Abstract: An energy storage system includes a photovoltaic energy field, a stationary energy storage device, an energy converter, and a controller. The photovoltaic energy field converts solar energy into electrical energy and charges the stationary energy storage device with the electrical energy. The energy converter converts the electrical energy stored in the stationary energy storage device into AC power at a discharge rate and supplies a campus with the AC power at the discharge rate. The controller predicts a required load of the campus and an electrical generation of the photovoltaic energy field across a time horizon and optimizes a cost function subject to a set of constraints to determine a discharge rate of the AC power to achieve a desired power factor. At least one of the set of constraints applied to the cost function ensures that the energy converter can convert the electrical energy stored in the stationary energy storage device into AC power having the determined power factor and discharge rate.

Abstract: A system for controlling a flow rate of a fluid through a valve is provided. The system includes a valve and an actuator. An actuator drive device is driven by an actuator motor and is coupled to the valve for driving the valve between multiple positions. The system further includes a differential pressure sensor configured to measure a differential pressure across the valve and a controller that is communicably coupled with the differential pressure sensor and the motor. The controller is configured to receive a flow rate setpoint and the differential pressure measurement, determine an estimated flow rate based on the differential pressure measurement, determine an actuator position setpoint using the flow rate setpoint and the estimated flow rate, and operate the motor to drive the drive device to the actuator position setpoint.

Abstract: A system for controlling a flow rate of a fluid through a valve includes a controller. The controller is configured to receive a raw flow rate measurement from a flow rate sensor assembly configured to measure the flow rate. The controller is further configured to apply a flow rate measurement filter to the raw flow rate measurement to generate a filtered flow rate measurement. The controller is further configured to control actuation of an actuator configured to change the flow rate using the filtered flow rate measurement. The controller is configured to automatically adjust the flow rate measurement filter in response to detecting an event that causes stoppage of the actuation of the actuator.

Abstract: A pressure disturbance rejection valve assembly is provided. The valve assembly includes a valve, a flow rate sensor, and an actuator. The actuator includes a motor, a drive device configured to be driven by the motor and coupled to the valve for driving the valve within a range of positions, and a position sensor configured to measure a rotational position of the drive device. The actuator further includes a communications mechanism configured to receive a flow rate setpoint and a processing circuit. The processing circuit is configured to determine an actuator position setpoint using a feedback control mechanism based on the flow rate setpoint and the flow rate measurement, operate the motor to drive the drive device to the actuator position setpoint, detect a fault condition based at least in part on the rotational position measurement or the flow rate measurement, and perform a fault mitigation action in response to detection of the fault condition.
