Multi-layer Optimized Coordination of Smart Building Resources in Active Power Distribution Systems

This paper proposes a multi-actor coordination platform for the optimal utilization of smart buildings resources, including roof top PV generation and battery energy storage system (BESS), in active power distribution systems. The proposed multi-actor coordination includes the Smart Building Coordinator (SBC), Micro-Grid Coordinator (MGC) and Distribution System Coordinator (DSC). The coordinators operate independently and only exchange limited information with each other to reach an optimal solution. In the proposed platform, a hierarchical optimization problem is solved to optimally determine the operating point of all distribution system resources. The proposed platform fully preserves the confidentiality of the behind the meter (BTM) data of the buildings since no information about the status of the PV system, BESS, and load of the building is shared with the owner of the power system. The proposed platform has a flexible and scalable architecture where the computational task of coordinating microgrids and smart buildings with distribution grid is performed locally at the MGC and SBC layers, respectively. Numerical simulations show the efficacy of the proposed platform in coordinating the BTM resources with the rest of the distribution system.
