Professor: Think energy communities on a large scale

The electricity generation of the future gets a new player – the prosumer. For example, a homeowner with solar cells on the roof, who both consumes power and produces and sells his surplus power. GridTech and the Ingeniøren have taken a closer look at the energy landscape of the future – and talked with Professor, Henrik Madsen.

Local energy communities, where, for example, homeowners produce, share and trade in energy, will take over part of the energy production in Denmark. Electricity companies have a monopoly on transmitting power to the grid, but new EU rules now pave the way for energy communities. Several smart city projects at DTU including both CITIES and the Interreg-supported Smart Cities Accelerator work with energy communities.

This week, Teknologiens Mediehus’ pro-media GridTech and newspaper Ingeniøren are reviewing a report from Energinet Elsystemansvar og Dansk Energi, about the future of the electricity system, including the presumptions about how energy communities will characterize the electricity grid.

Among others, the centre leader of CITIES and the technical manager of the Smart Cities Accelerator, Professor Henrik Madsen, is quoted.

“Energy communities should be a larger area where multi-supply is shared – water, district heating, electricity and gas. If the energy community is just a few people trading electricity with each other, it does not give the same flexibility. It is also an expensive way to do it …,” he says to GridTech.

PhD defence: Louise Krog Jensen


Denmark is in the middle of a transition towards a 100% renewable energy system, and strategic energy planning was introduced by Danish politicians in 2012. Policy makers and officials have described strategic energy planning as a task for the Danish municipalities, but this has not been made a mandatory task with allocated funding. This has led to scattered energy planning in Denmark, wherein some municipalities have chosen to develop strategic energy plans while others have chosen not to.

This thesis investigates the coordination needs that emerge in the planning for a 100% renewable energy system and how local strategic energy planning can be developed to meet these coordination needs. The study was designed as a case study of a Danish Municipality to investigate in detail the different processes of local strategic energy planning.

To outline the context of the case study and to frame the concept of strategic energy planning applied in the analyses, a theoretical analytical framework for strategic energy planning in the Danish context has been developed to guide the analyses of local strategic energy planning.

The outcome of the study provide an insight into how local strategic energy planning is carried out in a Danish municipality today. Furthermore, are a list of barriers for successful strategic energy planning in connection to identified coordination needs identified, followed by suggestions for how to address and eliminate these barriers at the national and municipal levels.

VIDEO: Professor Henrik Madsen at CLEAN’s annual meeting

CITIES is a part of CLEAN – a cleantech cluster. CLEAN works as a facilitator of high-value cooperation between parties, by bringing members closer to markets, customers and peers. CLEAN does not close deals.

Last week Professor, research director and centre manager Henrik Madsen from CITIES and Smart Cities Accelerator participated at CLEAN’s annual meeting.

Here, a number of business leaders and researchers gave their bid on why partnerships are the way forward when we are to increase growth and innovation in Danish companies.

“For us at DTU, it is important that CLEAN facilitates the cooperation between us and small and large companies and end users,” says Henrik Madsen.

Press release: Focus on research resolves the problem with the electricity network capacity

CITIES’s partner in Center Danmark, EWII, published a press release yesterday, where their CEO, Lars Bonderup Bjørn, and project manager of CITIES, Henrik Madsen, commented on an analysis from Dansk Energi.

Today, an analysis was published by Dansk Energi, which concludes that the existing electricity network in Denmark does not have the capacity for the green transition that society is facing. It is, therefore, necessary to have an action plan from the politicians, which ensures that our electricity network is not overloaded – for example by the many electric cars we expect that will come on the road in the future.

At EWII, we support Danish Energy. Therefore, we have long been in the process of facilitating and initiating research in the area:

“We welcome this discussion. At EWII, we have chosen to invest money and employees in finding green solutions, because we completely agree with Dansk Energi that the electricity grid’s capacity is a problem we have to deal with,” Lars Bonderup Bjørn, CEO of EWII, says.

“We have, among other things, a green research centre, Center Danmark, which facilitates research into solutions in that area, and we have a number of projects that focus on precisely the challenge of the electricity grid capacity,” he says.

These include Flexible Energy Denmark (FED), which is a research project supported by the Innovation Fund Denmark. The project aims to develop green solutions using data and artificial intelligence, and in this way seek to utilize the green energy in the best possible way, so that no peak loads occur on the electricity grid in the “rush hour”, where everyone wants to cook, wash clothes and charge their electric car at the same time.

“It is absolutely necessary to prioritize research that supports the green transition while ensuring that our infrastructure is able to cope with the changes,” Lars Bonderup Bjørn says. He is also chair of the steering committee in Flexible Energy Denmark.

Professor at DTU Compute, Henrik Madsen, Head of Center for IT-Intelligent Energy Systems in Cities (CITIES), is one of the researchers participating in Flexible Energy Denmark:

“With the FED project, we get the opportunity to research a better use of green energy. So far, the electrical systems have mainly been designed so that production follows consumption. But in the future, where solar and wind energy will be dominant, there will be a need for electrical systems that are designed in such a way that consumption in the future must follow the production,” he says.

“The FED project will contribute to a reduction in the climate impact, better finances, and greater security of supply in the electricity grid. The project will lead to a more efficient energy system, where investments in electricity networks, wind turbines, solar energy production, etc. will be better utilized. The key to it is to utilize the great flexibility potential of the multi-supply systems through new digitization solutions – for example by storing the energy surplus from the wind turbines in district heating systems,” Henrik Madsen says.

There are 24 partners in the project, and they include universities, companies and stakeholders in the supply industry. EWII, together with DTU, is in charge of the project, which started on April 1, 2019.

Documents from: CITIES workshop in Zagreb – Data intelligent operation of DHC – April 3rd-4th 2019

At a two-day workshop in Zagreb first in April different industry, academia and governmental partners focused on the importance of data-intelligent operation of integrated power and thermal systems for accelerating the green transition using thermal storage solutions on the proper scales.

Center for IT-Intelligent Energy Systems (CITIES) project at DTU in Denmark was responsible for the workshop.

See the documents from the workshop below for details.


In recent years, there has been a growing interest in using big data to improve district heating and district cooling systems. Sensors are becoming cheaper, and the use of smart meters, which measure hourly heat consumption at every consumer, in the district heating systems became more common. The vast amount of data can be used for constructing better models, resulting in lower operating costs of district heating and district cooling systems. Moreover, cogeneration units, large heat pumps and electric boilers in district energy systems have to bid for electricity on day-ahead markets. The result of this changing framework for district heating and district cooling operation is increased complexity of operating the systems but also an opportunity for economic, CO2 emissions and energy savings in the system.

Furthermore, efficient and successful integration of large-scale variable energy sources like wind and solar energy calls for a rethinking of the design and operation of energy systems and their interaction with other sectors of modern society. Current energy systems where supply is following the demand will change to a system where the demand must follow generation. Consequently, this calls for a switch of focus towards unlocking and describing the energy flexibility at all levels of the energy system. Here, the thermal inertia of district heating/cooling systems will play an important role, as the scale of the system is essential for providing the needed solutions; e.g. solutions for seasonal storage.

Center Denmark appoints new director

Center Denmark, Denmark’s new digitization hub for smart energy systems and green transition, has named the new director from June 1, 2019 – Søren Bording. The 39-year-old future director comes from a position as Loads & Control director i Vestas. Therefore he has a good overview of the green community, which the new center should strengthen.

Read more about the new director and Center Denmark in the Danish press release below.

And read more about the first project – Flexible Energy Denmark (FED) in Center Denmark – a new 44 mill dkr project, funded primarily by Innovation Fund Denmark, and proactive players in the Danish electricity sector here.

Det bliver den 39-årige Søren Skov Bording, der sætter sig i chefstolen for Danmarks nationale forskningscenter for grøn omstilling, Center Danmark. Søren Bording kommer fra en stilling som Loads & Control director i Vestas og har derfor et godt blik for det overordnede grønne fællesskab, som det nye center skal styrke:

”Det bliver ekstremt spændende at starte samarbejde med de forskellige partnere i Center Danmark. Sam men skal vi koble ny forskning og teknologi med innovative forretningsmodeller og løsninger i energinettet,” siger den nyslåede direktør.

Centret, der endnu ikke har en fysisk ramme, er et samarbejde mellem EWII, Energinet, Thorsen Invest, samt de fire universiteter Danmarks Tekniske Universitet (DTU), Aalborg Universitet, Syddansk Universitet og Aarhus Universitet. Det kommer til at fungere som samlingssted for viden,
der kan fremme Danmarks grønne omstilling. Målsætningen er at opbygge et ”energiens Silicon Valley”:

”Med Center Danmark udbygger vi Danmarks position som foregangsland på den grønne omstilling. Jeg forventer, at vi i Center Danmark vil udvikle en banebrydende digital platform, og blive et hotspot internationalt for nye intelligente løsninger,” siger Søren Bording.

Formand for Center Danmark Fonden og administrerende direktør hos EWII, Lars Bonderup Bjørn, glæder sig over, at det er lykkes at finde den helt rette mand til jobbet:

”Det er vigtigt, at direktøren for Center Danmark har kendskab til energisystemer, solid erfaring med grøn energi samt en god forståelse af IT som samfundsmæssig infrastruktur. Det er de kriterier, vi har lagt vægt på ved ansættelsen, og som vi nu har fået indfriet. Vi er meget glade,” siger Lars Bonderup Bjørn.

For nyligt valgte Innovationsfonden at tildele Center Danmark 30 millioner kroner øremærket til det fire-årige forskningsprojekt ”Flexible Energy Denmark” – FED. Projektet fokuserer på at udvikle løsninger til omstilling af vores nuværende forsyning til en fremtidig grøn energiforsyning – for eksempel ved at fokusere på bedre udnyttelse af digitale data i elforbruget. Projektet bliver en af de første, større opgaver som centret skal varetage.

Søren Skov Bording tiltræder som direktør for Center Danmark d. 1. juni 2019.
