In order to comply with climate goals in the future, all relevant sectors must implement extensive decarbonisation measures. For power system models, this implies that more complex interactions of bi-and multivalent technologies in the heat, industry and transport sector have to be included. Coupled with higher shares of renewable generation, these interactions lead to significant modelling challenges for large-scale power system models. Focusing on the heat sector, this study develops two aggregation methods for representing hybrid boilers, monovalent heat pumps and CHP systems in an adequate but computationally efficient way. The performance of the aggregation methods is evaluated and compared to the disaggregated reference case in terms of result accuracy and solution time for two load scenarios. It has been shown that the proposed aggregation method 2 which is based on the heating technology efficiencies yields a sound approximation of the disaggregated reference.
