Patent number: 11916382Abstract: A system may determine configuration information associated with a power system for a work site that includes one or more power sources. The system may determine respective operation parameters of the one or more power sources and one or more performance criteria associated with the power system. The system may determine a baseline operation plan for the power system. The system may identify an optimization analysis technique and may process, using the optimization analysis technique, the configuration information associated with the power system, the respective operation parameters of the one or more power sources, and the one or more performance criteria associated with the power system to generate the optimized operation plan for the power system. The system may cause, based on the baseline operation plan for the power system and the optimized operation plan for the power system, one or more actions to be performed.Type: GrantFiled: November 19, 2021Date of Patent: February 27, 2024Assignee: Caterpillar Inc.Inventors: Yanchai Zhang, Syed Ameenuddin Hussain, Baoyang Deng, Zhijun Cai, Shiferaw D. Beyene, Casey Alan Otten, Perry Converse, Theodore E. Wiersema, Michael A. Snopko

Patent number: 11541763Abstract: A control system implementing a hybrid energy storage system (ESS) optimization strategy is disclosed. The hybrid ESS optimization strategy may be implemented in a machine that comprises a power system that includes a plurality of power sources and a power controller that includes one or more processors. The power controller may receive information related to a set of brake-specific fuel consumption (BSFC) maps associated with the plurality of power sources, determine a performance indicator using a cost function associated with the plurality of power sources, and generate a command to operate the power system based on a power distribution that minimizes an energy cost to operate the power system based on the information related to the set of BSFC maps, the performance indicator, and a load associated with the power system.Type: GrantFiled: February 11, 2020Date of Patent: January 3, 2023Assignee: Caterpillar Inc.Inventors: Yanchai Zhang, Baoyang Deng, Michael A. Snopko, Theodore E. Wiersema

Patent number: 9988135Abstract: A system for limiting power to a plurality of on-line consumers includes an operating characteristic sensor associated with each of a plurality of prime movers and a controller. The controller is configured to determine a maximum torque capability of each of the plurality of prime movers, determine the available electrical power response of each of the plurality of generators, determine a total available electrical power response, and determine a total maximum power demand. The controller then compares the total available electrical power response to the total maximum power demand, and upon the total maximum power demand exceeding the total available electrical power response, limits power to the plurality of on-line consumers to no more than the total available electrical power response.Type: GrantFiled: March 31, 2016Date of Patent: June 5, 2018Assignee: Caterpillar Inc.Inventors: Perry D. Converse, Theodore E. Wiersema

Publication number: 20150274275Abstract: A power system is provided for a marine or petroleum drilling vessel. The power system may have a plurality of power sources, at least one power consumer, and an input device configured to generate a signal indicative of a desired output. The power system may also have a load manager associated with the at least one power consumer and configured to create a power demand for the plurality of power sources based on the signal and an actual output, and a controller. The controller may be configured to determine a plurality of performance goals for the plurality of power sources, determine a priority of the performance goals, retrieve from the plurality of power sources at least one performance map corresponding with each performance goal, and selectively apportion the power demand between of each of the plurality of power sources based on the at least one performance map and based on the determined priority.Type: ApplicationFiled: March 27, 2014Publication date: October 1, 2015Applicant: CATERPILLAR INC.Inventors: Maurice J. DUST, Theodore E. WIERSEMA, III, Perry D. CONVERSE, Eric W. OHLSON
