Potential of electrical building heating as thermal energy storage in Sweden
Sammanfattning: The purpose of this Master thesis is to investigate the potential of using electricity based building heating as thermal energy storage in Sweden and its applications. Building data and statistics along with literature were the basis for data collection and processing. The work was then carried out by selecting a thermal energy storage model to represent different building types that are equipped with electricity based heating systems. This aggregate thermal energy storage model was applied to the Swedish building stock, historical weather data and typical thermal comfort zones. The power and energy capacity of the thermal energy storage were studied and the model was used to evaluate Demand Response (DR) both as Price Based DR and Emergency DR. This thesis gives an approximation of the potential of both power and energy capacity which has not been clearly quantified in previous studies for thermal energy storage in buildings of Sweden. The thesis was carried out for the Department of Energy Technology (EGI) at the Division of Electric Power and Energy Systems (EPE) in collaboration with SWECO as part of the North European Energy Perspectives Project (NEPP).
