“…The reference scenario for the present work was taken from a previous study presented in [12]. Given the interest of a few housing associations (Section 1), the focus was to assess the technical Within the scope of the scenarios later described in Section 3, the buildings are grouped in 22 building blocks (BB) according to the energy declaration documents of the corresponding housing associations [29].…”

“…The importance of this study was stressed by a previous assessment that the installation of distributed HPs in Hammarby Sjöstad will cause overloadings on the local electricity distribution grid [12]. This was found by assuming that DSOs would impose a maximum loading limit equal to 100% for each grid's cable.…”

“…Given these literature gaps, one objective of this paper was to propose a district-level perspective on potential synergies among the heating, electricity, and transport sectors. To approach this sector-coupling problem, the co-simulations of dedicated models [12,28] and stochastic profiles were combined. Thus, the technical performances of technologies belonging to these different sectors were linked.…”

“…Here, the focus was on the case of a multi-apartments neighborhood located in Stockholm, Hammarby Sjöstad. By taking into account that distributed HPs can overload the local grid (reference scenario from [12] as a main objective, this paper aimed at estimating the potential of V2G to alleviate this problem (V2G integration scenario). This was done by using the energy stored in the EV's batteries to shave the HPs' peak power demand.…”

The city of Stockholm is close to hitting the capacity limits of its power grid. As an additional challenge, electricity has been identified as a key resource to help the city to meet its environmental targets. This has pushed citizens to prefer power-based technologies, like heat pumps and electric vehicles, thus endangering the stability of the grid. The focus of this paper is on the district of Hammarby Sjöstad. Here, plans are set to switch from district heating to heat pumps. A previous study verified that this choice will cause overloadings on the electricity distribution grid. The present paper tackles this problem by proposing a new energy storage option. By considering the increasing share of electric vehicles, the potential of using the electricity stored in their batteries to support the grid is explored through technical performance simulations. The objective was to enable a bi-directional flow and use the electric vehicles' (EVs)' discharging to shave the peak demand caused by the heat pumps. It was found that this solution can eliminate overloadings up to 50%, with a 100% EV penetration. To overcome the mismatch between the availability of EVs and the overloadings' occurrence, the minimum state of charge for discharging should be lower than 70%.
