DEMAND RESPONSE in the electricity market? 12 papers in open-access journal

If you are working with the green transition in the grid you should perhaps take a look at the open-access journal Energies by MDPI. In this Special Issue “Demand Response in Electricity Markets” you will find 12 peer-reviewed papers about the theme.

Professor Prof. Dr Henrik Madsen from (DTU Compute, Technical University of Denmark) and Dr Seyyed Ali Pourmousavi Kani (School of Electrical and Electronic Engineering, University of Adelaide, Australia) are guest editors at the journal.

How to predict the demand?

The future power system will host a significant amount of renewable generation inevitably. These energy resources are naturally undispatchable and unpredictable and do not necessarily follow the load demand. Therefore, safe and secure operation of the future power system will require extra flexibility in real-time operation to compensate for the varying generation. This will not be possible by large synchronous rotating machines, as they are slow, less economically efficient and polluting.

In this regard, Demand Response Programs (DRP) are attracting a lot of attention. Preliminary studies on Demand Response (DR) resources in integrated energy systems have already projected incredible potential to act as flexibility resources for power systems operations.

Nevertheless, there are still many questions and concerns related to DR resources involved in the electricity and energy markets, which have to be properly addressed.

This Special Issue publishes peer-reviewed papers from researchers from different discipline who offer solutions and algorithms to effectively incorporate DR resources in electricity and energy markets. These include the conventional day-ahead and real-time wholesale markets as well as P2P electricity trading considering stochasticity, unpredictability, and nonlinearity of the phenomenon. In this framework, physical and virtual energy storages and electric vehicles are also considered as DR resources. In our special issue, we have a special focus on how to model, forecast and control flexible resources in intelligent and integrated energy systems.

Keywords as:

  • demand response aggregation
  • electric vehicle
  • energy storages
  • market bidding mechanism
  • demand response in P2P trading
  • ancillary services
  • forecasting and control of flexibility
  • stochastic demand response
  • market operation with demand response
  • dynamic flexibility modelling and control
  • integrated energy systems
  • ICT solutions for demand response

We hope you will be inspired and learn new in the open-access journal Special Issue “Demand Response in Electricity Markets”. You are more than welcome to share with colleagues and your network.

March 26, 2020: Henrik Madsen is co-organizing a Virtual Workshop ‘Flexibility in Integrated Energy Systems’ at NTNU

How will a decarbonized energy system balance supply-demand operation to reach at least 60-70% of renewable energy sources (i.e., solar and wind) by 2050?

Flexibility will be at the centre to integrate renewables, support efficient system operations, and ensure security of supply. However, incentivizing and raising flexibility touches upon multiple technological and structural challenges (e.g. market and regulatory).

The workshop starts at 9:45am – ends at: 14:30pm.

The workshop with international speakers covers multiple aspects of ‘Flexibility in Integrated Energy Systems’. Three main sessions will be part of the workshop, which is as follows in the program:

  • Flexibility characterization, value, use cases and enablers
  • Energy systems integration, key flexibility technologies and industry perspective
  • Market design, regulation and barriers.

CITIES seminar in Edinburgh, January 2020

Edinburgh Research Group in Optimization – seminar with Henrik Madsen

On Monday, January 13, 2020, Professor Henrik Madsen visits Edinburgh Research Group in Optimization for a seminar talk: Accelerating the Green Transition Using Energy Systems Integration and Data-Intelligence

The energy system needs to undertake a fundamental change from a system where production follows demand to a system where the demand follows the production provided by fluctuating renewable energy sources. This talk describes methodologies for accelerating the green transition using AI, big data analytics, grey-box models, IoT, Edge and Cloud Computing.

First of all we shall focus on methods for characterizing and enabling the energy flexibility at the prosumer level, ie. at buildings, supermarkets, wastewater treatment plants, etc. 

Secondly we will describe a framework, called the Smart-Energy Operating-System, for using this flexibility for controlling the power load in integrated energy systems. 

Furthermore, this framework contains a set of methodologies which can be used for providing ancillary services (like frequency control, voltage control, and congestion management) for power networks with a large penetration of wind and solar power.

The set of methodologies is based on grey-box modeling, forecasting, optimization and control for integrated (power, gas, thermal) energy systems. We will demonstrate that by carefully selecting the cost function associated with the optimal controllers, the system can ensure energy, cost and emission efficiency.

Consequently, by using online-predicted values of the CO2 emission of the related power production, the framework provides an AI-based method to accelerate the transition to a fossil-free society.

Klimakonference i Sønderborg: Skræmmende udsigter, men konstruktive klimaløsninger

CITIES havde sit eget spor på konferencen ’100 % Climate Neutrality’ på Alsion i Sønderborg tidligere på ugen, samtidig med at der var et fælles spor med over 250 deltagere fra hele Europa. Her præsenterede internationale forskere alarmerende facts om klimakrisen og de medfølgende konsekvenser.

Alligevel kunne gæsterne gå hjem med en god følelse i maven, for konferencens viste også, at vi allerede har mange af løsningerne på de klimaudfordringer verden står overfor, skriver arrangørerne – herunder CITIES-partner ProjectZero – i en pressemeddelelse.

Nogle af Europas skarpeste klimahjerner var i ugens løb samlet i Sønderborg for at stille skarpt på den galoperende klimakrise. Og selvom der blev malet med den helt sorte pensel, da fakta og konsekvenser blev præsenteret, så kunne både gæster og deltagere ved konference går derfra med et grønt håb for fremtiden – forskere præsenterede nemlig en række løsninger, som kan forebygge konsekvenserne og bl.a. forbedre energieffektiviteten og ressourceanvendelsen.

”Et godt eksempel er det, som vi med en lidt teknisk term, som vi kalder ’energy payback-time’, som er den tid, der går, før elementet har produceret den energi, det krævede at fremstille det. For organiske solceller, som vi forsker i her på SDU Sønderborg, er den tid nu helt nede på 3-4 uger, lyder det fra én af initiativtagerne og arrangørerne af konferencen”, fortæller leder af Mads Clausen Instituttet Horst-Günter Rubahn.

De unge gjorde deres indtog på konferencen
Konferencen bød på indlæg fra ledende forskere og repræsentanter fra projekterne CITIES, ActNow, RollFlex, PE:Region, Energibyerne.dk og det ambitiøse ungeklimaråd fra byer i både Danmark, Letland og Tyskland.

”Jeg vil i den sammenhæng gerne fremhæve ungeklimarådet, som bragte vitalitet ind i konferencen som vi ikke tidligere har oplevet, og så er det jo i bund og grund dem det handler om. Det er deres fremtid”, vi kæmper for, siger Horst-Günter Rubahn.

De unge indtog scenen i forbindelse med konferencens afsluttende paneldiskussion, som understregede, at de ikke ønsker at pege fingre eller kaste skyld på tidligere generationer, men i stedet vil række en udstrakt hånd frem og opfordre til tæt samarbejde og en fælles front mod de klimaproblemer verden står over for.

Dermed var tonen en anden end da ikonet og den svenske klimaaktivist, Greta Thunberg, indtog talerstolen ved FN’s klimatopmøde i New York i sidste måned og beskyldte verdens topledere for at have stjålet hendes drømme og barndom. Men alvoren og engagementet var den samme.

Tager konklusioner med til København
Sønderborgs ProjectZero vision, har til formål at reducere Sønderborg-områdets CO2-udledning til et rundt nul allerede i 2029 og samtidig skabe nye kompetencer og grønne jobs i virksomhederne.

Også ProjectZeros direktør, Peter Rathje, er som medarrangør glad og stolt over klimakonferencen og dens konklusioner:

”Sønderborg og partnerne i bl.a. CITIES, Energibyerne.dk og ActNow-projekterne har været i gang i mange år. Konferencen bekræftede, at ambitiøse klimamålsætninger bedst løses i tæt samarbejde med lokale interessenter og at byer/kommuner er de nye klima-omdrejningspunkter når der skal sættes turbo på klimaindsatserne”, siger Peter Rathje, adm. direktør, ProjectZero.

Peter Rathje opfordrer Regeringen og ministrene til at styrke dialogen med byerne af de relaterede forskningsprojekter, hvor universiteter og virksomheder allerede samarbejder om de nye løsninger til verdens byer/kommuner.

Derfor vil Peter Rathje tage konferencens konklusioner med til bl.a. København, når 96 af verdens ledende byer i uge 41 mødes for, i endnu større skala, at sætte actions på verdens klimaproblemer i forbindelse med ‘C40 Mayors Summit’.

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.

The article is also in the newspaper Ingeniøren on Friday, August 16, 2019. If you are a member of IDA, you have access through your membership of the trade union. Otherwise, find the paper edition.

PhD defence, Friday 23 August 2019: COORDINATED PLANNING FOR RENEWABLE SMART ENERGY SYSTEMS

PhD defence: Louise Krog Jensen

THESIS: COORDINATED PLANNING FOR RENEWABLE SMART ENERGY SYSTEMS – HOW STRATEGIC ENERGY PLANNING COULD HELP MEET LOCAL AND NATIONAL GOALS

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.
