Embodiment Construction

[0081] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0082] Example.

[0083] see Figure 1 to Figure 3 , in this embodiment, a method for analyzing key influencing parameters of electricity spot market clearing electricity price, comprising the following steps:

[0084] 1. Using the IEEE-39 node system for verification and analysis, the base state parameters of a power spot market are selected as follows: the operating cost coefficients of each unit in the entire network are all set as a=0.21, b=6.3, c=4.2, and the physical parameters of the unit are shown in Table 3 , the predicted load of the system is shown in Table 4, and the physical parameters of the line are shown in Table 5, and the positive and negative backup requirements are both 100MW. The benchmark val...

Abstract

The invention discloses an electric power spot market clearing electricity price key influence parameter analysis method, which comprises the steps of determining operation parameters influencing clearing electricity price according to an electric power spot market rule and a node electricity price model, and constructing an influence factor system comprising a unit cost class, a unit operation class, a system balance class and a section power flow class; then, further constructing an electric power spot market full-time clearing simulation model considering the carbon transaction cost, and determining an objective function and constraint conditions of the clearing model; and finally, on the basis of the power spot market clearing simulation model, the influence degree of each operation parameter on the market clearing electricity price is compared through a sensitivity analysis and correlation graph construction method, so that the key parameters influencing the power spot market are evaluated. According to the method, the operation parameters influencing the clearing electricity price in the electric power spot market are systematically sorted, and the influence degree of each parameter on the clearing electricity price can be simply and efficiently calculated and compared, so that the key parameters influencing the spot market are clear, and the decision-making efficiency of a market subject is improved.

Description

technical field [0001] The invention relates to the field of electric power spot market clearing, in particular to a method for analyzing key influencing parameters of electricity price clearing in the electric power spot market. Background technique [0002] The existing power spot market clearing model is a unit combination and economic dispatch model that integrates security constraints, and clearing power prices are closely related to factors such as grid parameters, unit parameters, and supply and demand parameters. Compared with medium and long-term transactions, spot electricity transactions deeply reflect the real electricity price in the dual dimensions of time and space. On the one hand, the real-time relationship between supply and demand has profoundly affected the spot price. When the power supply and demand in this period are unbalanced, the spot price may face strong fluctuation risks, which will pose certain challenges to the operation of the power system and...
