Modelling and simulation of future supply systemsC4DSI research – Center For Demand Side Integration
The rising percentage of renewable energies and the resulting increase in the amount of fluctuating electricity that is produced require that the existing energy system be restructured. Both electricity producers and consumers have to be able to react more flexibly to supply situations. The Center for Demand Side Integration (C4DSI) has taken on the challenge to research new approaches in this area. The C4DSI is a working group of the Institut für Informationstechnik und verteilte Systeme (“Institute of Information Technologies and Distributed Systems”, or ifit) at the Hamburg University of Applied Sciences. The core competencies are modelling and simulation: detailed models of decentralised production and consumption systems are carried over into a high-performance simulation platform. This enables a complex group of tens of thousands of individual systems to be simulated over long periods of time. Various organisational and communication structures are tested in the process – in the background, there is a vision of a decentralised supply system that organises and stabilises itself. Another focus of the interdisciplinary team is on the comprehensive inclusion of other forms of energy and networks. How can the electricity-based operation of a combined heat and power unit be optimised with the aid of more accurate heat requirement forecasts? Does it make more sense to feed excess wind power as heat into the local and district heating networks, or should it be used to produce hydrogen? The focus is always directed towards the profitability of different business models within the context of volatile energy markets. An example of this is the placement of large industrial consumers in the balancing energy market. The C4DSI is applying these competencies to several state, federal and EU-funded research projects while also collaborating with energy providers, industrial companies and public bodies. It is also an important partner of the Hamburger Energieforschungsverbund (“Hamburg Energy Research Association”) when it comes to developing the intelligence of smart grids.
