van der Holst, B. (author), Verhoeven, G. (author), Nguyen, P. (author), Kok, K. (author), Emde, M.F. (author), Nutma, J.S. (author), la Fleur, S. (author)The increasing number of full-electric heat pumps (HPs) could potentially lead to congestion issues in future distribution grids. However, most modern HPs have the possibility to reduce demand during expected congestion events in a flexible manner. This study proposes a new approach for characterizing the potential downward flexibility of full...conference paper 2023

Rijvers, L. (author), Rindt, C. (author), de Keizer, A.C. (author)Photovoltaic-thermal (PVT) collectors are hybrid solar collectors that convert solar and ambient energy into thermal and electrical energy. Integrated PVT-HP, in which PVT collectors are combined with a heat pump, offers an efficient and renewable option to replace conventional fossil fuel-based energy systems in residential buildings. Currently...article 2022

Kamphuis, I.G. (author), Wijbenga, J.P. (author), van der Veen, J.S. (author)Software agent-based strategies using micro-economic theory like PowerMatcher[1] have been utilized to coordinate demand and supply matching for electricity. Virtual power plants (VPPs) using these strategies have been tested in living lab environments on a scale of up to hundreds of households. So far, the coordination configuration of a VPP is...conference paper 2016

Hu, J. (author), Poliakov, E.V. (author)We estimate the rebound effect for residential space heating at the EU-27 level, which occurs when an improvement in energy efficiency results in additional energy consumption. Three types of rebound effects are distinguished, namely the direct effect, indirect effect and the embodied energy. We demonstrate that the magnitude of the direct...other 2015

van Pruissen, O.P. (author), van der Togt, A. (author), Werkman, E. (author)For the built environment it is envisaged that in the near future the total annual heat demand could be covered by renewable sources generated within the built environment. More and more devices, such as heat pumps and solar collectors will enable a sustainable and distributed generation of heat. Centralized climate management systems are...article 2014

van Pruissen, O.P. (author), Kamphuis, V. (author), van der Togt, A. (author), Werkman, E. (author)In the near future an increase of both thermal grids and sustainable suppliers of heat with intermittency behavior, connected to these heat grids, is expected. For smart operation this challenges the current centralized management systems. To deal with this and to optimize cost and energy efficiency a multi-agent approach is proposed, which to a...conference paper 2013
