Abstract
The increase in electricity generation by renewable energy sources stimulated the implementation of new strategies and solutions such as demand side management (DSM), which were introduced to ensure the stability of the grid. In other words, these practices are applied to balance renewable energy production with electricity consumption. Based on a single-family house located in Egernsund, this master thesis focuses on the investigation of the load-shifting possibilities using DSM. It deep-dives into an analysis of an impact on the amount of energy load shifted to off-peak hours, and possible savings potential with a help of a heat pump, domestic hot water tank and buffer tank. Furthermore, the size of components and their dependence on the energy produced, the electricity consumption, temperature for domestic hot water and indoor comfort is investigated. The goal of this thesis is to present different simulations of the system configurations and heating setpoints, including electrical price signals as well as ‘’building as a battery’’ concept, to increase annual savings through load shifting, still maintaining the comfortable operative temperature as well as withdrawal tap temperatures.
