Hydroelectric coupling market clearing method, system and device and readable storage medium

Abstract

The invention belongs to the field of electricity markets, and discloses a hydroelectric coupling market clearing method, system and device and a readable storage medium, and the market clearing method comprises: obtaining the operation boundary condition, market declaration information and water regimen information of a power grid; establishing a unit operation constraint, a system balance constraint and a network constraint of the power grid according to the operation boundary condition and the market declaration information based on the future state network topology model of the power grid; establishing power generation and water consumption constraints according to the water regimen information, and establishing power generation capacity constraints according to the power generation and water consumption constraints and the market declaration information; and based on the future state network topology model of the power grid and the market declaration information, by taking power generation cost minimization as an optimization target, carrying out market clearing calculation to obtain a clearing result under the conditions of meeting unit operation constraints, system balance constraints, network constraints and power generation capacity constraints. Clearing calculation of a power grid containing cascade hydropower is realized, and technical support is provided for deepening reform of a power market.

Description

technical field [0001] The invention belongs to the field of electric power market, and relates to a hydroelectric coupling market clearing method, system, equipment and readable storage medium. Background technique [0002] With the advancement of electricity market reform, many provinces in China have initially established medium and long-term trading markets, and the construction of provincial-level electricity spot markets has also continued to advance. As the second largest conventional energy source, hydropower occupies an extremely important position in the power system structure. In actual operation, hydropower has a high proportion of installed capacity, large differences in power generation principles between peak and dry seasons, complex grid structures with many constraints, and complex cascade relationship coupling in watersheds. The large difference in the competitiveness of market players has brought huge challenges to the construction of the Sichuan electric ...
