Abstract: Systems and methods for distributing load of an energy plant are disclosed herein. A target load of at least a first device and a second device of the energy plant is obtained. A first power consumption of the first device and the second device predicted to result from operating the first device and the second device according to a first combination of set points to satisfy the target load is predicted. A second power consumption of the first device and the second device predicted to result from operating the first device and the second device according to a second combination of set points to satisfy the target load is predicted. The first power consumption and the second power consumption are compared, and a combination of set points rendering lower power consumption is selected to operate the energy plant.

Abstract: An optimization system for a central plant includes a processing circuit configured to receive load prediction data indicating building energy loads and utility rate data indicating a price of one or more resources consumed by equipment of the central plant to serve the building energy loads. The optimization system includes a high level optimization module configured to generate an objective function that expresses a total monetary cost of operating the central plant over an optimization period as a function of the utility rate data and an amount of the one or more resources consumed by the central plant equipment. The high level optimization module is configured to optimize the objective function over the optimization period subject to load equality constraints and capacity constraints on the central plant equipment to determine an optimal distribution of the building energy loads over multiple groups of the central plant equipment.

Abstract: A method for testing a cooling component in a building HVAC system uses a state-based testing procedure. The method includes providing a control signal to the cooling component. The control signal instructs the cooling component to activate. The method includes monitoring feedback from a temperature sensor configured to measure temperature affected by the cooling component and evaluating a state transition condition by comparing the feedback from the temperature sensor to a threshold value. The state transition condition is satisfied if the feedback is less than the threshold value and not satisfied if the feedback is not less than the threshold value. The method includes transitioning into a pass state in response to the feedback from the temperature sensor satisfying the state transition condition and transitioning into a fail state in response to the feedback from the temperature sensor not satisfying the state transition condition.
