Optimization of the Integrated Energy Management between Electric Vehicles and Building Energy

 

 

Optimization of the integrated energy management between electric vehicles and building energy

In the OKEE project, which analyses the optimal coupling of electric vehicles with (building) energy management systems in theory and practice, novatlantis is responsible for project initialisation, coordination of the project partners and communication.

The aim of the project is to research the networking and optimisation of the areas of electricity, heat supply and transport (so-called sector coupling) through pilot projects. The batteries of electric vehicles will be linked to the energy management system at building and area level thanks to bidirectional charging. It is expected that this will result in added value for the site operators (optimisation of PV own consumption), the fleet operators (new mobility concepts, e.g. EV car sharing) and the utility companies (new system services and higher local grid stability).

Launched in 2017, the project aims to set up and implement the first pilot projects in this area in Basel. The scientific work is being carried out by the ZHAW Institute for Sustainable Development.

Innovative implementation of a Vehicle-to-Home pilot project in Erlenmatt East

The Institute for Sustainable Development (INE) of the Zurich University of Applied Sciences (ZHAW) and novatlantis – the non-profit organisation for sustainability and knowledge transfer – are implementing the OKEE project for the integration of electric vehicles (EVs) into (building) energy management systems as part of the “Basel pilot region”.

The ADEV energy cooperative and the Habitat foundation are participating as innovative implementation partners, so that for the first time in Switzerland a complex Vehicle-to-Home (V2H) pilot project is combined with a car-sharing concept to increase the own consumption of photovoltaic electricity in an area developed according to the objectives of the 2000-watt society by using a mobile storage unit also stationary.

The implementation in Erlenmatt Ost in Basel from January 2018 is based on the common interest of all partners in the practical testing of charging and own consumption solutions for and with electric mobility in larger areas. To this end, charging stations, electric vehicles and a corresponding communication and control solution will be co-financed, installed, operated and scientifically monitored for one year in Erlenmatt Ost. In addition to the technical issues, the focus is on the development of organisational solutions (meter concepts, billing systems, measures to optimise own consumption and use of the mobile battery stationary for the power requirements of the superstructure). These solutions should be transferable to other areas in the future and thus make a major contribution to further applications in Basel and throughout Switzerland.

Background of the project

Experts expect the energy and mobility sector to grow together through the spread of electric vehicles. Batteries of electric vehicles are suitable for the intermediate storage of photovoltaic electricity and for increasing the internal consumption of single and multiple family homes or larger areas (Vehicle-to-Home, V2H) or for providing grid services by bundling battery capacities (Vehicle-to-Grid, V2G). The consortium has set itself the goal of implementing V2H and V2G solutions in Basel-Stadt. Particularly in the area of multi-family houses or residential areas, there are still many barriers to the implementation of these concepts: Due to tenancies, different planning horizons, high transaction costs or the lack of billing and metering concepts, own consumption and sustainable mobility solutions can only be realised by involving different actors and developing adapted solutions.
