      abstract     = {The transition towards coupled energy sectorswithin
                      multi-energy systems (MES) requires explicit modellingof
                      more components and thus requires careful decisions on
                      thelevel of modelling details. The focus commonly lies on
                      one energysector, with strong simplifications for the
                      remaining coupledenergy sectors. However, the impact of
                      model choice on the MESplanning solution is largely
                      unexplored. This work therefore setsout to investigate the
                      impact of component model choice in anMES with electricity
                      and heat for sizing a community batteryenergy storage system
                      (BESS). Our analysis examines the impactof the choice of
                      model of the power grid, the heating network, theheat pump,
                      and the thermal building. Our results show a 49 $\%increase$
                      in BESS size when using the convex second-order
                      coneformulation compared to the exact nonlinear AC OPF
                      equationsfor the power grid. The linear formulation results
                      in 58 $\%oversizing$ and suboptimal placement of the BESS.
                      Furthermore,explicitly modelling the heating network does
                      not significantlyimpact the design results but increases the
                      computational efforts.Different heat pump models show
                      minimum impact on the BESSdesign and location, thus our
                      findings suggest that linear modelsfor the heat pump are
                      suitable. However, omitting thermaldemand and storage
                      capabilities overestimates the BESS sizeby 42 $\%.$ This
                      further emphasizes the necessity of explicitlymodelling the
                      coupled heating sector and its thermal inertia forrealistic
                      electrical storage designs.},
