Optimal Model for Prosumer Remuneration Schemes Considering Electric Vehicle Chargers Coordination

Abstract

The increasing presence of decentralised power generation and storage in modern grids has led to the development of new agents and interactions. In particular, consumers that have the potential of exploiting flexibility, can interact with the physical grid itself or through aggregators that bridge the gap between these ends users and traditional centralised markets. This paper aims to provide an insight on the benefits for both aggregators and end-users from a financial standpoint. The considered end-users can provide flexibility capacity from electric vehicle chargers and battery storage. We analyse different levels of remuneration for end-users, the difference when no intermediate party is present, and we conclude about the most advantageous set-ups for both aggregators and end-users. The results numerically show that some consumers can benefit more when aggregated, which depends on their behaviour and specific available flexibility, while others don’t seem to have an advantageous position when intermediate parties are present.
