑与电动车是重要的电力终端用户且有高度同步使用特征，二者协同起来可实现优势互补，由此能与电网实现良好互动。如何实现车-建筑-电网（VBG）之间的友好互动，如何充分发挥建筑、车作为电力系统灵活负载的资源潜力，如何有效调节、调度建筑、车与电力系统实现能量交互，是当前亟需回答的重要问题。本文对上述问题的相关研究进展进行了分析，并对未来需开展的研究进行了展望，以期为进一步深入研究、探索车-建筑-电网之间的协同互动提供参考。
Abstract：
Buildings are important end-users of electricity. Under the goal of carbon neutrality, the “trinity” of electricity production, consumption, regulation and storage will be realized. The electrification of vehicles (especially private cars) is an important measure for carbon neutrality in the transportation sector, and it is also expected to become an important regulation and storage resource available in the future power system. Buildings and electric vehicles are important end-users of electric power and have highly synchronous usage characteristics. When they work together, they can realize complementary advantages and achieve good interaction with the electric power system. How to realize the friendly interaction between vehicles, buildings and grids, how to give full play to the resources potential of buildings and vehicles as flexible loads of power systems, and how to effectively regulate and dispatch buildings, vehicles and power systems to achieve energy interaction are important questions that need to be answered. In this paper, the research progress of the above issues is analysed, and the future research that needs to be carried out is prospected, in order to provide a reference for further research and exploration of collaborative interaction between vehicles, buildings and grids.
