Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0036] The pricing method for grid power distribution provided by this application can be applied to determine the power distribution price for each node of the grid. Such as figure 1 Shown is a simple power grid network, where BUS1, BUS2 and BUS3 are three nodes of the power grid, and L1, L2 and L3 are three power grid lines connected through the above three nodes. The actual power grid in use has a large number of nodes and lines, and the connection relationship is complex. The pricing method for power grid distribution provided by this application can be applied to power distribution ...

Abstract

The invention relates to a power grid power distribution pricing method and device, computer equipment and a storage medium; the computer equipment calculates the maximum power flow data of a power grid line under the maximum power supply capacity of the power grid according to a pre-established maximum power supply capacity optimization model of the power grid, and calculates the power flow dataof the power grid according to a preset power flow equation; next, by taking the maximum power flow data as boundary conditions of line expansion, the extension time of each line of the power grid isobtained according to the power flow data; and the cost change value of each line before and after the power change of the node is calculated according to the extension time, and the marginal price ofeach node is calculated according to the cost change value. By the adoption of the method, the power grid cost can be apportioned according to the influence of the node load on the reliability cost of the power grid when power grid power distribution pricing is carried out, so that the power grid cost apportionment is more fair and reasonable, and fair competition of the electric power market isfacilitated.

Description

technical field [0001] The present invention relates to the technical field of power transmission and distribution pricing in the electric power industry, in particular to a pricing method, device, computer equipment and storage medium for power grid distribution based on the maximum power supply capacity of the power grid. Background technique [0002] At present, in practical application, my country's power distribution pricing mainly adopts the stamp method, in which each grid user shares the reliability cost of the grid. [0003] However, the above method does not reflect the impact of different users on the reliability cost of the power grid, which is unreasonable. Contents of the invention [0004] Based on this, it is necessary to address the above technical problems and provide a pricing method, device, computer equipment and storage medium for grid power distribution based on the grid's maximum power supply capacity. [0005] A pricing method for power grid distr...
