Abstract

The invention discloses a water and electricity absorption method and device based on thermal power deep peak regulation. The method comprises the steps: obtaining an electric energy market declaration, building an electric power market pre-clearing model which does not consider the thermal power deep peak regulation, carrying out solving, and obtaining a pre-clearing result; obtaining a water abandoning electric quantity condition of each hydraulic power plant according to the pre-clearing result; judging whether water abandoning exists in each hydraulic power plant or not, and if not, takingthe pre-clearing result as a final clearing result; if water abandoning exists, carrying out water abandoning analysis, and determining a thermal power deep peak regulation quantity demand; obtainingthermal power deep peak regulation market declaration, establishing an electric power market joint clearing model considering thermal power deep peak regulation, and carrying out solving to obtain ajoint clearing result; and carrying out water and electricity absorption adjustment according to the joint clearing result. Deep peak regulation is performed under a condition that water is abandonedin a power system so that a thermal power generating unit voluntarily reduces output, more power generation spaces are vacated for water and electricity, and abandoned water is reduced.

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...
