Embodiment Construction

[0078] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, a detailed description is provided in conjunction with preferred embodiments and accompanying drawings, as follows:

[0079] Such as figure 1 As shown, a power grid planning method based on carbon emissions and source-grid-load-storage interaction for the electricity spot market includes the following steps:

[0080] The first step is to obtain the historical data of the power grid: obtain the congestion Lagrangian multiplier (shadow parameter) of each line per hour in one year, the investment cost of upgrading energy storage, power supply, and transmission and distribution lines, and the existing power supply, energy storage , grid capacity and structure information, and load forecast information data for the next five years.

[0081] The second step is the analysis of grid congestion lines: according to the historical data of the gr...

Abstract

The invention relates to a power grid planning method oriented toelectric power spot market and based on carbon emission and source network load storage interaction. Compared with the prior art, the invention solves the defect that the power grid planning method cannot meet the actual use requirement. The method comprises the following steps: acquiring historical data of a power grid; analyzing a blocked line of the power grid; calculating power grid data before upgrading; constructing a power grid planning decision model; and solving the power grid planning decision model. According to the invention, a blocked line Lagrangian multiplier analysis method is adopted to analyze, sort and position blocking conditions in a power grid so as to determine addresses where a power transmission line needs to be upgraded and a power supply and energy storage need to be newly built or added, a planning decision-making target and a market simulation operation model are combined, and multiple indexes such as reliability, environmental protection and economy are combined, so that an optimal planning result is obtained.

Description

technical field [0001] The invention relates to the technical field of power grid planning, in particular to a power grid planning method based on carbon emissions and source-grid-load-storage interaction for the power spot market. Background technique [0002] my country's traditional power grid planning is based on the known power load forecasting scheme and power supply construction plan to meet the development of power transmission and demand, while ensuring the safety and reliability of power transmission, and minimizing the construction and operation costs of the power grid. In the planning mode of traditional power grid planning, power supply planning, transmission network planning, and distribution network planning are respectively carried out. Under the influence of multiple controllable factors, such as power generation price, power generation capacity, etc., the traditional power grid planning method can plan the optimal power grid structure under the background o...
