Building Energy Management Considering Nonlinearity of Electric Equipment with PV-Battery Systems during Power Outage

Optimization of energy management in office buildings is essential to get through power outages while continuing business operations. For this purpose, an accurate mathematical model of energy management is necessary. This study proposes a mathematical model for optimal building operation during power outages. The model is formulated using nonlinear functions with the number of workers on each floor and the power consumption of demand facilities as control variables and solved as a mixed integer linear programming method to minimize the damage that occurs during a power outage. Numerical experiments using actual building data verify the validity of the proposed method by comparing optimized human and facility operational plans using the proposed and conventional models.
