Dr. Anna Kallert is head of the research group “urban heat systems” at the Fraunhofer Institute for Energy Economics and Energy System Technology in Kassel (Germany). In 2018 she received her doctorate at the Technical University of Munich. As part of her dissertation, she developed an assessment methodology for the innovative district heating supply of districts and cities. Her research focusses on evaluation, simulation and optimization of low-temperature district supply concepts based on renewable energy sources.

Abstract:

The work is aimed at simulation, analysis and optimisation of innovative low temperature district heating (LTDH) supply solutions for a new development area in the city of “Neuburg an der Donau” (Germany). The LTDH supply is based on a decentralized heat pump using low temperature heat sources and decentralised PV systems. In developing and analysing of different supply options, local heat potentials and potentials of sector coupling are considered. In addition to the evaluation of technical boundary conditions, economic and regulatory aspects are also included in the investigations. The result of the work is the comparison of the efficiency of different district heating supply concepts and the development of different operating strategies considering regulatory framework conditions.
