Abstract

A cascaded control system is configured to control power consumption of a building during a demand limiting period. The cascaded control system includes an energy use setpoint generator and a feedback controller. The energy use setpoint generator is configured to use energy pricing data and measurements of a variable condition within the building to generate an energy use setpoint during the demand limiting period. The feedback controller is configured to use a difference between the energy use setpoint and a measured energy use to generate a control signal for building equipment that operate to affect the variable condition within the building during the demand limiting period.

Systems and methods for controlling energy use during a demand limiting period

Patent Wenzel, Michael J.; Drees, Kirk H.

Systems and methods for limiting power consumption by a heating, ventilation, and air conditioning (HVAC) subsystem of a building are shown and described. A feedback controller is used to generate a manipulated variable based on an energy use setpoint and a measured energy use. The manipulated variable may be used for adjusting the operation of an HVAC device.

Frequency based electric vehicle charge controller system and method for implementing demand response and regulation services to power grid using frequency detection

Patent Koritarov, Vladimir

Frequency responsive charging for plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV), a frequency sensing charging system and a method are provided for implementing demand response and regulation services to power grid using frequency detection for a frequency-based charge controller for plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV). A frequency of the power grid is continuously monitored and compared to a predefined tolerance band by a frequency sensor. Responsive to the frequency being outside the predefined tolerance band, the frequency is applied to a programmable logic controller. The programmable logic controller uses the applied frequencymore » « less

Systems and methods for controlling energy use in a building management system using energy budgets

Patent Wenzel, Michael J.

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.
