Session: Demand Flexibilty - Dream or Reality

Im Rahmen des IEA DSM Task 17 organisierten die beiden Operating Agents Matthias Stifter und Prof. René Kamphuis (TU Eindhoven, TNO) Vorträge und eine Podiumsdiskussion zum Thema Demand Response. Es nahmen mehr als 100 Interessenten teil. Unter dem Titel „Verbraucherflexibilität – Traum oder Realität“ präsentierten Teilnehmer aus aller Welt ihre realisierten Projekte. Im ersten Teil wurden theoretische Grundlagen und Simulationen vorgestellt und im zweiten Teil Ergebnisse aus Demonstratoren und living labs.

Höhepunkte waren unter anderem die Vorstellung der „Roadmap to Flexibility“ (Roman Targosz, Copper Alliance Europe), Anforderungen des Energiemarktes und elektrischen Netzes an die Integration von Flexibilitätsdienstleistungen in der Schweiz (Matthias Galus, BFE) und Österreich (Tara Esterl, AIT). Die Perspektive des Netzbetreibers präsentierten zwei Holländische Betreiber (Arnoud Rijneveld, STEDIN und Marijn Renting, ENEXIS) welche um die Empfehlungen aus dem europäischen regulatorischen Umfeld ergänzt wurden (Werner Friedl, AIT). Die Anforderungen an die Interoperabilität und  Einbindung von Gebäuden (Steve Widergren PNNL) und Werkzeuge für die Validierung von Flexibilität (Stephen Galsworthy) wurden vorgestellt. Zuletzt wurden Ergebnisse aus dem EcoGrid EU Projekt (Matthias Stifter, Florian Judex, Fabian Leimgruber, AIT), Smartgrid Gotland (Daniel Brodén, KTH) und PowerMatchingCity-II (Elke Klaassen, Enexis) präsentiert.

Verbrauchsflexibilisierung (Demand response)

Demand Response als eine Maßnahme, um die Flexibilität im Energiesystem zu erhöhen, ist bereits realisiert, zum Teil politisch und regulatorisch eingefordert und von der Industrie breit unterstützt. Aktuelle Entwicklungen aus Forschungsprojekten und Demonstratoren ebnen den Weg für großflächigen breitenwirksamen Einsatz und Kommerzialisierung. Diese Veranstaltung präsentierte verschiedene internationale Ansätze und diskutiert den aktuellen Fortschritt der Einführung in Markt und Netzbetrieb und die Herausforderungen an regulierungskonforme Einführung.

Diese Veranstaltung wurde organisiert und unterstützt von IEA DSM Task 17: Integration of Demand Side Management, Distributed Generation, Renewable Energy Sources and Energy Storages. Task 17 adressiert die Rolle und Potentiale von Flexibilität von Verbrauch (z.B.: Elektroauto, Wärmepumpe) und Erzeuger (Photovoltaik) im Endkundensegment und der Auswirkung auf Netze und Märkte.

  Introduction to IEA DSM Task 17 phase 3

• 9:45 Theoretical foundations and simulations

• 9:45 Mapping flexibility of power systems
  Roman Targosz (Copper Alliance Europe)

  Copper alliance and Ecofys have been involved in a joint study on flexibility in power systems. A new overview clarifies the flexibility needs for the transition to power systems with very high penetration levels of variable renewable energy sources (VRES). The talk provides a comprehensive assessment of the complete spectrum of flexibility options and identifies key barriers for their deployment.

• 10:00 DSM in Switzerland – Possible Coordination of Networks and Markets
  Matthias Gallus (Swiss Federal Office of Energy SFOE)

  The coordination of flexibility (load,Production, storage) for markets and networks at the same time is a complex task. Switzerland is looking into solutions, which offer large playing field for markets and competition. Of interest are topics such as benefits for markets, networks and total social welfare, dynamic innovation, data exchange, processes for markets and non-discriminatory access.

• 10:15 Load flexibility in small and medium enterprises and criteria for successfully enabling them
  Tara Esterl (AIT Austrian Institute of Technology)

  In the project hybrid-VPP4DSO DR-components in Austria and Slovenia are studied regarding their flexibility potential and their willingness to provide their flexibility. Potential business models and business cases are investigated to make use of this flexibility in different markets. Furthermore, the impact on the grids is analyzed and how this flexibility can relieve the grids in critical situations. Hybrid solutions - serving both markets and grids - are challenging regarding unbundling requirements, but have the highest priority of the project.

• 10:30 Valuing Flexibility in power systems: the ValueFlex project
  Stephen Galsworthy (TNO Netherlands Organisation for Applied Scientific Research)

  The VALUEFLEX project aims at developing services able to give to utilities and grid operators a better understanding of the value of electricity flexibility. These services are based on a comprehensive set of simulation tooling (the Toolbox) that allows companies to analyse the economic and technical feasibility of demand response services.

• 10:45 Buildings Equipment Connectivity Interoperability for Energy Applications
  Steve Widergren (PNNL, USA)

  Buildings automation can become a major contributor for providing flexibility services to the electric grid and greater overall energy efficiency, but the vast majority of facilities (at least in the USA) are not prepared to easily coordinate with the grid even if an flexibility signal was available.  Efforts are underway to advance interoperability of connected building equipment to bring down integration costs and enable buildings to be more efficient and flexible users of energy.

• 11:00 Coffee break

• 11:15 Realized demand response

• 11:15 Field test verified flexibility options from a DSO perspective
  Arnoud Rijneveld (Stedin) and Marijn Renting (Enexis, the Netherlands)

  Flexibility is an upcoming theme for DSOs. Some insights and first results of current test beds, of the Dutch DSOs Stedin and Enexis, which explore demand side management will be shared. Also, questions that still need to be answered in the Netherlands regarding DSM by DSOs, will be addressed.

• 11:30 Flexibility and Cost Benefit Analysis of the PowerMatchingCity-II Living Lab in Hoogkerk the Netherlands
  Elke Klaassen (Enexis, the Netherlands)

  Based on the results of the Dutch smart grid pilot PowerMatching City phase-II (45 house holds), we try to answer the question: what are the potential benefits of a large-scale implementation of PowerMatching City phase-II in the Netherlands? To do so, the measured data from the pilot was used to quantify the flexibility of the smart appliances (i.e. micro-CHPs, heat pumps and electric vehicles). Consequently, this flexibility is used as input for a model that represents the Dutch power system. To quantify the benefits both the energy market value and the grid value are assessed, using basic energy market simulations and load balance calculations respectively.

• 11:45 Demand response in the Smartgrid Gotland project
  Daniel Brodén (KTH Royal Institute of Technology)

  This talk presents preliminary results and studies from the Smart Grid Gotland Project. The focus of the talk is on subproject (i) wind power integration and (ii) market test and installation. Results from subproject (i) include simulation results on demand-response potential for congestion management. Results from subproject (ii) include lessons learned from an actual demand-response implementation and survey results on customer satisfaction.

• 12:00 Flexibility analysis and implications of the real time market concept of EcoGrid
  Matthias Stifter (Austrian Institute of Technology)

  One of the possible approaches to implement demand response is using a real-time market. Within the EcoGrid project, a real-time market place for distributed energy resources was implemented in a demonstration on the island of Bornholm in Denmark with considerable customer involvement. Flexibility and volume of demand response activated by real-time price signals will be discussed.

• 12:15 Regulatory Recommendations for the Deployment of Flexibility
  Werner Friedl (Austrian Institute of Technology)

  The report "Regulatory Recommendations for the Deployment of Flexibility" focuses on flexibility from distributed resources, including demand side participation, and seeks to identify flexibility services, relevant value chains, but also the necessary commercial and market arrangements, while it answers the question on how different actors can be incentivised to provide and use flexibility. Finally, concrete recommendations are provided to the European Commission, to policy makers and stakeholders, for removing regulatory barriers and incentivising the uptake of flexibility from distributed resources.
