  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.
