Abstract

In the United States, 40% of the nation’s total energy consumption and 75% of the total electricity consumption consumed by commercial and residential buildings, and those numbers are projected to be 46% and 80% by year 2035. Primary energy source is limited, and quickly consumed in the modern world. A sustainable energy future and net zero energy buildings require high penetration of Renewable Energy Source (RES) such as wind and solar. However, the constrained availability and variability/intermittency of RES present a great challenge to integrate wind and solar energy into the power grid at a large scale. There is a huge potential for building energy cost savings through a proactive integration with the power grid. The key to improve building operation efficiency is to coordinate and optimize the operation of various energy sources with time-sensitive electricity price. In addition, Energy storage systems (e.g., electric battery, thermal storage from chilled water storage tank and building envelope thermal mass, etc.) increase the complexity of the whole system integration.

The intelligent building operation scheduling problem is formulated with the power grid, solar PV panels, electrical batteries as alternative energy sources, water tank and building envelope as thermal energy storage. The optimization is solved as a mixed integer programming problem. A platform of AMPL (A Modeling Language for Mathematical Programming) is used to for mathematical modeling and links to the optimization solvers. A case study shows that energy storage technologies provide an effective way to connect various energy supply resources and demands, and facilitate efficient and intelligent building operations.
