Integration of Prosumers with Battery Storage and Electric Vehicles via Transactive Energy

This paper presents a novel transactive energy approach that uses the utility's distributed energy management system, the home energy management systems in the residential customers and the existing inter-communication infrastructure to: 1) enable the electric utilities to identify the negative impacts of integrating local distributed energy resources (such as rooftop solar photovoltaic) and electric vehicles; 2) provide voltage support, transformer management and phase balancing to mitigate such impacts (utilities objectives); and 3) create a day-ahead local energy market whose participants are the homeowners with home battery storage. In this market, the homeowners compete among each other through a dynamic Bertrand game to maximize their payoffs (customer's preferences). The results have demonstrated the capability of the proposed transactive energy approach to resolve the conflicting objectives between the utility and the customers by improving the service voltage, extending the lifetime of the transformers, and reducing the voltage unbalance, while increasing the profits for the homeowners through the energy arbitrage without sacrificing the homeowner's convenience.
