Munich, Germany — (METERING.COM) — March 28, 2011 – The Fraunhofer Institute for Solar Energy (Fraunhofer ISE) has announced the conclusion of a pilot project to demonstrate how smart metering systems with flexible tariffs for supply and loads can be used to intelligently control the load flow in the networks.
The project used the DEMAX (Decentralized Energy and grid MAnagement with fleXible energy rates) gateway, developed under the German Federal Ministry of Economics and Technology Innonet initiative, and Fraunhofer ISE’s developing openMUC software platform to optimally match the energy supply and demand for both thermal and the electrical energy.
“With the openMUC platform, we can record relevant billing data from electricity, gas, heating/cooling and water consumption in a modular way,” commented Christian Sauer, the project leader at Fraunhofer ISE. “The metering technology for single and multi-family houses can be kept to a minimum, i.e. cost effective.”
The project was realized with the SenerTec Dachs combined heat and power (CHP) system, and took place in Bad Bellingen, Germany using a distribution grid of project partner EWS Schönau Netze GmbH. Economic incentives such as time-of-use tariffs were determined for the system using an optimizing algorithm.
Other participants in the pilot included research partner Steinbeis Innovationszentrum – Embedded Design and Networking (sizedn), which tested and optimized its wireless M-Bus technology, SSV Software Systems GmbH, which developed the DEMAX communication module with a Linux-based embedded system, and Görlitz AG, which assisted in successfully integrating the energy data (EDW3000) into the business process of the relevant agents in the energy market.
With the flexible tariffs offered by EWS Schönau an average load shift of four percent was realized, and overall the pilot showed that decentralized players can actively participate in the energy market through the use of flexible electricity tariffs, according to Fraunhofer ISE.
