摘要：
The power outage scenario, restoration process and load functions under emergency situations may affect the power supply restoration urgency of load during distribution network restoration. Usually, the importance level or degree of the object to be restored is statically set according to its own restoration value, which restricts the refined management of limited restoration resources. Considering the impact of cold load pick-up characteristic and functional coupling relationship among loads on load unit restoration value, considering the impact of controllability of intermittent power output on generation restoration value, combining with the potential restoration value provided by bus restoration to other surrounding objects to be restored, together with the sufficiency of system, the cost of restoration and the uncertainty of restoration operations, a dynamic evaluation approach for load and generator importance degree is proposed with comprehensive restoration benefits, costs and risks. Based on this, a multi-process optimization model for power supply restoration of the distribution network and a partition parallel restoration decision-making method are developed. Finally, simulative results verify that the proposed strategy can effectively improve the utilization of resources. © 2021 Electric Power Automation Equipment Editorial Department.
