The purpose of the EDISON WP3 workpackage is the development of a technical solution for intelligent system integration of distributed electric vehicles (EVs) plugged into an electric grid, in private homes or at charging stations in company and public parking lots.
The main challenge is a suitable aggregation technology for low-cost, efficient, plug-and-play integration of small-scale distributed energy resources (here EVs) into the power system. The technical solution is expected to benefit from the virtual power plant (VPP) technology that is currently being developed for microCHPs, as well as from ongoing demand-response (DR) activities that aim at standardizing interactions to shape power production and consumption.
The key issue is how to maintain security of supply in an electric grid that incorporates a high percentage of green, but fluctuating wind energy and also has a significant number of mobile EVs, which represent both a challenge and huge storage/regulation potential. To this end, active symbiotic integration is promoted. Moreover, both central and distributed control with grid DSO/TSO and market integration methods as suggested in EcoGridDK phase 2 will be investigated. For EV communication, the objective is to define a solution that gives the user a choice of aggregator and of the degree of grid-support service in order to analyze and enable various vehicle-to-grid (V2G) optimization plans.
The overall focus is on designing and prototyping a secure server solution to support the functioning of a wide-area intelligent system spanning geographical distance and various classes of intelligent devices potentially generating huge amounts of real-time data flows. While the initial prototyping will be tested and benchmarked in the Consortium laboratories, the goal is to facilitate the Bornholm island pilot and help in the assessment of full-scale Danish national plans in this space.
The key participants in EDISON WP3 are DTU Centre for Electric Technology and Informatics, and IBM.
