摘要:
A distributed control node enables monitoring of complex energy signatures for local loads. The control node can identify energy signatures unique to local loads. The energy signature includes a complex current vector for the load in operation identifying the primary current with a real power component and a reactive power component, and identifying one or more harmonics each with a real power component, a reactive power component, and an angular displacement relative to the primary current. Based on the energy signature, the control node can control a noise contribution of the load due to the harmonics as seen at a point of common coupling to reduce noise introduced onto the grid network from the load.

Techniques for controlling dispatch of electric vehicles (EVs) to perform vehicle-to-grid regulation of power of an electric grid are presented. An aggregator component can individually control transitioning respective EVs of a set of EVs between a charging state and a not-charging state. The aggregator component includes a dispatch controller component (DCC) that can employ a defined dispatch algorithm for EVs to facilitate enabling the DCC to perform unidirectional regulation. The DCC can switch EV charging stations on and off using remote switches to meet a system regulation signal. The DCC can use the dispatch algorithm to make determinations regarding which EV to switch using charging priorities, in accordance defined power regulation criterion(s). The aggregator component can reduce communication signals used to adjust dispatch by sending switching signals to only those EVs of the set of EVs that are changing their charging state at a given time.

Systems and methods for automated fault detection in a building management system are shown and described. The systems and methods further involve organizing the data set into bins, each bin containing a plurality of the observed points for the variable of the building management system. The systems and methods further involve calculating, for each bin, a target parameter and an estimator of scale for the observed points. The systems and methods further involve detecting, for each bin, an outlier of the building management system by comparing a data point of the bin to the calculated target parameter and estimator of scale for the bin.

A controller for a building management system includes a first data interface configured to receive data from the building management system and a processing circuit including a processor and a memory device storing a fault detection rule having an initial threshold value. The processing circuit is configured to detect a first fault in the building management system using the stored fault detection rule having the initial threshold value and to use the data from the building management system to determine whether an adjustment to the stored fault detection rule is needed. In response to a determination that an adjustment to the stored fault detection rule is needed, the processing circuit is configured to calculate a new threshold value for the stored fault detection rule and update the stored fault detection rule by replacing the initial threshold value with the new threshold value.

A flexible control architecture for an electrical power microgrid provides resiliency when operating under varying threat levels. The architecture includes a microgrid control layer, an intermediate layer and a component control layer. A contingency level is computed based on conditions of the microgrid such as weather and system state. When the contingency level indicates a low degree of threat, the system operates in a centralized, top-down control configuration. When the contingency level indicates a high degree of threat, the system operates in a decentralized control configuration with the microgrid control layer performing only a monitoring function.
