In the course of the German Energiewende, the share of controllable power generation is decreasing, while renewable, volatile generation resources (wind turbines and pho-tovoltaics), are being expanded. Therefore, the need for flexibility on the consumer side to compensate for this volatile generation is growing, because the balance of power production and power consumption needs to be guaranteed [1]. The German industrial sector consumes the largest share by 43.7 % of electricity [2] and also holds enormous potential for load flexibility in Germany [3]. However, many potentials cannot be ex-ploited because the necessary information technology connections are missing. The ge-neric data structure presented in this paper offers an approach to describe power flexi-bility potentials in a standardized way for a prevailing situation. This state-dependent flexibility potential can thus be made available to a higher-level instance for optimizing the operation strategy. As digitization progresses, the degree of automation increases, and so does the flexibility potential of the system. To this end, the basic characteristics of flexibility are first of all worked out and the corresponding degrees of freedom are explained in more detail. The existing approaches for describing flexibility of conven-tional power plants, such as the transmission code [4], will also be discussed. There are two classes of power flexibility - time-restricted and time-independent flexibility. Sep-arate sets of flexibility indicators are created for both classes, which are then transferred to a data structure. Finally, an information architecture to process the data model is presented.

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 possible 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. [less ▲]

This position paper analyzes blockchain technology from a scientific and application-oriented perspective of the Fraunhofer-Gesellschaft. It examines relevant technical aspects and related research questions. This shows that the technology still has fundamental research and development challenges in all areas. These include, for example, the modularization of individual blockchain concepts as well as their combination and integration for application-specific blockchain solutions. The investigation of fields of application and industries that can best benefit from the new technology shows that different properties of the blockchain are relevant for a field of application are. While the automation potential associated with smart contracts is essential for the Internet of Things, it is the irreversibility of the transactions managed for applications in the areas of supply chain, digital media or for guarantees of origin. However, the decisive aspect is that the blockchain is of great relevance for many different areas of application outside of the financial sector and, above all, independent of cryptocurrencies.

To date, research on smart cities has primarily focused on urban congested areas. As this paper points out, it is becoming ever more important to look at intermediate and thinly populated regions like towns and rural areas as arenas for digital innovation. By following a multi-phase research process, we examine towns’ highly individual needs in an exploratory way, derive key aspects from recent literature that can serve to mitigate or solve their problems, and present an open innovation process by way of integrating local context factors, local stakeholders, and suitable information and communication technology solutions. Our objective is to develop a first digital innovation approach in a field that has so far been scarcely considered. We conduct a case study which demonstrates the applicability and effectiveness of our innovation approach in a small town in southern Germany and derive first important lessons learned. Thereby, the concept of an innovation ecosystem reveals a promising solution to face the challenges of the investigated town. [less ▲]

Demand-side management and demand response are integral building blocks for environmental sus-tainability. Exchange-based power pricing serves as an economic mechanism to set incentives to shift demand to periods where prices are low. Low power prices also serve as an indicator for green(er) power, since high feed-ins from variable renewable sources push the electricity price downward. For businesses, minimizing electricity costs thus not only contributes to economic but also environmental sustainability. Hence, especially energy-intensive businesses can become greener and more competitive by integrating volatile electricity prices into their production planning activities. In this paper, we demonstrate that the length of the planning horizons is key to achieve more sustainable outcomes due to the trade-off between decision flexibility and information accuracy. Decision flexibility – i.e. the ca-pability to shift processes – increases with longer planning horizons. Information accuracy – i.e. price accuracy – increases with shorter planning horizons. Information Systems (IS) can help to balance this trade-off. We follow a data-driven approach and derive both actual and predicted electricity spot prices from historic electricity intraday market data in Germany. We find that decision flexibility and infor-mation accuracy affect the planning horizon as conceived. First results indicate that more sustainable outcomes are achieved with longer planning horizons.

Bringing Blockchain technology and business process management together, we follow the Design Science Research approach and design, implement, and evaluate a Blockchain prototype for cross-organizational workflow management together with a German bank. For the use case of a documentary letter of credit we describe the status quo of the process, identify areas of improvement, implement a Blockchain solution, and compare both workflows. The prototype illustrates that the process, as of today paper-based and with high manual effort, can be significantly improved. Our research reveals that a tamper-proof process history for improved auditability, automation of manual process steps and the decentralized nature of the system can be major advantages of a Blockchain solution for cross-organizational workflow management. Further, our research provides insights how Blockchain technology can be used for business process management in general. [less ▲]

Blockchain is rapidly evolving and there is an increasing interest in the technology in both prac-tice and academia. Recently, a blockchain use case called Initial Coin Offering (ICO) draws a lot of attention. ICO is a novel form of crowdfunding that utilizes blockchain tokens to allow for tru-ly peer-to-peer investments. Although, more than 4.5 billion USD have been invested via ICOs, the phenomenon is poorly understood. Scientific research lacks a structured classification of ICOs to provide further insights into their characteristics. We bridge this gap by developing a taxonomy based on real-world ICO cases, related literature, and expert interviews. Further, we derive and discuss prevailing ICO archetypes. Our findings contribute to theory development in the field of ICOs by enriching the descriptive knowledge, identifying design options, deriving ICO archetypes, and laying the foundation for further research. Additionally, our research pro-vides several benefits for practitioners. Our proposed taxonomy illustrates that there is no one-size-fits-all model of ICOs and might support the decision-making process of start-ups, investors and regulators. The proposed ICO archetypes indicate how common ICOs are designed and thus might serves as best practices. Finally, our analysis indicates that ICOs represent a valid alter-native to traditional crowdfunding approaches. [less ▲]

Interest in blockchain is growing rapidly and at a global scale. The potential to disrupt various industries is attributed to the emerging blockchain technology. Organizations and institutions have thus begun to examine the emerging the technology and its impact on their businesses. However, researchers and practitioners still lack a systematic approach to understand the po-tential of blockchain and to develop convincing use cases. We addressed this research gap by applying an action design research approach and situational method engineering to propose a method for the development of blockchain technology use cases. Following this approach, we iteratively evaluate and further develop the proposed method through application in four distinct industries. In a next research step, we now focus on a broader context and evaluate if our existing use case development method is applicable for other emerging technologies than blockchain. By doing so, we seek to broaden our evaluation, generalize our method, and support practitioners and researchers in better leveraging the opportunities of continuous digital transformation. [less ▲]

Residential microgrids are poised to play an important role in future distributed energy networks. However, energy retailers have yet to identify effective electricity tariffs to incorporate residential microgrids into the energy value chain. For this reason, we have chosen to analyze a set of twelve representative tariff options retailers might offer in the future. To examine their effects on load profiles and electricity bills, we set up a comprehensive empirical evaluation framework. Our analyses identify three important recommendations for residential microgrid pricing: First, energy retailers should not offer volumetric tariffs as they result in higher electricity bills, encourage sharp peak loads, and fail to fully allocate system costs. Second, they should also be cautious in offering time-varying and especially real-time rates. Although these rates promise slightly lower energy bills for microgrid operators, they can destabilize load profiles if retailers fail to simultaneously introduce peak-moderating capacity charges. Third, energy retailers should consider tariffs with capacity and customer charges, which we find to lower electricity costs, foster peak shaving, and facilitate stable cost allocation. [less ▲]

Die vorliegende Arbeit ist Teil des durch das Bundesministerium für Bildung und Forschung geförderten Forschungsprojektes Synchronisierte und energieadaptive Produktionstechnik zur flexiblen Ausrichtung von Industrieprozessen auf eine fluktuierende Energieversorgung (SynErgie). Ziel des Forschungsprojektes ist die Befähigung der energieintensiven Industrien in Deutschland, die Stromnachfrage dem zunehmend fluktuierenden Stromangebot anzupassen. In der Vergangenheit waren Stromsysteme in der Regel dahingehend ausgelegt, dass die Erzeugungsseite des Marktes an das zeitliche Verhalten des Verbrauchs angepasst war. Durch den verstärkten Ausbau volatiler erneuerbarer Energien unterliegt die Stromerzeugung jedoch unkontrollierbaren, wetterabhängigen Schwankungen, weshalb eine Flexibilisierung des Gesamtsystems zunehmend an Bedeutung gewinnt. Die in SynErgie betrachteten Industrieprozesse stellen dabei eine Teilmenge potenzieller Flexibilisierungsoptionen dar und können zur Lastanpassung an schwankende Erzeugung sowie zur Bereitstellung von Systemdienstleistungen und Entlastung der Netze beitragen. In einem liberalisierten, wettbewerblichen Strommarkt sind im Hinblick auf die Erschließung der Potenziale der Nachfrageflexibilität die marktlichen und regulatorischen Rahmenbedingungen von hoher Relevanz. Diese Studie beschreibt daher zunächst die Grundlagen des Strommarktdesigns und des konstituierenden gesetzlichen Rahmens. Dabei wird stets der Bezug zur Anwendung auf Industrieprozesse genommen und potenzielle Hemmnisse der Partizipation flexibler Nachfrageprozesse aufgearbeitet. Die Analyse bildet den Ausgangspunkt für die folgenden Arbeitspakete im Cluster IV und dient der clusterübergreifenden Information über den Status Quo der Marktstrukturen und regulatorischen Rahmenbedingungen. Neben der systematischen Aufarbeitung des marktlichen Rahmens werden die wissenschaftliche Literatur sowie bereits publizierte Studien zum Thema Nachfrageflexibilität (Demand Side Management und Demand Response) in einer Metastudie analysiert und zusammengefasst.

Information system (IS) have not only become indispensable in professional contexts, but can also serve as a platform for data-based interventions targeting issues for humanity. Providing individuals with concrete feedback on their current behavior has been shown to foster sustainable behavior. So far, research on the real-world impact and nderlying mechanisms of such IS-enabled interventions is scarce. In a randomized controlled field experiment with 1,423 participants, we systematically test the effect of different intervention strategies regarding their impact on energy consumption and user experience. We find a onservation effect of over 18% for the best treatment. In particular, the results suggest that small, seemingly harmless variations of IS design choices regarding numerical, normative, or emotional feedback can considerably affect behavioral outcomes (energy use). Potential explanations of observed behavior are given based on theories from psychology. The study delivers design implications for innovative IS artifacts that highlight the importance and necessity of taking cognitive processes into account. [less ▲]

Electricity market design varies across countries throughout Europe. Thereby the provision and remuneration of flexibility always takes place in short-term market segments. Taking into consideration the fundamental changes of the power system, this paper discusses options for the future short-term market design. We develop a conceptual basis for a possible integration of currently separated short-term market segments. Market segment integration (MSI) is defined as the interaction between and possible combination of market segments, i.e. intraday market (ID), congestion management (CM) and balancing market (BA). The paper especially focusses on two options, namely an integrated BA and CM market and an integrated ID and CM market. For these options we determine the basic design features. We propose a criteria catalogue which allows the evaluation of the market design options. Based on several criteria we discuss possible positive and negative consequences as well as potential solutions. [less ▲]

These days, due to the high level of interactions between individual projects, IT project portfolios are best described as IT project networks. While varied and frequent interactions between single IT projects create additional risks, they also generate the possibility of additional synergistic effects. This, however, is not reflected in current methods for IT project portfolio evaluation and project portfolio selection, which neither account for specific network characteristics nor do they clearly distinguish between the types of interaction and their effects. In this paper, we model resource synergies and dependencies within IT project networks by means of weighted, undirected and directed graphs and describe how alpha centrality allows for an assessment of both. We further illustrate the importance of accounting for network characteristics and the equal importance of distinguishing between resource synergies and resource dependencies. Our model can therefore be applied to gain practical insights on IT project portfolios [less ▲]
