Assisted decision making method for load transfer in regional power grid

Abstract

The invention provides an assisted decision making method for load transfer in a regional power grid. The method comprises the following steps: (1) setting a target power-off device; (2) performing statistics on load information; (3) analyzing a load transfer strategy; and (4) evaluating economic safety. In the method, remote signalling, remote measuring and power grid topology information existing in a dispatching automation system are utilized fully to fastly and exactly generate a load transfer scheme capable of meeting the requirement of economic and safe operation of the power grid, thereby preventing the situations such as load shedding or long-time power off, out-of-limit overload and the like from happening during the load transfer scheme.

Description

Technical field [0001] The invention belongs to the field of electric power automation, and particularly relates to an auxiliary decision-making method for load transfer of a regional power grid. Background technique [0002] Regional power grids are generally closed-loop design, open-loop operation, connected through hot standby switches, and generally appear as radial in structure. Load transfer is a common problem in regional power grid operation and dispatch. When equipment is overloaded, equipment failure, power failure, equipment overhaul, in order to improve the reliability of power supply to users, dispatchers generally rely on dispatching experience or rough manual calculations , And then carry out load transfer and restore power supply to the lost load. Although the problem of power recovery for the lost load is solved by experience, whether the transfer path is optimal, whether the transfer operation is simple, and whether the operation mode after the transfer is econo...

AI Technical Summary

Problems solved by technology

Load transfer is a common problem in regional power grid operation scheduling. When encountering equipment overload, equipment failure, power outage, equipment maintenance, in order to improve the reliability of power supply to users, dispatchers generally rely on dispatching experience or rough manual calculations , and then carry out load transfer and restore power supply to the lost load. Although the problem of restoring power supply to the lost load has been solved by experience, whether the transfer path is optimal, whether the transfer operation is simple, and whether the operation mode after the transfer is economical Safety is uncertain. Generally, relevant information or records need to be queried before operation, and timeliness cannot be guaranteed. Especially in emergency situations, dispatchers often urgently need accurate and concise result information
