H2020 Project:

• January 2016 – December 2019

• Total EU Funding ~ 12 M€

Smart Grid Context:

• TSO (Transmission System Operator) must balance national energy demand and production

• Relying on an energy market to satisfyneeds

• Involves bids submitted by aggregators(BSP: Balancing Service Providers)

• A power network backed by ICT enablesfiner Production / Consumption balancing

• Flexibility for balancing relies on• DG: Distributed Generation

• DR: Demand/Response adaptation mechanisms

• Grid decentralization is required• to mitigate risks

• to integrate distributed renewables

The FutureFlow Project

(aFRR = Automatic Frequency Restoration Reserves)

Initial architecture security assessment

Current security solution:

• Mostly relies on firewalls and VPN

• Basic access control implementations belowthe Oauth enabled Cloud platform

• Authorization managed independently at each stakeholder level:• Heavy to setup and manage• Risks of security breaches

Desired properties:

• Automatize security bootstrap of newlyconnected DR/DG

• Unify authorization management whileavoiding single point of failure

• Incerease flexibility via automatic tracking of contracts (DR/DG to BSP to TSO) and delivery

Use a Public Blockchain to automatizeenrolment and authorization of certified devices

1. Devices are manufactured and credentials are generated.

2. Buyer acquires device and provide installation information to the manufacturer (or current owner)

3. The device credentials are encrypted and published to the blockchain by the manufacturer.

4. Buyer retrieves the credentials from the blockchain

5. Buyer (or contracted aggregator) can use the credentials to take control of the device.

Several organizations are considering the use of blockchains to track devicecompliance and certification, as a way to build trust in IoT:• Zigbee Alliance• OCF• GlobalPlatform

Tracking of resource reservation and balancingcontracts via distributed digital ledgers

1. Agregated energy balancing bids, including DR/DG bookings, are exchanged and accepted through the communication chain, and capturedin the digital ledger

2. Aggregators archive DR/DG and/or balancing performance history in the ledger

Enhances market flexibility by dynamicallycapturing DR/DG contracts with fine dynamicity

Basis for a reputation system, where future bids take into account the past reliability of the DR/DG.
