Abstract

The invention provides a power distribution-gas network distributed collaborative programming method and system considering influences of a power transmission network. The method comprises the following steps: obtaining typical operation scenes of power distribution-gas networks; according to the obtained typical operation scenes and a preset power distribution-gas network distributed collaborative programming model, obtaining an optimal distributed collaborative programming scheme of the power distribution-gas networks, wherein the power distribution-gas network distributed collaborative programming model comprises a power transmission network sub-problem mixed integer quadratic programming model, a power distribution network sub-problem mixed integer quadratic programming model and a gas distribution network sub-problem mixed integer quadratic programming model; and sequentially carrying out distributed iterative solution on the three mixed integer quadratic programming models by utilizing an analytical target cascading algorithm. According to the invention, by establishing the mixed integer quadratic programming models of power transmission networks, power distribution networks and gas distribution networks, a distributed solving process based on the analytical target cascading algorithm is constructed, and distributed collaborative programming of multiple power distribution-gas networks is realized.

Description

technical field [0001] The disclosure belongs to the technical field of electric-gas coupling network extension planning, and specifically relates to a method and system for distributed collaborative planning of power distribution-gas network considering the influence of transmission network. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In recent years, with the gradual emergence of traditional energy pollution problems and the increasing pressure of energy conservation and emission reduction, it has become an irresistible trend to vigorously develop renewable energy power generation technology and replace traditional power generation methods. The increase in the penetration rate of distributed renewable energy generation in the distribution network not only gave birth to the development of power to gas (P2G) technology, increased the ...
