Electric Mobility - WG 2018-1

To limit CO2 emissions, many countries announced ambitious targets for the development of e-mobility (electric cars, buses, etc). The charging of these vehicles will create new loads with very specific characteristics and will have a significant impact on distribution networks. Smart charging solutions will be designed to minimize network congestions and limit reinforcement costs.
Hence, charging of Electric Vehicles (EVs) in an efficient and economical way will present new challenges for network planners.

The working group will investigate:

• How to forecast EV load profiles and charging stations load profiles (EV charging at home, in public areas, in collective residential building car parks, in office building car parks, etc) for network planning purposes
• How to assess the demand of a "smart house/building" (e.g. one with Photo-Voltaic generation on the roof, local storage, an EV and a home/building energy manager) and the total load of a group of such houses/buldings (Load diversity, impact of PV shading)
• How urban planning and traffic models can influence load profiles of fast and public charging stations
• Which EV load profilescould impact positively the distribution network, and in which cases
• How smart charging systems that limit charging demand in case of network
• Which new methods and tools will be needed by distribution network planners
