  • Method for management and optimization of hydropower generation and consumption
    Patent number: 10516265
    Abstract: An optimization and management system using a global linearization approach and mixed integer linear programming to perform the dispatch and to schedule a river system for ten days forward while subject to real world, hourly physical, biological, environmental, and recreational constraints. The optimizer system uses a combination of slack variables and stitching methods to approximate a highly nonlinear optimization problem, thereby generating realtime generation schedules to promote to the management authority.
    Type: Grant
    Filed: October 2, 2017
    Date of Patent: December 24, 2019
    Assignee: The Energy Authority, Inc.
    Inventors: Zengjian Hu, John Putz, Sean J. Mackey, Yuen Y. Chan, Yohan Sutjandra, Jonah C. Tsui
