Abstract: A method includes generating a duty cycle expression for heating, ventilation, air condition (HVAC) systems. The method includes estimating a baseline cycling percentage that maintains an indoor temperature at a particular setpoint based on the generated duty cycle expression and a curtailed cycling percentage that maintains the indoor temperature within a particular temperate interval of the particular setpoint. The method includes calculating a baseline-off-duration in which the HVAC system is in an off state during a normal operating cycle and a curtailed-on-duration implemented during a curtailment period. The method includes adjusting the curtailed-on-duration and the baseline-off-duration to satisfy a minimum-time-on and a minimum-time-off constraint of each HVAC system. The method includes identifying one or more HVAC systems to include in a micro DR event.

Abstract: Power distribution apparatus with input and output power sensing and a method of use. A power distribution unit includes a sensor that senses power parameters of power outputs and a power input, a processor, and a communication circuit. A power management system includes a power manager, a user interface, and a plurality of power distribution units that may be located in one or more equipment cabinets and data centers. The system may compute apparent power, RMS power, power factor, energy usage over time, power usage history, or environmental history for any or all of the power distribution units. The system may identify an under-utilized server connected to one of the power distribution units and initiate a shut-down of that server.
