Optimization method of power grid outage planning based on backtracking search and alternate iteration

Abstract

The power grid outage planning optimization method based on retrospective search and alternate iterations provided by the present invention includes: S1: inputting information such as power outage demand, power grid topology and load power prediction value; S2: obtaining power outage demand set; S3: setting outage plan set ;S4: Sort the power outage requirements; S5: Select a demand from the sorted power outage demand set for orchestration; S6: Determine the outage time of the current orchestration demand; S7: Extract the grid topology corresponding to the outage time of the current orchestration demand, And determine the adjustment plan that the current demand may have during the power outage time. If there is no way, return to S6, if there is, go to S9; S8: Backtracking operation and return to S5; S9: Update the corresponding grid topology during the power outage; S10 : Circulate S5-S9 to obtain the power outage time of all demands and the mode adjustment plan corresponding to demands. The invention can take into account the daily workload of the power grid in the scheduling period, and ensure the balance of the workload.

Description

technical field [0001] The invention belongs to the technical field of power grid control, and in particular relates to a power grid outage planning optimization method based on backtracking search and alternate iteration. Background technique [0002] Reasonable and scientific planning of power outages can reduce the number or time of equipment outages, thereby reducing the impact of equipment outages on the operation of the power grid. Existing automation systems are not yet able to support complex outage planning work, and most power grid companies still use manual scheduling to arrange outage plans. However, in manual scheduling, the professional technical ability and work experience of the personnel responsible for mode operation planning will directly affect the quality of the layout scheme; the dedicated personnel often independently complete the plan for the area in charge, and only rely on manpower to analyze the interaction between equipment power outage modes imp...

Problems solved by technology

[0004] Although some existing literature considers the three sub-problems of load transfer path optimization, coordinated maintenance optimization, and maintenance time optimization, the proposed model aims to minimize the load loss, and the proposed model is only suitable for low-voltage distribution networks. The resulting result may appear to be a loss of load
