Abstract: Systems and methods for distributing load of an energy plant are disclosed herein. A target load of at least a first device and a second device of the energy plant is obtained. A first power consumption of the first device and the second device predicted to result from operating the first device and the second device according to a first combination of set points to satisfy the target load is predicted. A second power consumption of the first device and the second device predicted to result from operating the first device and the second device according to a second combination of set points to satisfy the target load is predicted. The first power consumption and the second power consumption are compared, and a combination of set points rendering lower power consumption is selected to operate the energy plant.

Abstract: A central plant includes a plurality of subplants including a chiller configured to output supply water at a supply water temperature, a sensor configured obtain a measurement of the supply water temperature, and a control system. The control system is configured to calculate an additional load factor based on the measurement of the supply water temperature and a supply water temperature setpoint, obtain an actual load for the chiller, calculate an effective load based on the additional load factor and the actual load, generate load allocations for the plurality of subplants based on the effective load, and control the plurality of subplants to operate in accordance with the load allocations.
