Publication number: 20230400211Abstract: A control system includes an energy management system in operation with intelligent, network-connected thermostats located in structures. The thermostats are operable to control heating, ventilation, and air conditioning (HVAC) systems. Control during a demand response (DR) event period may be performed based on an optimal setpoint schedule of the HVAC system. Candidate setpoint schedules may be simulated to identify an optimal schedule.Type: ApplicationFiled: August 29, 2023Publication date: December 14, 2023Applicant: Google LLCInventors: Yoky Matsuoka, Mark Malhotra, Allen J. Minich, Mark D. Stefanski

Patent number: 10545517Abstract: In controlling the HVAC system, a need to determine an expected indoor temperature profile for a particular schedule of setpoint temperatures may arise. To make such a determination, a thermodynamic model of the structure is used. The thermodynamic model is generated by fitting weighting factors of a set of basis functions to a variety of historical data including time information, temperature information, and HVAC actuation state information. The set of basis functions characterize an indoor temperature trajectory of the structure in response to a change in HVAC actuation state, and include an inertial carryover component that characterizes a carryover of a rate of indoor temperature change that was occurring immediately prior to the change in actuation state.Type: GrantFiled: February 22, 2018Date of Patent: January 28, 2020Assignee: Google LLCInventors: Yoky Matsuoka, Mark Malhotra, Allen J. Minich, Joseph A. Ruff

Patent number: 9810442Abstract: Apparatus, systems, methods, and related computer program products for carrying out a demand response (DR) event via an intelligent, network-connected thermostat associated with a structure. The systems disclosed include an energy management system in operation with an intelligent, network-connected thermostat located at a structure. The thermostat is operable to control an HVAC system. Control during a DR event period may be performed based on an optimal control trajectory of the HVAC system, where the control trajectory is optimal in that it minimizes a cost function comprising a combination of a first factor representative of a total energy consumption during the DR event period, a second factor representative of a metric of occupant discomfort, and a third factor representative of deviations of a rate of energy consumption over the DR event period.Type: GrantFiled: April 19, 2013Date of Patent: November 7, 2017Assignee: Google Inc.Inventors: Yoky Matsuoka, Mark Malhotra, Allen J.
