Abstract

The present application relates to a calculation and optimization method and device for clearing the spot market of an AC / DC hybrid regional power grid. The method includes: acquiring basic data; establishing and solving a safety-constrained unit combination model in the spot market of the AC / DC hybrid regional power grid according to the basic data, and obtaining a calculation result of the safety-constrained unit combination model; according to the basic data and the calculation result of the safety-constrained unit combination model , establish and solve the safety-constrained economic dispatch model for the spot market of the AC-DC hybrid regional power grid, and obtain the calculation results of the safety-constrained economic dispatch model; according to the basic data and the calculation results of the safety-constrained economic dispatch model, establish and solve the AC-DC hybrid regional power grid spot market. The node marginal electricity price calculation model is used to obtain the node marginal electricity price; the node marginal electricity price is used for resource allocation optimization. Using this method can not only effectively improve the calculation efficiency of spot market clearing, but also efficiently realize the optimal allocation of resources, saving time and effort.

Description

technical field

[0001] The present application relates to the technical field of power system information processing, and in particular, to a calculation and optimization method, device, computer equipment and storage medium for clearing the spot market of an AC / DC hybrid regional power grid. Background technique

[0002] At present, the construction of regional power market is an effective way to realize the optimal allocation of resources in a wider range, and it is an important carrier to restore the attributes of power commodities and promote the healthy development of the power industry.

[0003] Among them, the eight pilot provinces of my country have successively built a relatively complete provincial power spot market system and entered the stage of simulated trial operation. However, in the process of clearing the provincial spot market, the transmission power of the inter-provincial tie line is only considered as a boundary condition. It is not involved in the optim...
