Assisting Renewable Energy Integration by Price Based Load Shifting using Heat Pumps with Thermal Storage

Inhalt:
Due to the ever-growing share of renewable energy generation in the electricity grid, different storage technologies will have to be used jointly together in the future. Against the background of a holistic approach, the electrical system is not to be considered on its own. Other energy carriers have also to be included in the sense of sector coupling. One possibility for short-term storage and simultaneous sector coupling is the use of heat pumps in combination with thermal storages. Simulations have shown that a price-based operation allows load shifts and can thereby support the integration of the fluctuating energy production provided by renewable generation units into the future energy system.
