How the VPP – Power Hub - works Examples of assets in the Power Hub portfolio
Gasturbine at Novo Nordisk
Asset
5 MW gasturbine
Primary purpose
Process steam
Secondary use:
Generation and ancillary services
Diesel genset at Skærbækværket
Asset
2 MW diesel generator
Primary purpose
System backup
Secondary use in Power Hub:
Generation and ancillary services

How the VPP – Power Hub - works Delivering primary regulation through remote control of hydro power plant
7
Harteværket (hydro power plant)
was one of the first 3rd party
participants in the Power Hub
project.
When Vester Nebel Å was put back
in its old riverbed in 2008 the plant
lost approx. 80% of its water and
was threathened by closure.
By delivering ancillary services
Harteværket has been able to
compensate financially the effect of
the large reduction in water flow
Delivering ancillary services would
have been very difficult for the plant
without Power Hub.

Background
Electrical isolated
Often blackouts
Expects more windpower
Faroe island LUs:
2 heatpumps (salmon farming)
1 coldstore
2 heatpumps (freezing)
Faroe island grid controlled:
2 radials in the Faroe power grid
Purpose
Increase system stability using VPP

Complexity rules in the real world Building the operational platform and business proces integration is not trivial
Varying DER regulation capabilities and control technology impacts mobilisation
DER owners awareness of capabilities and potential Flexibility, ancillary services and reserves markets are not commonly known topics
Linking flexibility to business processes rather than technology is paramount
Standardisation and Smart Grid enabling Necessary modifications to DER control technology often ruins the business case
Of the shelf Smart Grid enabled/compliant units could accellerate smart grid roll out
Market reforms and regulatory changes Restructuring markets in terms of bid size, duration and gate closure
TSO approval of a VPP as a single unit instead of approval of every unit in portfolio
Learning Points Mobilising distributed energy ressources (DER)

Vision of a Smart City Integration and orchestration of all energy resources and infrastructures

The cont. development of renewable energy (RES) will have a strong impact: Displacing conventional generation – with no incentives to invest in new
In current regimes and markets – RES are not participating in balancing
New solutions are required to compensate for the effects of RES: Mobilisation of distributed generation – when RES cannot cover demand
Mobilisation of demand side flexibility – when there is an excess generation
Both sides must provide balancing services at TSO and DSO level
One key to succes is creating incentives for local assets to participate: Controlling local units technically is (next to) trivial
Creating value under the current regimes is challenging
DONG Energys VPP – Power Hub – is doing both! Pooling capabilities of local assets to help compensating for the effects of RES
Clustering, e.g. landbased wind, on market conditions as part of the portfolio
Creating value for owners through integration to energy markets and reserves markets
