iZeus - Intelligent Zero Emission Urban Systems

The research project iZeus (Intelligent Zero Emission Urban Systems) aims to efficiently integrate mobile electrical storage in vehicles in the existing energy system by the use of innovative information and communication technologies and their implementation in coherent overall concept. For this purpose different scenarios regarding mobility behavior are investigated. These investigations are supposed to be carried out using simulations and particularly in a comprehensive fleet test.

The essential main areas of focus of the research are:
  • Value-added services for an experimental electric-vehicle fleet in the private as well as in commercial transport sector. This encompasses e.g. services like charging management based on economic and network oriented aspects, energy-efficient routing or a transport connection to other carriers in the context of a multimodal mobility management scheme.
  • A more profound connection of transportation and energy systems via the operational link of Smart Grid and Smart Traffic concepts.
  • The integration of (e.g. regional) renewable energy sources in the energy system. Thereby, the main focus is on the coordination of charging which should not only be oriented to economic criteria but also be aimed at a high share of electricity from renewable energy sources being used near real time to charge the electric-vehicles. Different mechanisms (technical approaches, economic incentives) are to be used for the implementation of charging coordination.
  • The further development of the legal framework to a secure and data protection compliant implementation of mechanisms and methods is developed during the project.

The research and demonstration laboratory which was established in the context of MeRegioMobil will stay an essential part of the investigations of new concepts. In particular, methods of technical design and evaluation of the local energy feed-in into the grid are to be developed, verified and tested. In addition to the technical aspects, all aspects which are important for people in an intelligently designed future of energy can be experienced in this habitable “Smart Home” and evaluated regarding their acceptance. Consortium leader of the project is the EnBW Energie Baden-Württemberg AG, supported on the part of the KIT by staff members of the institutes AIFB, IIP, IISM, ITM, ZAR, DSN und ITI.

abstract = {This work investigates the potential application of EV load
flexibility with respect to different coordination objectives. They include
individual cost or conventional generator use minimization, given volatile supply
from renewable sources. The evaluation shows that charging coordination can
generate savings and increase the direct utilization of renewable energy sources.
Allowing for resale of stored energy to the grid can further increase savings
but is limited by battery wear conditions.}}

abstract = {The Vehicle-to-Grid (V2G) concept is a promising possibility for
the integration of electric vehicles (EVs) into the power grid. This article
presents an economic evaluation of EVs participating in the ancillary service
market (primary, secondary and tertiary regulation) for the case of Germany,
based on a price data set from 2011 and 2012. We examine the economic potential
of nine general options to participate in the regulation market based on real-life
EV specifications, connection powers and regulation energy prices. Results show
that in the most profitable case a maximum average yearly profit of 730.31 €
per vehicle is possible for negative regulation with payment direction TSO to
provider in the secondary regulation market. Furthermore a sensitivity analysis
is performed for all of the analyzed participation scenarios in order to identify
crucial parameters for a possible V2G implementation. Major parameters for the
successful implementation of V2G are the provided power per vehicle, the time
an EV is available to the grid and the variable energy storage costs it incurs.}}
