Abstract

The invention discloses a robust optimization operation method for an elastic-guided distribution network after external interference, and belongs to the technical field of distribution network optimization operation. The present invention is based on the analysis of the distribution network model containing distributed energy in the island state under large-scale disturbances, and considers the restoration of the elastic index after the distribution network is disturbed, economy and environmental protection, and considers the normal operation of the power grid. Based on multiple constraints, a robust optimization strategy based on Benders decoupling is used to propose a solution method for the distribution network to minimize operating costs and total pollutant emissions. To sum up, the operation strategy proposed by the present invention and the optimal solution method for the disturbed distribution network can ensure the safe operation of the distribution network, and help to reduce the operation cost and the emission of pollutants.

Description

technical field

[0001] The invention relates to a robust optimization operation method of an elastic-guided distribution network after external interference, and belongs to the technical field of distribution network optimization operation. Background technique

[0002] The polar geophysical exploration ship is the main equipment used in the geophysical exploration stage of oil and gas resources, and it is also an important equipment in offshore oil development, which plays a vital role in offshore oil development. Due to the harsh environment and possible accidents in the polar regions, the threat to the distribution network cannot be ignored, and the massive access of various uncontrollable distributed energy sources also puts forward higher requirements for the safe operation of the distribution network. As an important hub connecting power users and transmission equipment, the distribution network's operating status will directly affect the quality of power consumption a...
