    Abstract: A controller for a plurality of interconnected devices in a system is shown. The controller includes a processing circuit configured to detect that a first device of the plurality of interconnected devices is unavailable and identify a second device of the plurality of interconnected devices schematically dependent upon the first device by conducting a graph theory analysis on schematic relationships indicating connections among the plurality of interconnected devices. The processing circuit is further configured to, in response to identifying the second device schematically dependent upon the first device, generate a reduced subset of the plurality of interconnected devices that excludes the second device. The processing circuit is further configured to operate the reduced subset to transfer one or more resources among the reduced subset via the connections.

    Abstract: Disclosed herein are related to a system, a method, and a non-transitory computer readable storing instructions for operating an energy plant comprised of heating, ventilation and air conditioning (HVAC) devices. In one aspect, the system generates gradient data indicating a gradient of operating performance of the energy plant with respect to values of a plurality of control variables of HVAC devices. The system determines, from the plurality of control variables, a reduced group of control variables of the HVAC devices based on the gradient data. The system determines a set of values of the reduced group of control variables. The system operates the energy plant according to the determined set of values of the reduced group of control variables.

    Abstract: Systems and methods for auto-commissioning and self-diagnostics of equipment in a building management system are provided. A self-testing module is implemented in a control unit of the building management system. The self-testing module exercises equipment of the building management system using a state-based testing procedure that differs from normal operation of the equipment and monitors feedback received from a sensor of the building management system in response to exercising the equipment. The self-testing module uses the feedback from the sensor to evaluate a state transition condition of the state-based testing procedure and to transition between states of the state-based testing procedure using a result of the evaluation.

    Abstract: A controller for equipment obtains utility rate data indicating a price of one or more resources consumed by the equipment to serve energy loads. The controller generates an objective function that expresses a total monetary cost of operating the equipment over an optimization period as a function of the utility rate data and an amount of the one or more resources consumed by the equipment at each of a plurality of time steps. The controller optimizes the objective function to determine a distribution of predicted energy loads across the equipment at each of the plurality of time steps. Load equality constraints on the objective function ensure that the distribution satisfies the predicted energy loads at each of the plurality of time steps. The controller operates the equipment to achieve the distribution of the predicted energy loads at each of the plurality of time steps.
