Ancillary Services for Distribution Grid: Demand Response of Building Thermal Inertia case

This study works with the application of the Demand Response (DR) program in the residential building sector. DR helps to resolve many power system problems of Distributed Grid (DG) as the congestion in the generation, the lack of flexibility and the high electricity demand during the Peak Hours (PH). The DR is already largely applied in the industry sector. Nevertheless, in the residential building sector, which represents around 35 % of European energy consumption, its large intronization actually is possible due to systems of smart managing and metering, dispatching and automation. Buildings can reach supplemental economic benefits from participation in the DR program additionally to energy efficiency or/and building insulation improvement. This work studies the possibility of economic benefits from Ancillary Services (AS) DR program participation due to the Building Thermal Inertia (BTI). The real test case produced with the real smart home test platform demonstrates the considerable attractiveness of this AS method. It brings additional economic benefits for the final householders with the respect of thermal comfort of the building. For DG this method brings an additional gain of flexibility which it really needs to compensate the increasing large penetration of renewable energies.
