2020 , Roth, Stefan , Schott, Paul , Ebinger, Katharina , Halbrügge, Stephanie , Kleinertz, Britta , Köberlein, Jana , Püschel, Danny , Buhl, Hans Ulrich , Ober, Steffi , Reinhart, Gunther , Roon, Serafin von

Economic solutions for the integration of volatile renewable electricity generation aredecisive for a socially supported energy transition. So-called energy-flexible factories can adapt theirelectricity consumption process efficiently to power generation. These adaptions can support thesystem balance and counteract local network bottlenecks. Within part of the model regionAugsburg, a research and demonstration area of a federal research project, the potential, obstacles,effects, and opportunities of the energy-flexible factory were considered holistically. Exemplaryflexibilization measures of industrial companies were identified and modeled. Simulations wereperformed to analyze these measures in supply scenarios with advanced expansion of fluctuatingrenewable electricity generation . The simulations demonstrate that industrial energy flexibility canmake a positive contribution to regional energy balancing, thus enabling the integration of morevolatile renewable electricity generation. Based on these fundamentals, profiles for regional marketmechanisms for energy flexibility were investigated and elaborated. The associated environmentaladditional expenses of the companies for the implementation of the flexibility measures wereidentified in a life-cycle assessment, with the result that the negative effects are mitigated by theincreased share of renewable energy. Therefore, from a technical perspective, energy-flexiblefactories can make a significant contribution to a sustainable energy system without greaterenvironmental impact. In terms of a holistic approach, a network of actors from science, industry,associations, and civil society organizations was established and actively collaborated in atransdisciplinary work process. Using design-thinking methods, profiles of stakeholders in theregion, as well as their mutual interactions and interests, were created. This resulted in requirementsfor the development of suitable business models and reduced regulatory barriers.

Simulation-based analysis of energy flexible factories in a regional energy supply system

2019 , Roth, Stefan , Thimmel, Markus , Fischer, Jasmin , Schöpf, Michael , Unterberger, Eric , Braunreuther, Stefan , Buhl, Hans Ulrich , Reinhart, Gunther

In a decentralized and renewable energy system, reliable and economical solutions are necessary to adjust power demand to a volatile power supply by photovoltaic and wind energy plants. A high potential for the balancing of short and medium-term power supply fluctuations is seen in energy flexible factories. To leverage this potential, monetary incentives and technological enablers have to be developed. Apart from that, the ecological and social aspects of energy flexible factories have to be considered in transdisciplinary research, to achieve a broad public acceptance. To assess the complex interrelations between the technical, political, legal and social sector, a clear and accessible base for discussions is necessary. This paper presents an approach for a simulation based-analysis of energy flexible factories with focus on high applicability and comprehensibility for stakeholders from different disciplines. This paper presents the general structure of the simulation model including the operation module for the energy flexible region Augsburg.

Konzept der Energiesynchronisationsplattform. Diskussionspapier V3

2020 , Reinhart, Gunther , Bank, Lukas , Brugger, Martin , Hieronymus, Aljoscha , Köberlein, Jana , Roth, Stefan , Bauernhansl, Thomas , Sauer, Alexander , Bauer, Dennis , Kaymakci, Can , Schel, Daniel , Schlereth, Andreas , Fridgen, Gilbert , Buhl, Hans Ulrich , Bojung, Caroline , Schott, Paul , Weibelzahl, Martin , Wenninger, Simon , Weigold, Matthias , Lindner, Martin , Ronge, Karlheinz , Oeder, Andreas , Schimmelpfennig, Jens , Winter, Christian , Jarke, Matthias , Ahrens, Raphael

Das Kopernikus-Projekt SynErgie entwickelt eine IT-Plattform, die automatisierten und standardisierten Handel mit industriell bereitgestellter Energieflexibilität ermöglichen soll. Wie diese Plattform funktionieren könnte, zeigt das Diskussionspapier ""Konzept der Energiesynchronisationsplattform"": Die zunehmende Nutzung von Strom aus erneuerbaren Quellen führt aufgrund der Wetterabhängigkeit von Wind und Sonne zu einem zunehmend volatileren Stromangebot. Damit das notwendige Gleichgewicht von Angebot und Nachfrage im Elektrizitätssystem jederzeit gewährleistet werden kann, sind Maßnahmen zum Ausgleich dieser Schwankungen notwendig. Energieintensive Industrieprozesse beinhalten ein hohes Flexibilitätspotenzial, um mittels Demand-Response, diesen Schwankungen zu begegnen. SynErgie arbeitet daran, den gesamte Prozess des Energieflexibilitätshandels von der Maschine bis an die Märkte auf einer IT-Plattform zu automatisieren und zu standardisieren. Die Energiesynchronisationsplattform besteht aus zwei logischen Teilplattformen, einer Markt- und vielen Unternehmensplattformen. Ziel bis Mitte 2022 ist es, ein durchgängiges Konzept einschließlich des Daten- und Informationsflusses von der Maschine bis zu den Energiemärkten zu entwickeln und in einer Referenzarchitektur abzubilden. Außerdem soll das Konzept im Rahmen einer Vielzahl von Forschungs- und Industriedemonstratoren und insbesondere in der Modellregion Augsburg mit lokalen Akteuren in einem umfassenden Testbetrieb erprobt werden. Mehr zur Energiesynchronisationsplattform, der Markt- und Unternehmensplattform, zur Informationssicherheit der IT-Plattformen, Anwendungsbeispielen und den Zukunftsvisionen können Sie im Diskussionspapier nachlesen.

Harnessing the Full Potential of Industrial Demand-Side Flexibility: An End-to-End Approach Connecting Machines with Markets through Service-Oriented IT Platforms

2019 , Rösch, Martin , Bauer, Dennis , Haupt, Leon , Keller, Robert , Bauernhansl, Thomas , Fridgen, Gilbert , Reinhart, Gunther , Sauer, Alexander

The growing share of renewable energy generation based on fluctuating wind and solar energy sources is increasingly challenging in terms of power grid stability. Industrial demand-side response presents a promising way to balance energy supply and consumption. For this, energy demand is flexibly adapted based on external incentives. Thus, companies can economically benefit and at the same time contribute to reducing greenhouse gas emissions. However, there are currently some major obstacles that impede industrial companies from taking part in the energy markets. A broad specification analysis systematically dismantles the existing barriers. On this foundation, a new end-to-end ecosystem of an energy synchronization platform is introduced. It consists of a business-individual company-side platform, where suitable services for energy-oriented manufacturing are offered. In addition, one market-side platform is established as a mediating service broker, which connects the companies to, e.g., third party service providers, energy suppliers, aggregators, and energy markets. The ecosystems aim at preventing vendor lock-in and providing a flexible solution, relying on open standards and offering an integrated solution through an end-to-end energy flexibility data model. In this article, the resulting functionalities are discussed and the remaining deficits outlined.

Extending the Automation Pyramid for Industrial Demand Response

2019 , Körner, Marc-Fabian , Bauer, Dennis , Keller, Robert , Rösch, Martin , Schlereth, Andreas , Simon, Peter , Bauernhansl, Thomas , Fridgen, Gilbert , Reinhart, Gunther

Industrial demand response uses a multitude of energy flexibility measures. Their planning and control requires various production IT systems. A widely accepted approach to classify these inhouse IT systems are the levels of the automation pyramid in companies. This paper broadens the scope of this concept to overcome the limitation to companies' (virtual) borders by including required IT systems that refine and monetarize a company's energy flexibility, e.g. energy markets, aggregators, etc. Therefore, a holistic approach for the classification of functionalities for industrial demand response across companies and energy markets is developed and applied exemplarily.

Flexible IT Platform for Synchronizing Energy Demands with Volatile Markets

2018 , Schott, Paul , Ahrens, Raphael , Bauer, Dennis , Hering, Fabian , Keller, Robert , Pullmann, Jaroslav , Schel, Daniel , Schimmelpfennig, Jens , Simon, Peter , Weber, Thomas , Abele, Eberhard , Bauernhansl, Thomas , Fridgen, Gilbert , Jarke, Matthias , Reinhart, Gunther

Abandoning fossil and nuclear energy sources in the long run and increasing amount of renewable energies in electricity production causes a more volatile power supply. Depending on external realities, renewable energy production emphasizes the need for measures to guarantee the necessary balance of demand and supply in the electricity system at all times. Energy intensive industry processes theoretically include high Demand Response potentials suitable to tackle this increasing supply volatility. Nevertheless, most companies do not operate their production in a flexible manner due to multiple reasons: among others, the companies lack know-how, technologies and a clear business case to introduce an additional level of flexibility into their production processes, they are concerned about po ssible impacts on their processes by varying the electricity demand and need assistance in exploiting their flexibility. Aside from fostering knowledge in industry companies, an IT-solution that supports companies to use their processes Demand Response potential has become necessary. Its concept must support companies in managing companies energy-flexible production processes and monetarize those potentials at flexibility markets. This paper presents a concept, which integrates both companies and energy markets. It enables automated trading of companies Demand Response potential on different flexibility markets.
