Porsche recently tested vehicle-to-grid (V2G) capability using five Taycan models interlinked using the Porsche Home Energy Manager (HEM) and connected to a grid from operator TransnetBW. Consulting firm Intelligent Energy Systems Services (IE2S) also took part in the experiment.
Balancing power supplied from an external source back into the grid helps balance out fluctuations in the power grid. As more and more vehicles rely on electric power in the future, balancing power will become very important to preserve the stability of the grid and prevent power shortages. Power grids need to be stabilized at a constant 50 Hertz power frequency to avoid disruptions in service. Up until now, power grids have used balancing power supplied by conventional power plants to even out fluctuations in the power frequency.
“The charging technology of the Porsche Taycan and our Home Energy Manager and Mobile Charger products have a lot of potential for the future: the pilot test proved that. And the balancing power market isn’t the only thing a pooling system of this kind can be used for,” says Lutz Meschke, Deputy Chairman of the Executive Board of Porsche AG. “Advanced solutions for green charging and other vehicle-to-grid applications are also conceivable. And that’s not all: if electric vehicles feed electrical energy back into the grid in the future for example with a private photovoltaic system, contributing to the expansion of regenerative energy, it will further increase the acceptance of e-mobility.”
In the future, it may become necessary to source balancing power from other participants, namely the electric vehicles connected to the grid. As you can imagine, this requires complex calculations and multiple variables must be taken into account.
“A real measurable milestone: the project team has managed to implement the complex communication infrastructure between our control system and several electric vehicles. At the same time, the strict specifications for storing and supplying balancing power have been met. This will enable us to integrate electromobility into the intelligent power grid of the future,” explains Dr Rainer Pflaum, CFO TransnetBW.
