For Porsche, electric cars will be part of the network of the future | Digital Trends Spanish

Porsche envisions a future in which, when electric cars are not in motion, they feed energy back into the public grid. In this way, the fleet would act as a plant by supplying “balance energy”, which is what is known as the flow of electricity that levels out the dangerous fluctuations that can occur in the electrical supply system.

A pilot test carried out by Porsche with TransnetBW, the grid operator for the Baden-Württemberg region, and consultancy Intelligent Energy System Services, demonstrated that electrical balance energy can be stored in the high-voltage batteries of an intelligent swarm of cars and be used safely by the network.

The successfully completed test consisted of five production Porsche Taycan models connected to the power grid via the Porsche Home Energy Manager. The connection was made both in a domestic environment and under laboratory conditions.

The scenario envisioned by Porsche solves a major problem, as network security largely depends on stability achieved through a constant flow of power. But with the expansion of the use of renewable sources, such as solar and wind, the balance energy supplied by electric vehicles provides the necessary stability for the safe operation of electricity supply networks, since neither the wind nor the sun offer the constant energy needed for the required stability.

The use of high-voltage car batteries as balancing power sources could become a win-win situation for owners of these types of vehicles, who could receive financial compensation for their contribution.

Measurements taken during the test showed that the target values ​​of the network control system imposed by the strict regulations of the German government agencies were met.

The use of electric cars as balancing energy sources will make it possible to increase the use of renewable sources and will eventually cause electricity for electric mobility to flow in more than one direction.
