WP3: The purpose of the EDISON project is to use aggregators of electrical
vehicles (EV) including plug-in hybrid electric vehicles to provide the
required balancing power for increasing the usage of wind power in the Danish
electricity grid. The purpose of EDISON
Work Package 3 (WP3) is the development of a technical solution for intelligent
system integration of distributed EVs.
These may be plugged into the electricity grid at private homes, or at
charging stations in company or public parking lots.
Challenge: The main challenge is development
of a suitable aggregation technology for low-cost, efficient, plug-and-play
integration of small-scale distributed energy resources (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 electricity grid that incorporates a high
percentage of green, but fluctuating wind energy and that also has a significant
number of mobile EVs, which represent both a challenge and significant
storage/regulation potential. The objective of the EDISON
system is to provide benefit to both the grid and the users of the grid.
Both central and distributed control with
grid DSO/TSO and market integration methods, which are also being studied as
part of
EcoGrid,will be investigated. For EV
communication the objective is to define a solution that gives the user a
choice of aggregator and degree of grid-support services in order to analyze
and enable a range of vehicle-to-grid optimization plans.
Objectives: 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, and potentially generating large 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.
Report: This main EDISON WP3 public report
describes the architecture, the use of standards, the interfaces and
components, and the initial results from demonstration of the overall
environment. This system integrates EVs
and charging spots with the backend server, which plans the charging schedules
according to driving and grid requirements and market conditions.
Partners: The key participants in EDISON WP3
are DTU Centre for Electric Technology and Informatics, and
IBM Denmark and Research – Zurich.
Essential interactions with WP2, WP4, WP5, and WP6 are acknowledged.
