Headquarter and subdivision integrated multi-stage scheduling optimization method

Abstract

The invention discloses a headquarter and branch integration multi-level scheduling optimization method. The method comprises the steps: Step 1, making basic data preparations, wherein the basic datapreparation comprises national dispatching preparation, branch dispatching preparation and provincial dispatching preparation; Step 2, respectively compiling respective constraint and boundary conditions for countries, divisions and provinces; Step 3, performing overall calculation on the national dispatch plan on the panoramic information by the national dispatch; Step 4, performing iterative adjustment between the national dispatch and the provincial dispatch to realize multi-stage dispatch optimization; And step 5, performing result display and return: returning the calculated headquartersand subdivisions integrated multi-level scheduling optimization result to the national, subdivisional and provincial scheduling institutions. According to the method, repeated iteration of a scheduling plan compiled in a current national, provincial and provincial serial iteration mode is reduced, and the capability of coordinated scheduling among national, provincial and multi-level scheduling and the resource overall optimization effect are enhanced.

Description

technical field [0001] The invention belongs to the technical field of electric power system operation dispatching, and in particular relates to a dispatching optimization method of a multi-level dispatching organization based on the integration of headquarters and divisions. Background technique [0002] At present, my country has established a national, branch, and provincial three-level dispatching planning workflow, realizing the coordinated preparation of multi-level dispatching plans. However, the rapid development of UHV has made AC-DC coupling, sending and receiving terminal coupling, and high-voltage and low-voltage coupling closer in the power grid, which poses new challenges to the existing dispatch planning business model of provincial balance and weak coupling of dispatch at all levels. At present, the national sub-provincial dispatching plan business adopts the method of serial work between the upper and lower levels. After the national dispatch plan is complet...

AI Technical Summary

Problems solved by technology

At present, the reciprocating coordination cycle of the serial preparation plan between the dispatching departments of the country, branch and province is long, and the interaction between levels is too frequent. The complexity of the process, the pressure of data transmission, and the intensity of personnel work are all increasing. The degree of overall optimization needs to be improved
