Title:
METHOD AND SYSTEM FOR IDENTIFYING DOMINANT OVERVOLTAGE OF A HIGH-PROPORTION NEW ENERGY POWER SYSTEM, ELECTRONIC DEVICE, STORAGE MEDIUM, AND COMPUTER PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/207099
Kind Code:
A1
Abstract:
A method and system for identifying dominant overvoltage of a high-proportion new energy power system. The method comprises: respectively determining a new energy machine end voltage amplitude value and an alternating current bus voltage amplitude value (101); determining an overvoltage limit value ratio according to a ratio of the new energy machine end voltage amplitude value to the alternating current bus voltage amplitude value (102); determining a threshold overvoltage limit value ratio (103); respectively determining a maximum new energy machine end voltage value and a maximum alternating current bus voltage value that can be borne by a new energy machine end and an alternating current bus (104); and performing dominant voltage safety constraint identification according to the overvoltage limit value ratio, the threshold overvoltage limit value ratio, the maximum new energy machine end voltage value, and the maximum alternating current bus voltage value, and determining an identification result (105). According to the method, the overvoltage limit value ratio is used as an index, and powerful support can be provided for analysis and control of safety and stability of the high-proportion new energy power system.
