Abstract:It is difficult for distributed charging and battery swapping facilities to meet the rapidly growing demand because of problems such as small charging power, complex scheduling relationships, and low spatial intensity. Centralized EV charging and battery swapping facilities (CCSF) with a unified dispatching body, clear dispatching relationships, and centralized communication and management and control capabilities have become an inevitable choice. This paper first introduces the development background and typical applicable scenarios of CCSF, elaborates the typical EV load demand simulation method, and summarizes the typical CCSF research status, structural composition and mathematical model. Secondly, it analyzes the planning research status of CCSF from the aspects of independent planning and power grid collaborative planning considering CCSF and power grid-traffic network collaborative planning. Then it summarizes optimal operation research status of CCSF in orderly charging strategy, intelligent charging path guidance, and power grid collaborative dispatch considering CCSF. Finally, combined with the CCSF existing research bottleneck, the future research directions are prospected. Overall, CCSF can meet the rapid energy replenishment needs of EVs, and has the advantages of promoting new energy consumption, improving power grid carrying capacity, realizing charging load orderly management, reducing the influence of individual difference, improving system operating efficiency, and promoting system low-carbon transformation.
