Smart home energy management system applied for smart electric vehicle charging and energy transaction

Abstract

Electric vehicles (EV), renewable generation sources and battery storage systems are important energy resources with great potential to impact the demand profile of electrical distribution networks. In this work, a new concept of residential electrical energy management system is presented, which in addition to managing the distributed energy resources present in the residence, also manages the EV charging, integrating three important concepts: mobile storage, V2G and energy transaction. For this, a management algorithm based on mixed integer linear program for real-time operation is developed. From the analyses carried out, the important contribution that the presented management concept can offer to the EV owner in relation to the profitability of its assets is observed. In addition, the presented approach has great potential to contribute to mitigating the negative impacts caused by the uncontrolled operation of the generation intermittent renewable energy and uncontrolled charging of the electric vehicle over the electrical distribution network.
