Kapacitetsutnyttjande för Power-to-Heat i svenska fjärrvärmesystem : En studie med befintliga anläggningar i framtida energisystem

The installation of variable renewable energy sources has rapidly increased during the last decade in several countries. It is likely that it will also increase in Sweden. Such a development could lead to periods of very high power production. In order to keep the stability of the electric grid, curtailment is the most common feed-in management method. This study examines how Power-to-Heat can utilize this surplus power in Swedish district heating systems instead of using curtailments and thereby facilitate the development of installed variable renewable energy sources. During this study a model was developed in MatLab where the capacity utilization was simulated for Power-to-Heat. The study indicates that the capacity utilization varies from 1,1–4,2 TWh electricity. In this scenario a share of the base load is substituted with new installed wind and solar power; 50 TWh respectively 10 TWh. The parameter that showed greatest sensitivity for the analysis were how the net power profile was simulated.
