Electric power market clearing control method, device and system

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...

Problems solved by technology

[0004] However, the following defects still exist in the prior art: the generation cost of hydropower and thermal power differs greatly, the marginal cost of hydropower generation is relatively low, and the fixed cost is relatively high, while thermal power units are on the contrary, the fixed costs of thermal power units are relatively low, and The marginal cost of power generation is relatively high; if hydropower and thermal power compete in the same market, under the market model where the market margin is unified and cleared, it is easy to lead to market instability; and there may be free rides on low-priced hydropower, which will generally increase the cost of electricity on the user side The problem
