Intelligent integration of prosumers with battery energy storage in smart distribution systems using optimal design and a transactive energy framework
A legacy electric power distribution system is characterized by a unidirectional power flow from centralized power plants to customers. The role of these customers has been known for many years as power consumers and not power producers. In smart distribution systems, because of the widespread use …
