Performance Simulations of Different Energy Flexibility Sources in a Building with the Electrical Grid

Abstract

In this paper, simulations of the performance of a building that has different energy flexibility sources is conducted. The building is a simulated single-family house located in Helsinki-Finland. The building’s energy system components include on-site energy generation from renewable energy (PV panels, solar thermal collector and a small wind turbine), energy storage (electric battery and a hot-water storage tank HWST) and heating devices (ground-source heat pump and electric heater), interacting with a bidirectional electric grid.
