Abstract
The research project aimed at developing a generic methodology to quantify the impact of distribution energy resources on a distribution grid. The methodology was applied on actual distribution grids and load data that consisted of two example distribution grids in rural (15000 customers, mostly residential), urban (almost 8000 customers, mostly flats and office buildings), and suburban areas (approx. 5000 customers, mostly detached and terraced houses).

The key outcomes of the project were:
  • Models of dynamic DER profiles for EV, BESS, and new heating solutions. 'Dynamic' means that the input parameters that define the shape of the profile can be easily varied.
  • Allocation of DER profiles to the end-customers depending on penetration rate and location.
  • Model of a distribution grid topology and dimensions for power flow simulations.
  • Analysis of the grid impact for various distribution grids and DER scenarios.
  • Model of multi-objective operation of BESS for FCR-N, self-consumption, and peak shaving tasks.
  • Representation of the grid impact range as a probability of its occurrence.
  • Quantitative results for case networks.
