EU transmission system operator Tennet partnered with a utility and energy solution providers to deploy smart grid pilots in Germany and the Netherlands.Tennet is partnering with energy storage solutions provider Sonnen to deploy the project and improve Germany's grid system whilst in the Netherlands, the TSO is collaborating with renewable energy utility firm Vandebron.

In a combined statement, Tennet said it is collaborating to demonstrate how technology can be used to help grid operators manage distributed energy resources (DERs) to sustain the reliability of grid networks.

Under the pilots, IBM will develop a ‘blockchain network’ which will be used to verify and communicate the performance of decentralised energy resources to enable real-time management of DERs and grid network in line with energy demands.

[quote] The blockchain network will use hyperledger fabric to integrate energy stored in electric cars and household batteries into the electrical grid, says the statement.

Mel Kroon, CEO of Tennet, said the pilots are part of the company's Digital Transformation Programme and will be used to improve renewable energy integration and consumer flexibility in the two countries.

In German, Tennet and Sonnen will use the blockchain system to transport energy generated from wind in north Germany to South Germany, store it in residential solar battery energy storage systems and provide it into the grid to meet demand.

V2Gs and grid system reliability

In the Netherlands, Vandebron will recruit its customers with V2Gs to participate in the project.

Participating customers will be able to integrate energy stored in their V2G batteries into Tennet's grid system to help the TSO stabilise the country’s high voltage grid in the event of imbalance between supply and demand.

Tennet's 22,500km of high-voltage energy network provides energy to some 41 million consumers in Germany and the Netherlands.

Meanwhile, Enel Energia, Nissan Italy and the Italian Institute of Technology (IIT) are reportedly launching the first corporate electric car sharing pilot with V2G charging.

The system created under the pilot will allow electric cars to discharge power to the network and contribute to its stability. According to Nissan's website, the first "vehicle to grid" (V2G) electric car recharging facilities have arrived in Italy.

Nissan says that "V2G technology allows e-cars to be considered as real 'batteries on wheels', able to store unused power and discharge it to the grid. All these functions are available thanks to bi-directional charge management." Read more...
