Transactive control mechanism for efficient management of EVs charging in transactive energy environment

This paper introduces a transactive energy (TE) approach through a transactive control (TC) mechanism for efficient electric vehicle (EV)-grid integration and management with the goal of minimizing the charging cost of EVs and mitigating the adverse effects on the grid. Charging EVs can present undesirable effects, e.g., overload components, in the distribution systems. In the proposed TE+TC approach, the distribution system operator (DSO) generates a distribution locational marginal price (DLMP) for the transactive nodes (TNs) which is then sent to each customer's house, assuming that the TN and the customers have local agents. Based on their needs and the received transactive incentive signal (TIS), consumers will determine their EVs charging hours. Upon execution, the consumer sends the information back to the transformer as a transactive feedback signal (TFS). This information allows the DSO to recalculate its TIS at the TN and adjust the new demand pattern accordingly. In order to evaluate the effectiveness of the proposed TE+TC approach, this paper considers a case study of a transformer located at a 6-bus distribution feeder test system.
