[more ▼] 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.

[more ▼] 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.

[more ▼] 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 ▲] Detailed reference viewed: 50 (1 UL)Estimating the benefits of cooperation in a residential microgrid: a data-driven approachFridgen, Gilbert ; Rieger, Alexander ; et alin Applied Energy (2016), 180 Detailed reference viewed: 74 (8 UL)Blockchain: Fundamentals, Applications and Potential; ; et al Report (2016) Detailed reference viewed: 44 (0 UL)Providing Utility to Utilities : the Value of Information Systems Enabled Flexibility in Electricity ConsumptionFridgen, Gilbert ; ; et alin Journal of the Association for Information Systems (2016), 17(8), 537--563 Detailed reference viewed: 34 (3 UL)The Value of IS-Enabled Flexibility in Electricity Demand : A Real Options ApproachFridgen, Gilbert ; ; et alin 12th International Conference on Wirtschaftsinformatik (WI) (2015) Detailed reference viewed: 22 (1 UL)Investigation of Exogenous Shocks in Complex Supply Networks : A Modular Petri Net ApproachFridgen, Gilbert ; ; in International Journal of Production Research (2015), 53(5), 1387--1408 Detailed reference viewed: 28 (0 UL)Supply Chain Network Risk Analysis : A Privacy Preserving ApproachFridgen, Gilbert ; in Proceedings of the 23rd European Conference on Information Systems (2015) Detailed reference viewed: 32 (0 UL)Improving Business Value Assurance in Large-Scale IT Projects ?
