Emergency resource optimal configuration method suitable for power system recovery

Abstract

The invention discloses an emergency resource optimal configuration method suitable for power system recovery. The method is characterized in thaton the basis of considering investment cost of an emergency power supply vehicle, power failure loss cost of a transformer substation, operation and maintenance cost of an emergency power supply and power transmission cost under the constraint of a traffic network, calculating the spectral importance, the load capacity importance and the load importance of a node of the power system, and evaluating power failure retrieval loss of the node and establishing optimal configuration of an emergency power supply vehicle, and finally performing iterative computation by using a discrete binary particle swarm algorithm to obtain the optimal configuration location of the emergency power supply vehicle and an optimal route for power system recovery. The method is advantaged in that on the basis of comprehensively considering factors such as manufacturingcost of the emergency power supply vehicle, the maximum loss of configuration retrieval of the emergency power supply vehicle is used as a target function, and a discrete binary particle swarm algorithm is used for obtaining an emergency power supply vehicle configuration sequence. The method is scientific and reasonable, and economic loss caused by blackout can be reduced to the maximum extent.

Description

technical field [0001] The invention relates to a method for configuring emergency resources for power system recovery, and belongs to the technical field of power transmission and distribution. Background technique [0002] With the rapid development of social economy and the continuous improvement of informatization and modernization, people rely more and more on electricity. Once a major power outage occurs in the power system, it will not only affect people's normal life order, but may also cause major economic losses or personal casualties. Modern power systems are equipped with a large number of advanced safety automatic devices and protection equipment. Blackout itself is a small probability event, but it has occurred frequently in recent years. On August 14, 2003, large-scale power outages occurred in the Midwest, Northeast of the United States, and Ontario, Canada; on November 4, 2006, the most serious power outage in recent decades occurred in nearly eight Europea...

Problems solved by technology

The emergency power supply vehicle has strong mobility and environmental adaptability, is not affected by geographical location and environment, and can respond immediately to catastrophic accidents. It is a generator set independent of normal power supply, but its cost, operation and maintenance costs High, and affected by traffic network connectivity and congestion, it is necessary to comprehensively consider technology, economy and traffic conditions to optimize the allocation of emergency power vehicles
