Dr. Jörg Petrasch, Vorarlberg University of Applied Sciences, Austria Bio : Jörg Petrasch received his M.S. and PhD in Mechanical and Process Engineering from ETH Zurich. His doctoral thesis on solar thermal reforming of methan, focusing on reactive flows in porous catalytic structures was carried out under the guidance of Prof. Aldo Steinfeld. He has worked as a numerical analyst and consulting engineer for the chemical, construction, and energy industry, contributing to a range of projects including the Gotthard Basistunnel and NAGRA, the Swiss Society for the Disposal of Nuclear Waste. In 2009 he joint the faculty of the University of Florida as an Assistant Professor. There, he helped to build a successful solar thermochemistry program culminating in a DOE ARPA-E award. Since 2012, he works as illwerke vkw Professor for Energy Efficiency and director of the Energy Research Center at the Vorarlberg University of Applied Sciences, Austria. Dr. Petrasch’s research interests are renewable energy carriers, dynamics of energy systems particularly demand side management, and multi-scale effects in energy systems. |

Abstract : Domestic hot water heaters are studied as a means for price-driven active demand side management. Optimization is based on a dynamic thermal model of water heater behavior. Model parameters are identified based on experimental data from a 150 l, 2.2 kW domestic hot water heater. Historic day ahead spot market prices from Austria’s EXXA energy exchange are used for carrying out the optimization. Fully deterministic, fully random and statistically realistic user behaviors are assumed. The yearly cost savings for fully deterministic behavior are 36.7 EUR compared to heaters without demand side management (DSM) and 24.9 EUR compared to heaters with traditional utility induced DSM. The yearly cost savings for statistically realistic user behavior are dependent on side conditions between 28.6 and 35.5 EUR compared to heaters without DSM and between 15.6 and 23.6 EUR compared to heaters with traditional utility induced DSM.
