  • Publication number: 20170219233
    Abstract: Aspects of the present disclosure describe a multi-layer chiller operation management framework and associated methods for managing heating, ventilation, and air conditioning (HVAC) multi-chiller unit operation in real time serving varying system loads. According to the present disclosure, the framework includes two layers—a first layer providing 24-hour chiller operation planning thereby optimizing chiller operation using forecasted load profiles to minimize energy consumption. To this is applied a mixed-integer linear programming (MILP) based optimization. A second layer adjusts chiller operation status in real-time based on actual system load demand. Load forecasting uncertainty is cured in a hierarchical manner based on the level of load uncertainty. Two approaches are employed namely rule-based load sharing adjustment and MILP-based rolling optimization.
