Renewables challenge the GridRenewables fundamentally change how power grids work

The old Electrical

Power System

The new Electrical

Power System

Big fossil or nuclear power plants

close to the industrial centers feed

electricity into the transmission grid.

The connected distribution grid

supplies consumers.

Renewable energy, produced locally,

sometimes far away from industrial

centers and storage facilities provide

electricity at all grid levels depending on

the weather.

Distributed FlexibilityWith an increasing amount of volatile renewable energy in the system, an

optimal dispatch of flexibility options is needed to guarantee security of

supply and affordability.

Flexible supply

Innovation drives the Energy

System of the FutureDecarbonisation and the resulting decentralization of power supply raise demand for

digital innovations.

New Solutions for New demands • Use windfarms for Voltage control

• Public EV Loading stations are used for Frequency

containment reserve

• Shorter timeframes (Month or week) for services towards

TSO, create auction platforms

• International Grid Control Cooperation (IGCC) for

regional ACE exchange

• Soft coupling of Synchrounous Areas supports frequency

and reduces frequency oscilations (BritNed trial)

• Short and Medium Term Adequacy (SMTA)

• DC Overlay grid/corridors

• Stricter Under Frequency Load shedding

• Coordinated Balancing Areas (COBA’s)

EV cloud

• Connect small suppliers of balancing power

• Use blockchain for efficient communication and contracts

• Scalable towards full IoT potential


BalancingBalance between production & demand

production = demand : = 50Hz

production > demand : > 50Hz

production < demand : < 50Hz

Automatic demand reduction

Maintaining the balance

Frequency ↓ reserves “ramp up”, or provide power;

Frequency ↑ reserves “ramp down”, or consume power.

TenneT NL is obliged to contract:

• 107 MW for FCR – weekly tender (www.regelleistung.net);

• 348 MW for aFRR – quarterly/yearly contracts.

Unlocking Flexibility by Using Blockchain

Blockchain technology offers opportunities for efficient

market integration of distributed flexibility providers

• smart blockchain technology

facilitates market access for

flexibility services to prosumers,

creating a customer-empowered

energy system

• the technology therefore

potentially increases energy

supply and thus can help

stabilize grid costs

• blockchain potentially provides a

transparent, easy to access, and

safe platform for trading system

services


What is a Blockchain?

2/5/2018

Transactions without blockchain Transactions with blockchain

• A blockchain is a distributed and shared database that facilitates transactions

• Transactions are aggregated in blocks that are validated and added to the so called

blockchain

• The blockchain is a growing chain of blocks of transactions, documenting transaction

history and validating transactions

• Blockchain technology in connection with smart contracts allows for a high degree of

automatization and security, drastically reducing transaction costs


Public vs. Private Blockchain?

2/5/2018

Public BlockchainPrivate Blockchain

• Anonymous and free access

• Users trade directly with all other users

• Resource-intensive validation procedure in a

peer-to-peer network

• Low flexibility for development of blockchain

functionalities

• Comparatively high total operating costs and

energy consumption

• Decentral control approach

• No ex-post revision possible

Examples: Bitcoin, Ethereum

• Permissioned access: participants are known

and qualified to participate

• Easier and faster validation process: verification

performed by operators

• Access to data limited to those who need to

know

• Highly flexible: transactions comply with the

rules the operator sets

• Comparatively low operating cost and energy

consumption

• Possibility for Intervention by the operator

• Most favorable for business applications

Examples: Nasdaq LINQ, Barclays Corda


Revolutionizing the Energy System

The new energy system with blockchain

Central

power

Power

Suppliers

• By reducing transaction time and

costs, blockchain technology has the

potential to empower prosumers

• Blockchain lowers transaction costs

and barriers for active participation in

an energy system that increasingly

relies on decentralised assets and

actors.

• Blockchain facilitates safe transactions

directly between suppliers and

consumers

• Intermediaries, like power suppliers,

will play a smaller role in facilitating a

functioning energy market

• In a system with a progressively

smaller fraction of large scale

centralized assets, blockchain unlocks

liquidity in the balancing and energy

markets

• Combining smart contracts with the

blockchain allows for automated

balancing of supply and demand


• Large scale production will be

less and less available for

system services

• Distributed flexibility sources

must be tapped to keep the grid

stable

• Blockchain can make a large

number of small scale flexibility

sources available for system

services.

• Through the blockchain, home-

production and storage facilities

as well as EVs can act as

virtual power plants

System Services via Blockchain


TenneT and Blockchain Technology

In two pilot projects with Sonnen and Vandebron, TenneT

is using a private blockchain to balance the grid.

• Objective: gaining practical experience with blockchain

technology and interfacing with existing TenneT systems

and processes.

• Building on existing blockchain implementation:

Hyperledger is an open source collaborative effort

created to advance cross-industry blockchain

technologies.

• Two parallel applications:

• Netherlands: Vandebron provides automated

secondary control reserve from a pool of charging

stations for electric vehicles (aFRR-application)

• Germany: Sonnen pools household batteries to

provide redispatch/congestion management

services

• The flexibility is managed by TenneT via an IBM

blockchain solution and used to balance the grid

• Platform-based services intended to become accessible

for all market participants once the pilot runs successfully

• High potential for distributed flexibility: The potential of

battery storage for Germany alone lies between 15-60

GW by 2030

TenneT is Europe’s first cross-border grid operator for electricity. With about 21,000

kilometres of (extra) high-voltage lines and 36 million end-users in the Netherlands and

Germany, we rank among the top five grid operators in Europe. Our focus is to develop a

North-west European energy market and to integrate renewable energy.
