Abstract

The invention provides a task allocation method applicable to power distribution network topology analysis distributed computation. The task allocation method applicable to the power distribution network topology analysis distributed computation comprises simultaneously processing a plurality of topology analysis requests to form a task queue on the basis of distributed idle computer resources, decomposing large tasks into subtasks, distributing the subtasks to every computer for execution by means of an intelligence algorithm, combining all the subtasks after the topology is completed and obtaining a final result; formulating a task allocation algorithm and achieving quick topology analysis of a large-scale complex power distribution network with least cost time during a distributed computing process as the target and PSO (Particle Swarm Optimization) as means.

Description

technical field [0001] The invention relates to a task allocation method, in particular to a task allocation method for distribution network topology analysis distributed calculation. Background technique [0002] Classical scientific research on power distribution systems generally uses IEEE calculation examples as the experimental object, and engineering applications usually use a single feeder as the basic processing unit; these processing objects are relatively simple, and the topology analysis calculation is small in scale and consumes less time. Some network models can even Using a pure matrix model description, it can be directly used in mathematical calculations, and topology analysis is not required when the network structure remains unchanged. A large number of equipment in a large and complex distribution network makes the network structure more likely to change, and the frequency of topology analysis is increased. Complex objects and massive data make topology an...
