  • Publication number: 20250125630
    Abstract: A method of operating a microgrid system includes: obtaining a microgrid dispatch schedule input that includes a schedule of required electrical energy generation for the microgrid system for a given time period; filtering the scheduled dispatch input and converting the scheduled dispatch input into power levels to meet power demands for required electrical energy generation of the dispatch schedule input for the microgrid system; receiving a current load level for the microgrid system based on one or more electrical loads electrically coupled to the microgrid system; comparing the schedule of required electrical energy generation to an actual required electrical energy generation for the microgrid system; and dispatching one or more electrical assets in real time to meet a difference between the scheduled required electrical energy generation and the actual required electrical energy generation.

  • Publication number: 20250070595
    Abstract: A method of configuring a microgrid including: receiving configuration inputs from an operator, the configuration inputs including an intended bus structure, a plurality of energy resources data, and energy resources priorities; classifying assets and asset groups based on the plurality of energy resources data; and generating a microgrid configuration based on the one or more configuration inputs, the microgrid configuration providing for automatic operation of the microgrid.

  • Publication number: 20240088668
    Abstract: Systems and methods are disclosed for controlling distributed energy resources. Controllers in a peer-to-peer network are configured to act as a dispatch handler for electrical buses connected to respective set of power assets and loads. The controllers are configured to broadcast micro-grid configuration information over the peer-to-peer network to each controller. Each controller is configured to determine a segmentation of the electrical buses into isolated micro-grids; and assign a controller as a supervisor for each of the isolated micro-grids. The controllers are configured such that supervisor controller assigned to isolated micro-grid is configured to determine dispatch commands for power assets associated with the isolated micro-grid to handle load requirements and broadcast the determined dispatch commands over the peer-to-peer network.

  • Patent number: 11725555
    Abstract: An aftertreatment system for a diesel engine may include a diesel particulate filter configured for placement in fluid communication with the diesel engine to receive an exhaust flow. The system may also include a selective catalytic reduction system configured for arrangement downstream of the diesel particulate filter and a NOx sensor configured to measure a NOx concentration in the exhaust flow entering the selective catalytic reduction system. The system may also include a controller configured to estimate a ratio of NO2 to NOx downstream of the diesel particulate filter and based on a factor affecting the generation of NO2 upstream of the selective catalytic reduction system. The controller may also be configured to adjust the measured NOx concentration based on the ratio to provide an estimated actual NOx concentration and dose diesel exhaust fuel into the exhaust flow based on the estimated actual NOx concentration.
