Integrated multi energy optimization for sector coupling decarbonation

In order to decarbonize energy systems, distributed renewable generation sites are being integrated into power distribution grids. This causes important grid constraints, which are typically satisfied by grid reinforcements. This paper aims to investigate if coupling a distribution grid with a district heating network could mitigate reinforcement needs while lowering district heating’s carbon footprint. The results of the considered case studied indicate that grid coupling can avoid reinforcements or curtailment caused by photovoltaic integration.
