Embodiment Construction

[0024] Such as figure 1 As shown, in one embodiment, a method for optimizing a power transmission cost allocation design scheme includes the following steps:

[0025] In step S100, information of a preset area is acquired, and the information includes tie lines in the preset area, lengths of the tie lines, nodes connected to the tie lines, and basic power of the nodes.

[0026] The preset area can be different areas such as various regions, provinces, and cities. The tie line refers to a special wire that acts as a connection between the power plant and the grid, that is to say, through it, the electric energy generated by the power plant can be transmitted to the grid. , can also transmit the electric energy on the grid back to the power plant, and the tie line can connect two power systems, two inter-provincial power grids, two substations, or even two distribution stations, giving full play to the power generation and supply capabilities of both parties and promoting Optim...

Abstract

The invention relates an optimization method and system for a design scheme of transmission cost allocation. The method comprises the following steps: firstly, obtaining preset area information which comprises tie lines in a preset area, the line lengths of the tie lines, nodes connected with the tie lines and basic power of the nodes, calculating to obtain marginal megawatt kilometers of the nodes based on the methods of GGDF(Generalized Generation Distribution Factor) and GLDF(Generalized Load Distribution Factor), and then calculating the initial allocation cost of the nodes according to the marginal megawatt kilometers of the nodes to obtain the design scheme of the transmission cost allocation, when the initial allocation cost cannot meet a preset income ratio, modifying the initial allocation cost through a preset modified constant to optimize the design scheme of the transmission cost allocation. The obtained optimized design scheme of the transmission cost allocation can ensure reasonable returns of grid companies, effectively promote the market competition and development, push reasonable planning and construction of a power grid, and provide a good guide for the coordinated development of power supply construction and power grid construction.

Description

technical field [0001] The invention relates to the field of power grid transmission cost allocation, in particular to an optimization method and system for a power transmission cost allocation design scheme. Background technique [0002] Power transmission service is the process of delivering electric energy to consumers in a safe, economical and high-quality manner. It is the bridge connecting power generation and power consumption, and the only carrier of power trading. A reasonable transmission fee will provide market members with correct economic signals and promote the optimal use of transmission resources. At the same time, the transmission link will in turn have certain constraints and influences on power generation and users. Participation in which user markets compete has a great influence, so the allocation of transmission costs is a key issue in the electricity market. [0003] Transmission cost plays an important role in the reliable and stable operation of the...
