specific Embodiment 1

[0025] The embodiment of the present invention firstly describes a method for market clearing control of electric power. figure 1 A flow chart of an embodiment of a method for market clearing control of electric power according to the present invention is shown. like figure 1 As shown, the method includes the following steps:

[0026] S1: Obtain the declared price data set and the water and electricity clearing data set.

[0027] Due to the low marginal cost of hydropower generation, if hydropower and thermal power (or other types of power generation) are placed in the same competition, the market is likely to be unbalanced and the cost of the user side will be raised. In this regard, it is necessary to properly adjust the settlement price of hydropower through a series of calculations based on the declared benchmark price of hydropower in spot market bidding set by the government and the self-declared price of hydropower suppliers, so as to avoid the unbalanced competition ...

specific Embodiment 2

[0092] In addition to the above method, the embodiment of the present invention also describes a market clearing control device for electricity. figure 2 A structural diagram of an embodiment of a market clearing control device for electric power according to the present invention is shown.

[0093] like figure 2 As shown, the market clearing control device includes a data acquisition unit 11 , a price calculation unit 12 and a clearing control unit 13 .

[0094] The data acquisition unit 11 is used to acquire the declared price data set and the water and electricity clearing data set. The declared price data set includes a government benchmark price data set, a self-declared thermal power price data set, and a self-declared hydropower price data set.

[0095] The price calculation unit 12 is used to use the preset hydropower market clearing model, the preset formula for calculating the price difference of hydropower in operation, the constraint condition group, the govern...

specific Embodiment 3

[0102] In addition to the above method and device, the present invention also describes a market clearing control system for electricity. image 3 A structural diagram of an embodiment of an electric market clearing control system according to the present invention is shown.

[0103] like image 3 As shown, the market clearing control system includes a clearing control module 1, a data management module 2, and a user interaction module 3, and the clearing control module 1, the data management module 2, and the user interaction module 3 are connected to each other by communication.

[0104] Among them, the clearing control module 1 is used to implement the market clearing control method of electric power as mentioned above, and the data management module 2 is used to store the declared price data group, the water and electricity clearing data group and the data generated during the implementation of the market clearing control method. data; the user interaction module 3 is use...

Abstract

The invention discloses a power market clearing control method, device and system. The device comprises a data acquisition unit, a price calculation unit and a clearing control unit. The system comprises a clearing control module, a data management module and a user interaction module. Modeling is carried out according to a preset hydropower market clearing model set, the government standard price data set, the self-declaration hydropower price data set, the self-declaration thermal power price data set and the hydropower clearing data set, and an economic optimal solution of the model set is obtained through a preset constraint condition set; then, the settlement price of the water and electricity in transportation is calculated through the preset price difference settlement formula, clearing control is carried out on the electricity market according to the settlement price of the water and electricity in transportation and the preset market control method, and the market clearing control method, device and system improve the market stability on the premise of bidding the hydropower and thermal power on the same platform in the electricity.

Description

technical field [0001] The invention relates to the field of market clearing control of electric power, and relates to a method, device and system for market clearing control of electric power. Background technique [0002] At this stage, my country is in the primary stage of power market reform, and most markets have only carried out market-oriented transactions of thermal power units for the time being, while hydropower units have not been allowed to enter the power market. However, with the deepening of electricity market reform, the power generation plan of various types of power sources will also be gradually liberalized, facing the problem of clearing and pricing mechanisms for hydropower and thermal power to compete in the same market. [0003] In the prior art, regulation of market transactions is usually realized by adjusting the price of electricity, so as to realize market clearing. [0004] However, the following defects still exist in the prior art: the generat...
