Problems solved by technology

However, due to China's resource endowment, coal-fired thermal power units cannot be started and stopped frequently during the clearing of the electric energy market, so it is still unable to solve the problem of a serious shortage of system peak-shaving resources

Abstract

The invention discloses a hydropower consumption method and device based on deep peak regulation of thermal power. The method includes the steps of: obtaining an electric energy market report, establishing a pre-clearing model of the electric power market without considering deep peak regulation of thermal power, and solving it to obtain a pre-clearance model. Result: According to the pre-clearing results, the electricity quantity of abandoned water in each hydropower plant is obtained; it is judged whether there is abandoned water in each hydropower plant, if there is no abandoned water, the pre-clearing results are used as the final clearing results; if there is For abandoning water, it is necessary to analyze the abandoned water to determine the demand for deep peak regulation of thermal power; obtain the market report for deep peak regulation of thermal power, establish a joint clearing model of the power market that considers deep peak shaving of thermal power, and solve it to obtain the joint clearing result; The combined clearing results are used to adjust hydropower consumption. The present invention performs deep peak regulation in the case of water abandonment in the power system, so that the thermal power unit voluntarily lowers its output, frees up more power generation space for hydropower, and reduces water abandonment.

Description

technical field [0001] The invention relates to the technical field of power system operation regulation, in particular to a hydropower consumption method and device based on deep peak regulation of thermal power. Background technique [0002] The electricity market provides the driving force and platform for the full consumption of renewable energy and the efficient operation of the Energy Internet. Foreign mature power markets mainly solve the problem of system peak regulation through the spot market. However, due to China's resource endowment, coal-fired thermal power units cannot be started and stopped frequently during the clearing of the electric energy market, so it is still unable to solve the problem of serious shortage of system peaking resources. [0003] Usually in the electricity market mode, thermal power units need to declare their minimum economic output. The schedulable space of the unit in the electric energy market is the range from its minimum output to...
