An innovation project by the University of Applied Sciences Northwestern Switzerland FHNW and the OST - Ostschweizer Fachhochschule shows for the first time how car-sharing fleets can contribute to grid stabilization as flexible energy storage systems. Together with the energy suppliers AEM, ewz and Primeo Energie as well as the Mobility Cooperative, they investigated how bidirectional charging can be integrated into existing electricity grids in a technically and economically viable way. The conclusion: bidirectional charging electric cars are a practicable and worthwhile building block for the energy transition - both for grid operators and for vehicle fleet operators.<\/p>\n

From car to active network participant<\/strong><\/h3>\n

The core question of the project was: Can electric vehicles not only draw electricity from the grid, but also feed it back into the grid in a targeted manner - and thus reduce the load on the power grid? The answer is yes - and not just in theory. In several real field tests, Mobility vehicles were controlled in such a way that they postponed their charging processes at certain times in order to feed electricity back into the local distribution grid in a targeted manner. Result: In up to 60 % of cases, grid loads were successfully reduced. Flexible control proves to be a valuable lever, especially in times of high demand or high PV surplus.<\/p>\n

Intelligent forecasts with machine learning<\/strong><\/h3>\n

Intelligent forecasting models predict when and for how long a vehicle will be available - based on millions of real booking data from the car sharing system. In addition, the state of charge of the vehicle batteries was analyzed to find out how much energy can be stored or fed back into the system. On average, around 9 to 12 kWh of usable flexibility was available per vehicle - enough to buffer relevant grid loads with several vehicles in total or to store PV electricity temporarily in a meaningful way.<\/p>\n

Easy integration into the power grid possible<\/strong><\/h3>\n

The product model developed for marketing charging flexibility is a particularly practical success of the project: it can be easily integrated into existing systems of distribution grid operators, can be standardized throughout Switzerland and focuses on two applications:<\/p>\n
