EV charging demand response pilot in Netherlands
September 19, 2018
German virtual power plant platform provider Next Kraftwerke has teamed up with electric vehicle smart charging platform provider Jedlix. The two companies will roll out a pilot to aggregate EV charging stations as a demand response utility through Next Kraftwerke's secondary control reserve on its virtual power platform.
The pilot has been commissioned by Netherlands transmission system operator Tennet in an effort to assess viability of new aggregated demand response and demand reserve technologies.
The pilot will begin next year, and is planned to run for two years. The pilot will be run in the Netherlands in TenneT's 150kV grid region within southern Netherlands. TenneT also operates as the high voltage grid operator throughout the Netherlands and in parts of Germany.
The aim of the pilot is to test the viability of offering customers cheaper EV charging by throttling demand within the network dynamically to offset power demands elsewhere in the grid. By throttling demand and load-balancing across the wider grid, utilities can avoid having to start up their reserve generators to produce more power, an expensive process that is initiated only to off-set peak demand.
The companies will combine Next Kraftwerke's Next Box and Jedlix's smart chargers to provide Next Kraftwerke with the demand data from the charging data. It will also analyse data across the wider grid to assess whether or not throttling is required, and to what degree.
Jedlix will develop new functionality within its customer apps, which will allow users to opt in to the programme, and specify to what degree they want to adapt their charging ratios.
Capacity from participating EV drivers will be aggregated into a higher capacity reserve which is added to Next Kraftwerke's virtual power plant platform.
At present, the pilot is demand response only. The companies are not combining it with vehicle to grid charging, although that has been mooted as providing additional resources for stressed networks.
"This pilot will bring essential innovation in the way electrical systems connected in private homes can contribute to Tennet's most demanding ancillary services," said Paul Kreutzkamp, Next Kraftwerke Belgium chief executive. "We are very happy to be starting this transition and bringing new sources of income to households together with Jedlix, which has set itself apart when it comes to smart charging of electric vehicles."
"We are thrilled to have this cooperation with Next Kraftwerke, which has the potential to establish the largest VPP for EVs in Europe and beyond," said Ruben Benders, Jedlix chief executive. "This cooperation, along with our deep technical integration with an ever-growing number of automotives and a smart charging solution via the connected car, ensures maximum value for the driver and allows every electric car to participate. Beyond that our cooperation leads to a reliable and valuable contribution of electric vehicles to grid stabilisation."
