Professor Henrik Madsen awarded best Senior Presenter

Earlier this week, Professor and Centre Leader at DTU Compute Henrik Madsen was awarded with the prize for the best Senior Presentation at the 5th International Conference on Smart Energy Systems in Copenhagen.

The presentation ’Perspective in Using Meter Data for Temperature Optimization’ was based on knowledge from the project CITIES, Smart Cities Accelerator, IDASC (Intelligent data-anvendelse i Smart Cities), Heat 4.0, and FED.

The presentation was so exciting and well communicated that Henrik Madsen won the prize of 1000 Euro sponsored by Kamstrup.

The nomination was justified by ”his (Henrik Madsens, red.) enthusiasm is still fully alive after all the years of experience. He keeps pushing the boundaries of control methods.”

Professor Henrik Madsen was very pleased and surprised by the award for his presentation.

The point of the theme in the presentation is that ‘data is gold’.

“With new meters and frequent meter readings we are finally at a stage where we can benefit from a next generation of tools for forecasting and control based on data-analytics and machine learning,” he says.

“We have demonstrated that this gives new possibilities for smart control of low temperature district heating. This new generation of district heating systems will pave for an acceleration of the green transitions with more efficient supply, better use of heat pumps and excess heat, and for unlocking the flexibility in DH systems needed for the fossil free energy system,” Henrik Madsen says.

Kamstrup is a world-leading supplier of intelligent energy and water metering solutions, so Henrik Madsen’s presentation resonated with the companys interest.

“Henrik’s presentation was an excellent example on the potential for increased digitalization in the DH industry. Temperature optimization based on real time data from smart meters makes it possible to operate the network closer to the limits and is thus a key enabler to lower the temperature levels in a DH system. And lower temperatures is a necessity for integrating large amounts of waste heat and renewable energy in the system,” says Steen Schelle Jensen, Head of Product Management – Solutions in Heat/Cooling Division at Kamstrup.

Hong Kong: CITIES model for Energy Systems in Smart Homes

Hong Kong: CITIES model for Energy Systems in Smart Homes

These weeks, Hong Kong is massive in the media due to major demonstrations and unrest in the city, but life in the city continues alongside. Last week, PhD student Hjørdis Amanda Schlüter and Professor John Bagterp, both affiliated with CITIES and the Smart Cities Accelerator at DTU Compute, attended the IEEE CCTA 2019 (Conference on Control Technology and Applications) in Hong Kong.

Here, on August 20, 2019 Hjørdis Amanda Schlüter presented a new model, EMPC, to manage the energy system in smart homes (Economic Model Predictive Control for Energy Systems in Smart Homes).

Here, the energy system basically consists of a stationary battery, photovoltaic solar cells on the roof, a heat pump for heating and an electric car where the battery has to be charged.

Using weather forecasts, thermal comfort and driving profiles, EMPC coordinates this energy system and its interaction with the external energy system by buying and selling electricity at prices announced in advance.

DTU Compute is not the first to present such a model. It has been done before, for example, by Stephen Boyd (Department of Electrical Engineering, Stanford University) in the article “Dynamic energy management with scenario-based robust MPC”. There he and his people focus on the software they have created to control a smart home energy system. ‘

“Our focus is on developing the simplest model we could think of. The model is so simple that it is easy to set up for others who do not know so much about the subject,” says Hjørdis Amanda Schlüter.

The conference was quite small and some of the participants did not show up due to the unrest in Hong Kong. Nevertheless, about 20 researchers and firms found their way to Hjørdis Amanda Schlüter’s presentation, and she got a lot of questions about the model.

The research continues with two graduate students who will be writing a thesis at John Bagterp this semester. They have to reproduce Hjørdis Amanda Schlüter’s results and then extend the model to a whole street instead of a single house.

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.

CITIES article in the magazine Dansk Fjernvarme

The article is in Danish.

Fjernvarmen spiller en afgørende rolle i fremtidens smarte el-system i Danmark, viser erfaringerne fra CITIES-projektet.

I ’Dansk Fjernvarme’ fortæller professor og centerleder på CITIES Henrik Madsen, at intelligent brug af varmepumper i fjernvarmesystemerne kan levere den fleksibilitet, der er nødvendig for integration af store mængder vind- og solenergi.

Dermed vil fjernvarmen kunne spille en nøglerolle i en økonomisk effektiv omstilling mod et fossilfrit el-system. Forudsætningen er dog, at der indføres dynamiske energiafgifter, som baseres på, hvor grøn strømmen er.

Business desk article about SmartNet in holiday homes

Last week Smart Cities Accelerator with center leader for CITIES Henrik Madsen participated at the Danish Folkemødet. Henrik Madsen talked about the new research from the SmartNet project where it has been possible to create coherence between the surplus production of wind energy especially at night and the local electricity consumption in 30 holiday homes with indoor pools in Blokhus and Blåvand at Vestkysten.

The perspective is enormous, and therefore the partners continue under the project Center Denmark.

The Danish media Nordjyske Medier has published an article about the research and also talked with an owner of a holiday home. Read the article here

Looking forward: Workshop on Joint NTNU-DTU Proposals for European & Nordic Research Programmes

Looking forward: Workshop on Joint NTNU-DTU Proposals for European & Nordic Research Programmes

Monday, June 3rd DTU’s project CITIES and our Norwegian colleges from NTNU and SINTEF (project FME ZEN) are having a closed workshop at DTU Lyngby Campus, Copenhagen. The aim is to make a coordinated effort in applications, we expect to increase the likelihood of funding.

The two large national projects – CITIES and FME ZEN – have similar synergies. Together we want to unlock, describe and test flexibility at all levels from buildings, districts to cities, by empowering integrated energy systems using digitalization and artificial intelligence.

Around thirty experts from NTNU, SINTEF and DTU participate.

Flexible Energy Denmark – establishing a digital infrastructure for the near 100 pct fossil-free society

Flexible Energy Denmark – establishing a digital infrastructure for the near 100 pct fossil-free society

DTU Compute

Flexible Energy Denmark (FED) is a new 44 mill dkr project, funded primarily by Innovation Fund Denmark, and proactive players in the Danish electricity sector.

According to the scientific project leader, Professor Henrik Madsen (DTU Compute), aims at establishing a national digital infrastructure for the near 100 pct fossil-free society:

This infrastructure is built on leading expertise related to data lakes, advanced statistics, AI, big data analytics, cloud/fog/edge computing and IoT technologies. In the FED project the solutions will be demonstrated at seven living labs at different locations in Denmark.

The solutions will provide the digital backbone and data-intelligence sphere of Center Denmark, which is a new national digitalization hub for smart energy systems with a coupling to the food and water sectors. Center Denmark is lead by eg. Energinet.dk, EWII, and all technical universities in Denmark, ie. DTU, AAU, AU and SDU. The solutions are built on important initiatives like the IEA ECB Annex 67, lead by Danish Technological Institute, as well as leading smart energy research projects like CITIES (Center for IT-Intelligent Energy Systems) and DiCyPS (Center for Data-Intensive Cyber-Physical Systems)

The transition to a low-carbon society based on intermittent renewable energy sources calls for a change to an energy system where the demand follows the production. This requires a development of new methods to enable flexibility at all levels of the energy system of the modern society. At the same time the system is evolving from a centralized system into a complex set of integrated systems at scales that includes customers, cities and regions. Due to the complexity, the real time matching of energy demand with production has to take place through data analytics and IoT devices in integrated energy systems.

The objective of FLEXIBLE ENERGY DENMARK (FED) is to unlock, describe and test energy flexibility at all levels, by empowering integrated energy systems using digitalizations and data intelligence. We establish a new nationwide data platform of connected Living Labs (Uni-Lab.dk – upcoming) facilitating the coupling of existing domain specific labs and enabling new synergies. FED will provide data intelligent tools and solutions for Center Denmark (CD) which will host Uni-Lab.dk. The FED digitalization addresses all steps of the value chain from sensors to analysis to decision support.

FED creates innovative solutions based on Uni-Lab.dk data, state-of-the-art tools and existing and new products from leading industry partners. FED provides data, AI and IT methodologies enabling the industry to be highly competitive in the digitalization of the energy systems. Hence, FED provides the foundation for a national leadership on green innovation.

FED supports the industrial partners to advance their PRODUCTS to the next generation of data-intelligent solutions and test them in a representative environment of Living Labs (Uni-Lab.dk). Thereby, drastically reducing the time-to-market for the new solutions (Fig. 1). FED creates new knowledge about energy flexibility to be used for both green innovations (product level) and the green transition (policy level).

Our tools are data-driven exploiting data from several energy systems. Heterogeneous data from 7 Danish Living Labs and industrial partners are collected into an integrated open data lake. The lab-activities in FED provide the foundation for a Danish chapter of the international, smart energy UNILAB (named Uni-Lab.dk) combining proof-of-concept and demonstration with a unique possibility to scale up the algorithms and develop them to fit the needs of the Danish and the International society.

Furthermore, this Digitalisation of heterogeneous data into the data lake allows the implementation of fast and standardised evaluation procedures. The process continues as an iterative cycles: Based on measurement in Uni-Lab.dk and on the impact of our solutions, we feed the data lake with new data and further develop improve tools, products (indirectly) and solutions which again are tested under real life conditions in Uni-Lab.dk.

Demoprojekt fra CITIES nævnt på Energy-Supply.dk

Demoprojekt fra CITIES nævnt på Energy-Supply.dk

Demonstrationsprojektet ‘Operational planning and bidding for district heating systems’ blev i går beskrevet i en artikel på Energy-Supply.dk

Demonstrationsprojektet i Hvide Sande har til formål at øge lagringsevnen og fleksibiliteten i det danske energisystem ved at lave avancerede computermodeller, der baseret på maskinlæring laver simulationer af alle de forskellige aspekter af energimarkedet og vejrforhold. Det intelligente styreværktøj kan derefter bruges til at forudse, hvordan forskellige typer vejr påvirker energimarkedet og dermed elpriserne.

Fjernvarme kan skabes ved hjælp af mange typer energikilder og teknologier, og man kan spare og tjene mange penge ved at bruge den rigtige teknologi på det rette tidspunkt.
Illustration: DTU Compute

– Vi bruger et to-trins stokastisk program med scenarier for usikkerhederne som elpriserne og produktionen af vedvarende energi. Det kan fortælle operatørerne, hvordan de skal reagere, hvis vind- og vejrforholdene forandres og/eller markedspriserne ændres, siger en af projektdeltagerne, postdoc Daniela Guericke og tilføjer:

– Det gør det nu muligt for fjernvarme leverandører at optimere deres fleksibilitet og reducere omkostningerne.

Den øgede fleksibilitet giver økonomiske fordele, da valg af den rigtige varmeteknologi på det rigtige tidspunkt kan spare eller endda tjene fjernvarmeproducenten og kunderne masser af penge. Hvis elpriserne er høje, kan kombinerede kraftvarmesystemer opvarme vandet og opbevare det til senere, mens der produceres elektricitet til videresalg. Er elpriserne lave på grund af overflod af vind, opvarmes vandet ved hjælp af el.

Ulempen er, at vedvarende energikilder er svære at forudsige, og her vil det nye intelligente beslutningsværktøj være en uvurderlig hjælp.
