The invention relates to the technical field of power distribution network optimization, in particular to a power distribution network operation optimization method considering multiple uncertainties. According to the method, a
robust optimization framework considering multiple uncertainties and relevance of a
distributed power supply, a novel flexible load and distributed
energy storage is constructed, so that the limitation that modeling is dispersed and resource
coupling is ignored in a traditional method can be effectively overcome, random characteristics and association relationships of wind and light loads are accurately described by utilizing probability distribution and
Cholesky decomposition, and the robustness of the
distributed power supply, the novel flexible load and the distributed
energy storage is improved. And the flexibility of the
system is enhanced through
energy storage dynamic balance and flexible
load regulation and control, efficient solving is realized by adopting mixed integer
linear programming and a column-constraint generation
algorithm, and finally, on the premise of ensuring the
voltage safety of the power distribution network, the
power flow stability and the equipment capacity limitation, the
new energy consumption capability is remarkably improved, and the
system operation economy is optimized. And a scheduling scheme with high robustness and high implementability is generated.
