Porsche demos grid balancing functionality of group of Taycan EVs with cloud-based pooling system

Porsche demos grid balancing functionality of group of Taycan EVs with cloud-based pooling system


A practical pilot take a look at performed by Porsche, the grid operator TransnetBW and consulting agency Clever Power System Providers (IE2S), has demonstrated {that electrical} balancing energy may be saved within the high-voltage batteries of an clever swarm of electrical vehicles. 5 series-production Taycan had been linked to the facility grid by way of the Porsche Residence Power Supervisor (HEM) each in a home atmosphere and below laboratory circumstances.

Consultants from Porsche Engineering had already tailored the software program of those management facilities beforehand for the sector take a look at.


The Porsche Residence Power Supervisor screens power and energy consumption. It protects the home connection from overload (“blackout safety”) and permits the usage of sensible charging capabilities.

The charging know-how of the Porsche Taycan and our Residence Power Supervisor and Cellular Charger merchandise have numerous potential for the long run: the pilot take a look at proved that. And the balancing energy market isn’t the one factor a pooling system of this sort can be utilized for. Superior options for inexperienced charging and different vehicle-to-grid functions are additionally conceivable. And that’s not all: if electrical automobiles feed electrical power again into the grid sooner or later for instance with a personal photovoltaic system, contributing to the growth of regenerative power, it can additional enhance the acceptance of e-mobility.

—Lutz Meschke, Deputy Chairman of the Government Board of Porsche AG

With the growth of renewable energies, balancing energy will grow to be much more necessary sooner or later for safe grid operation. The facility grid should at all times be steady, regardless that the wind and solar will not be at all times producing constant quantities of power. If energy grids will not be stabilized at a relentless energy frequency, there’s a danger of energy cuts. Till now, typical energy vegetation specifically have been accountable for cushioning these fluctuations. Utilizing high-voltage batteries as a buffer can be a win-win scenario: drivers of electrical vehicles may very well be financially compensated for his or her contribution to balancing energy.

The pooling system controls and coordinates the charging processes in actual time
The important thing factor of the info communication used within the pilot take a look at is a cloud-based pooling system developed by IE2S. This coordinates and controls the charging processes of the electrical automobiles in actual time, by translating the grid operator’s balancing energy setpoints into vehicle-specific alerts.

The pooling system additionally controls the high-frequency and synchronous bidirectional transmission of knowledge. With the intention to take a look at it, the pooling system was linked to TransnetBW’s primary management centre in Wendlingen close to Stuttgart.

The undertaking staff has managed to implement the advanced communication infrastructure between our management system and several other electrical automobiles. On the identical time, the strict specs for storing and supplying balancing energy have been met. It will allow us to combine electromobility into the clever energy grid of the long run.

—Dr Rainer Pflaum, CFO TransnetBW

For security causes, balancing energy is topic to strict requirements in Germany. Throughout the pilot take a look at, detailed measurements confirmed that the goal values from the grid management system had been met. This utilized to each the first (FCR: frequency containment reserve) and secondary (aFRR: computerized frequency restoration reserve) balancing energy. FCR is required to stabilize the grid rapidly, whereas aFRR has 5 minutes to grow to be absolutely obtainable.

The measurements had been carried out within the management system, within the property (the Taycan, Cellular Charger and HEM) and within the pooling system. For FCR, the HEM capabilities had been prolonged to incorporate native frequency measurement.

TransnetBW GmbH operates the electrical energy transmission grid in Baden-Württemberg. With this transmission community, the corporate secures the facility provide within the area, in Germany and in Europe. It manages and controls the power flows within the grid and is accountable for system stability in Baden-Württemberg. To this finish, it’s also researching future-oriented applied sciences and growing new processes.

Clever Power System Providers is a three way partnership between TransnetBW and MHP, the Porsche subsidiary for administration and IT consulting. Its mission is to make use of its mixed experience to advise corporations with enterprise fashions which can be being modified by the power and mobility transition.
