Buildings-to-Grid Integration with High Wind Power Penetration

This paper presents a framework to handle wind power production in the so-called Building-to-Grid (BtG) framework by using buildings demand flexibility. A stochastic dynamical BtG model is first developed by extending the existing BtG models to integrate wind power and explicitly formulating the interactions between the Transmission System Operator (TSO), Distribution System Operators (DSO), and buildings. Then, a novel unified BtG framework is formulated to handle the wind power by the demand flexibility of individual buildings together with the traditional reserve scheduling, which is in general hard to solve due to the unknown and unbounded distribution of wind power generation. Finally, a tractable robust reformulation together with probabilistic feasibility certificates is provided. Our simulation study shows that the proposed BtG flexibility framework can substitute with the traditional reserve scheduling without losing stability properties of the power grid and violating the buildings thermal comfort of occupants.
