Title:
METHOD FOR PATH SORTING IN LOAD TRANSFER DECISION-MAKING FOR OPEN-LOOP POWER GRID
Document Type and Number:
WIPO Patent Application WO/2022/052142
Kind Code:
A1
Abstract:
A method for path sorting in load transfer decision-making for an open-loop power grid. The method specifically comprises the following steps: step 1, determining a device that causes load transfer in an open-loop operating power grid; step 2, determining a power grid range within which a power cut occurs due to an exit or load shedding operation of a focus device, and denoting the power grid range as a target set [Q]; step 3, analyzing the target set [Q]; step 4, selecting a related power grid which is within a power grid range below a common root node device of a main standby side and the focus device; and step 5, exhausting transfer paths of the target set [Q] according to analysis results in steps 3 and 4, and sorting the transfer paths according to a priority principle. By constructing an intermediate power supply tree, the problems of an existing traditional power supply tree whereby same is too simple and cannot analyze paths, and of a method for analyzing and sorting paths by means of a wide-area topological power supply tree whereby same is too complex are solved.
