SYSTEMS AND METHODS FOR CONTROLLING ENERGY USE IN A BUILDING MANAGEMENT SYSTEM USING ENERGY BUDGETS

摘要

Systems and methods for limiting power consumption by a heating, ventilation, and air conditioning (HVAC) subsystem of a building are shown and described. A mathematical linear operator is found that transforms the unused or deferred cooling power usage of the HVAC system based on pre-determined temperature settings to a target cooling power usage. The mathematical operator is applied to the temperature settings to create a temperature setpoint trajectory expected to provide the target cooling power usage.

1. A method for controlling power consumption of a building HVAC system, the method comprising:
using a controller of the HVAC system to calculate a deferred power usage resulting from a setpoint trajectory for a first time period; finding a target deferred power usage for a second time period subsequent to the first time period; finding a linear operator that transforms the deferred power usage for the first time period into the target deferred power usage; and applying the linear operator to the setpoint trajectory for the first time period to create a setpoint trajectory for the second time period.
