Designing a Transactive Electric Vehicle Agent with Customer's Participation Preference

TL;DR

This paper introduces a transactive EV agent that balances customer preferences for savings and vehicle readiness, integrating privacy-preserving bidding and market mechanisms to enhance grid performance and customer autonomy.

Contribution

It presents a novel transactive EV agent with a customer-controlled slider for trade-offs and a privacy-preserving bidding formulation, integrating into local markets.

Findings

The slider effectively balances savings and vehicle readiness preferences.

Market mechanism reduces peak prices and demand.

Abstract

The proliferation of electric vehicles (EVs) and their inherent flexibility in charging timings make them an asset to improve grid performance. In contrast to direct control by a utility or autonomous price-based charging, the transactive control framework not only provides benefits to both grid and customers but also ensures customer autonomy. In this work, we design a transactive electric vehicle (TEV) agent that incorporates the EV owner's willingness to trade-off between savings and amenity in form of a slider, where the EV owner's amenity is characterized as vehicle readiness. Further, a privacy-preserving bidding formulation is proposed that also represents the customer's transactive preference. A transactive market mechanism is discussed that integrates the TEV Agents into the local retail market and reconciles with the current day-ahead and real-time market structure. It is demonstrated that the proposed slider is able to provide a preferred trade-off between savings and amenity to individual customers. At the same time, the market mechanism is shown to successfully reduce both peak prices and peak demand. A comparative investigation of V1G and V2G technologies with respect to the battery prices is also discussed.
