Managing flexibility of power consumption of smart buildings on microgrid

This paper proposes a contract based mechanism to ensure the optimal management of a microgrid including smart buildings and local generation. The aim is to find a trade-off between the microgrid management system (MGMS) and the building energy management systems (BEMS) while preserving the building privacy. In this approach, the MGMS guaranties the prices of energy for buildings and the BEMS provides upward and downward flexibility proposals that can be activated by the MGMS. The exchanges between the two management systems are standardized and independent of the mechanism used by the BEMS to provide flexibility. The framework is implemented for electric heating buildings and an example is provided.
