In Germany, where 80  % of household energy goes to space heating and hot water, shifting to low-carbon solutions is crucial. Fossil-fuelled district heating networks can incorporate renewable energy via heat pumps, improving efficiency. Although heat pump design typically favours minimal temperature lifts, higher lifts can be economically viable with low electricity prices and abundant renewables. Adding thermal energy storage boosts operational flexibility. This study explores a flexible heat pump operation incorporating part load behaviour with a thermal energy storage in a German city’s district heating system to minimise costs and carbon dioxide emissions. Using a mixed-integer linear programming model, it examines the impact of temperature adjustments and storage on system efficiency. The results show that the integration of a heat pump in a district heating system reduces operating costs. Compared to a supply without a heat pump, with levelised cost of heating of 9.98 cent/kWhth and a fixed operating mode with costs between 9.96 cent/kWhth and 11.49 cent/kWhth, the flexible use results in lowest costs of 9.85 cent/kWhth, while also reducing overall CO2 emissions. Using a full factorial sensitivity analysis, the levelised cost of heating ranged between 9.15 cent/kWhth in the best case and 10.37 cent/kWhth in the worst case for the selected configuration.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://www.sciencedirect.com/science/article/pii/S0196890426006837"}],"article_number":"121714","doi":"10.1016/j.enconman.2026.121714","publication_identifier":{"issn":["0196-8904"]},"author":[{"id":"56955","full_name":"Rahlf, Henning Christoph","orcid":"0009-0006-8106-2132","last_name":"Rahlf","first_name":"Henning Christoph"},{"full_name":"Divkovic, Denis","last_name":"Divkovic","first_name":"Denis","id":"89059"},{"full_name":"Knorr, Lukas","first_name":"Lukas","orcid":"0009-0005-4727-7511","last_name":"Knorr","id":"90391"},{"id":"88614","last_name":"Schlosser","first_name":"Florian","full_name":"Schlosser, Florian"},{"id":"86954","first_name":"Henning","last_name":"Meschede","orcid":"0000-0002-1538-089X","full_name":"Meschede, Henning"}],"year":"2026","title":"Flexible operation strategies for heat pumps in district heating systems using dynamic electricity prices","intvolume":"       364","article_type":"original","date_updated":"2026-06-03T06:44:31Z","publication_status":"published","oa":"1","citation":{"chicago":"Rahlf, Henning Christoph, Denis Divkovic, Lukas Knorr, Florian Schlosser, and Henning Meschede. “Flexible Operation Strategies for Heat Pumps in District Heating Systems Using Dynamic Electricity Prices.” <i>Energy Conversion and Management</i> 364 (2026). <a href=\"https://doi.org/10.1016/j.enconman.2026.121714\">https://doi.org/10.1016/j.enconman.2026.121714</a>.","short":"H.C.

A relative method for the comparison of the proportion of the direct and indirect polarization transfer pathways is established, allowing a direct comparison of the polarization efficacy for different radicals and different parts of the 1-octanol molecule despite differences in radical concentration or sample amount. With this approach, it could be demonstrated that the hydrophilicity is a key factor in the way polarization is transferred from the polarizing agent to the analyte.

Consequently, those effects, i.e. the system’s dynamic behavior, need to be known. For the piezo-composite transducers in an ultrasonic transmission line, a model based approach is used to describe their dynamic behavior and take into account its dependence on the environment temperature and the acoustic impedance of the target medium. Temperature-dependent model parameters are presented, which are obtained by performing a multiplepart identification process on the transducer model, based on electrical impedance measurements [1]. The identification process uses an inverse approach for optimizing a subset of the model parameters. Additionally, algorithmic differentiation methods are used to determine accurate derivatives. In a final optimization step, impedance measurements taken at different temperatures are used to determine the temperature dependencies of the model parameters. These can then be used to assess the plausibility of the identification results. Additionally, the parameters can be expressed as polynomials in the temperature to take different operating conditions into account.","lang":"eng"}],"publication":"AMA Conferences 2015","citation":{"ama":"Webersen M, Bause F, Rautenberg J, Henning B.

Typical examples are crankshafts, camshafts, differential gear or hydraulic pumps. In the operating state the elastomeric seal ring and the shaft are separated by a lubrication film of just a few micrometers. Due to shear strain and fluid friction the contact area is subject to a higher temperature than the rest of the seal ring. The stiffness of the elastomeric material is intensely influenced by this temperature and thus contact pressure, friction and wear also strongly depend on the contact temperature. In order to simulate the contact behavior of elastomer seal rings it is essential to use a comprehensive approach which takes into consideration the interaction of temperature, friction and wear. Based on this idea a macroscopic simulation model has been developed at the MEGT. It combines a finite element approach for the simulation of contact pressure at different wear states, a semi-analytical approach for the calculation of contact temperature and an empirical approach for the calculation of friction.

A multitude of wheel--rail contact models exists, however, traction--creepage curves obtained from measurements show quantitative and qualitative deviations. There are several phenomena which influence the traction--creepage characteristics: Mechanisms resulting from surface roughness, frictional heating or the presence of interfacial fluids can have a dominating influence on friction. In this paper, a new wheel--rail contact model, accounting for these influential parameters, will be presented. The presented model accounts for the interaction of an interfacial fluid model for combined boundary and mixed lubrication of rough surfaces with a wheel--rail contact model that additionally accounts for frictional heating. A quantitative comparison with measurements found in the literature is not conducted, since the exact conditions of the measurements are mostly unknown and parameters can easily be adjusted to fit the measurements. Emphasis is placed on the qualitative behavior of the model with respect to the measurements and good agreement is found. The dependence of the maximum traction coefficient on rolling velocity, surface roughness and normal load is studied under dry and water lubricated conditions.","lang":"eng"}],"publication":"Wear","user_id":"55222","volume":271,"page":"2 - 12","_id":"9772","status":"public","quality_controlled":"1","citation":{"bibtex":"@article{Tomberger_Dietmaier_Sextro_Six_2011, title={Friction in wheel--rail contact: A model comprising interfacial fluids, surface roughness and temperature}, volume={271}, DOI={<a href=\"https://doi.org/10.1016/j.wear.2010.10.025\">10.1016/j.wear.2010.10.025</a>}, journal={Wear}, author={Tomberger, Christoph and Dietmaier, Peter and Sextro, Walter and Six, Klaus}, year={2011}, pages={2–12} }","ama":"Tomberger C, Dietmaier P, Sextro W, Six K.
