Increasing Load Flexibility and Plant Dynamics of Thermal Power via the Implementation of Thermal Energy Storages

The significant increase of fluctuating renewables leads to great challenges for the power grids and for the power suppliers: the flexibility of their power plants has to rise to be sufficiently competitive. For thermal power plants the integration of thermal energy storages (TES) seems to be a promising approach. Therefore the so called sandTES technology, an active particle based TES system, is introduced. In a second step it is used to demonstrate the flexibility enhancement via TES integration. Thereby a novel concept for integrating this type of TES is presented and afterwards discussed. The results give an overview about the chances and restrictions of this implementation concept.
