| Summary: | Charging–discharging coordination between electric vehicles and the power grid is gaining interest as a decarbonization tool and provider of ancillary services. In electric vehicle applications, the aggregator acts as the
intelligent mediator between the power grid and the vehicle. In recent years, researchers have introduced the
concepts of aggregated energy management, centralized-decentralized planning, and ideal charging–discharging
through improved technologies and integrated energy planning. These methods have the technical ability to
adapt the distribution network according to load, aggregator-controlled optimal charging–discharging, demand
management systems, strategic load assessments, and management. A comprehensive review suggests that largescale electric vehicle charging technologies for controlled charging–discharging is becoming a pitfall within the
grid and distribution network. This paper reviews several controlled charging–discharging issues with respect to
system performance, such as overloading, deteriorating power quality, and power loss. Thus, it highlights a new
approach in the form of multistage hierarchical controlled charging–discharging. The challenges and issues faced
by electric vehicle applications are also discussed from the aggregator's point of view. |
