In the context of European climate goals municipalities have an increasing interest in an accurate estimation of current and future energy demand in buildings, as the domestic energy consumption is one of the major adjusting screws for the reduction of electrical and thermal energy consumption, whereas the demand for space heating has the highest impact. As part of the ongoing GEWISS project it is...
Currently, bike-sharing systems undergo a rapid expansion due to technical improvements in the operation combined with an increased environmental and health awareness of people. When it comes to the acceptance of such systems the reliability is of great importance. It depends heavily on the availability of bicycles at the stations. But, in spite of truck-based redistribution efforts by the operators,...
A key requirement for the realization of moderndistributed systems is their ability to dynamically adapt theirbehavior to changing environmental conditions to preserve theiroperation even in the presence of uncertain changes. In orderto accomplish this, the different parts of such a self-organizingsystem have to be coordinated to achieve meaningful adaptations. To avoid single point of failures, decentralized...
The growing dissemination of distributed energy resources with steadily changing power flows in combination with the rising demand for electricity leads to increasing problems in grid management. Planning and managing these resources with information and communication technology as well as automation technology for optimal operational planning while maintaining the system's security and stability...
The Smart Grid is a paradigm shift towards a bidirectional energy and communication system relying on rich information exchange among all involved actors. Based on the experience of the participation in the CEN-CENELEC-ETSI Smart Grid Coordination Group (SG-CG) report creation1 for the EU-Mandate 490 "European Smart Grid Standardization" [1], the EU-funded research project "Open System...
In the ongoing GEWISS project it is planned to implement a geographical heat information and simulation system. It shall provide a planning and simulation tool for the interlinking of urban development and district heating network development to support the political decision making process in the City of Hamburg. The system shall combine macroscopic and microscopic simulations to a co-simulation...
A key requirement to realize modern distributed systems is the ability of systems to autonomously adapt their behavior to changing environmental conditions at runtime, to preserve their operation even in the presence of uncertain changes. In order achieve this, the different parts of such a self-organizing system have to be coordinated to achieve meaningful adaptations. To avoid single point of failures,...
Dynamic and volatile grid conditions caused by the growing amount of renewable energy producers require the operation of large-scale distributed Demand-Side Management (DSM) applications. This is one of the tasks of the aggregator role in smart grid operation according to the Smart Grid Architecture Model (SGAM). For the optimization of distributed demand-side loads under such conditions, Multi-Agent...
The current development in the energy sector leads towards decentralized and distributed power generation. The coordination of the small- and medium-scaled distributed energy resources (DER) as well as further energy services will be a major challenge in smart grids. Many operation concepts like the Virtual Power Plant or microgrid operation will contribute to solve these serious problems for grid...
