Load management in smart grids with utilization of load-shifting potential in building climate control

Abstract

Operation safety in the smart grid can be secured by prescribing constraints on the power consumption of the end-users when considered necessary. In this paper a cohesive integration of the grid and building control is presented. First, a hierarchical model predictive control in smart grids for optimally calculating grid constraints is considered. Furthermore, in order to eff ciently incorporate grid constraints and still achieve admissible thermal comfort in the building, a model predictive control for building climate system with thermally activated building structure (TABS) is suggested. The load-shifting potential of the building with large thermal mass is demonstrated in simulations for various climate conditions on an example of an existing modern off ce building.
