A Coordinated Charging Strategy for Users in Old Residential Communities Considering Price Incentive

Due to limited electrical capacity and insufficient parking spaces, electric vehicle (EV) charging in old residential communities (ORCs) is restricted, significantly affecting residents' quality of life and hindering urban sustainability. Given economic and social factors, ORCs will likely persist globally in the foreseeable future. To address these challenges, a dynamic pricing-based coordinated charging strategy for establishing shared DC fast-charging stations has been designed to guide users in selecting initial charging times. This strategy aims to reduce operators' electricity purchase costs and users' charging expenses while improving the utilization of EV charging infrastructure. The approach is driven by human demand and integrates behavioral surveys related to charging station locations and times. A case study based on a real ORC in Shenzhen, China, demonstrates that dynamic pricing effectively guides users to adjust their charging behavior, resulting in peak shaving and load leveling on the demand curve.
