Publikation Flexible capacity addition case study at reduced grid tariff without security of supply(2019) Layec, Vincent; Wache, HolgerEnergy intensive industries are sensitive both to the reliability and to the costs of their energy supply system. With renewable energy becoming more affordable, their weather dependent over- and under production will cause more volatile and higher spot price, but fees prevent the roll-out of Power- to-Gas. In this paper, we differentiate the new flexible loads of energy conversion and storage like Power-to-X or batteries from the regular loads of the core activity of industries and we design the tariff system of flexible loads in such a way to be financially attractive, by abandoning a security of supply that they actually do not need. In a previous work, the technical functionality of a load management system solving the grid congestion issues was described. Here we aggregate the yearly energy balance and the associated costs in six case studies to verify that the roll-out of the new flexible loads is economically viable. The financial attractiveness of the roll-out of new flexible loads with reduced tariff system and future drop in technology price is verified in all these customers and the tariff reduction for conditional loads is the decisive factor of the profitability in four of them.04B - Beitrag KonferenzschriftPublikation Smart metering applications. Main concepts and business models(Springer, 2022) Efkarpidis, Nikolaos; Geidl, Martin; Wache, Holger; Peter, Marco; Adam, MarcThis book presents a large number of smart metering applications from the points of view of different stakeholders. The applications are clustered with respect to three types of stakeholders: (a) end-customers, (b) energy service providers, and (c) authorities/research institutions or other organizations. The goal of the book is to examine the implementation potential for each application, considering the interests and benefits for the key stakeholders, main technical and regulatory requirements, as well as limitations and barriers. A business case for each application is created that can provide guidelines to the stakeholders involved in its realization. The book additionally investigates current business models for smart metering applications. A survey on the current techno-economic potential of such applications is conducted based on a questionnaire filled by various stakeholders. The book will be of interest to academic/research institutions, but also engineers in industry, authorities or other organizations.02 - MonographiePublikation Technoeconomic review of smart metering applications(Springer, 2023) Efkarpidis, Nikolaos; Geidl, Martin; Wache, Holger; Peter, Marco; Adam, Marc; Ould Abdeslam, DjaffarThis chapter represents a brief version of the survey conducted in Efkarpidis et al. (Smart metering applications: main concepts and business models. Springer Nature Switzerland, Basel, pp. 1–164, 2022), where various smart metering applications are presented from the point of different stakeholders’ interests.04A - Beitrag SammelbandPublikation AI meets Business Rules and Business Process Management(2008) Hinkelmann, Knut; Wache, HolgerBusiness rules and business process management are growing research and application areas for semantic technologies. While both areas make use of model driven knowledge representations?often in conjunction with application-oriented modeling tools?the potential of knowledge representations with precise semantics has only recently been recognized.Generally, the areas of ?business rules,? ?semantic technologies,? and ?business process management? are addressed by different communities at present. Standards are promoted by different organizations like W3C, OMG, and WfMC. Current research and practice, however, begins to identify and explore the benefits for combining methodologies from these different areas.Business rules, for example, strive to meet the increasing requirements of transparency and compliance, making sure that all stakeholders comply with all rules and regulations at any place and any time. Defining a commonly agreed vocabulary is a prerequisite for rule definitions.04B - Beitrag KonferenzschriftPublikation Cloud Broker: Bringing Intelligence into the Cloud - An Event-Based Approach(05.07.2010) Tripathi, Uttam Kumar; Wache, Holger06 - PräsentationPublikation Towards an Integrated Approach to Assess the Potential of an Enterprise to Mature Knowledge, 5th Conference Professional Knowledge Management - Experiences and Visions(Gesellschaft für Informatik, 25.03.2009) Brun, Roman; Hinkelmann, Knut; Telesko, Rainer; Thönssen, Barbara; Bludau, Hans-Bernd; Koop, Andreas; Hinkelmann, Knut; Wache, HolgerIn this paper we describe a multi-dimensional framework for knowledge maturing and learning. The framework consists of seven dimensions and supports the assessment of the knowledge management as-is-state in a company as well as the selection of appropriate approaches and methods for a further improvement. The paper also discusses the relationship to comparable approaches (e.g. intellectual capital statements) and ends with open issues for a proper implementation of the maturity framework.04B - Beitrag KonferenzschriftPublikation Relaxing RDF Queries based on User and Domain Preferences(Springer, 01.12.2009) Dolog, Peter; Stuckenschmidt, Heiner; Wache, Holger; Diederich, Jörg01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Enterprise Architecture Frameworks for Enabling Cloud Computing(26.08.2010) Tripathi, Uttam Kumar; Wache, Holger; Ebneter, Daniel; Stella Gatziu GrivasCloud computing has emerged as a strong factor driving companies to remarkable business success. Far from just being an IT level support solution cloud computing is triggering changes in their core business models by making them more efficient and cost-effective. This has generated an interest for a lot of companies to try and adopt cloud computing for their existing and new business process. In this research we present an approach which a company can use to analyze if its operations can be positively impacted by moving to the cloud. Further we describe our approach using which the company can make that transition to the cloud.04B - Beitrag Konferenzschrift
