Conceptual framework for a multi-building peak load management system

Abstract

A building energy management (BEM) system serves as the key element of a smart building. It facilitates grid interaction and participation of a building in a demand response (DR) program. Typically, a BEM has been designed to manage loads in a single building. However, in reality, a number of adjacently located buildings can be owned by a single entity, like a campus. In this case, during DR events, instead of optimized control of loads in a single building, the coordinated control of loads in multiple buildings should be conducted to ensure the best operation condition for the entire facility. This paper proposes a conceptual framework to coordinate the operation of loads in multiple buildings, thereby reducing the peak demand of the entire facility during a DR event while minimizing occupant discomfort. Simulation results indicate that the proposed framework for coordinated control of multiple buildings results in less occupant discomfort than controlling loads in each building individually.
