Abstract

The invention relates to an AC-DC series-parallel regional power grid spot market clearing calculation optimization method and device. The method comprises the steps of obtaining basic data; accordingto the basic data, establishing and solving an AC-DC series-parallel regional power grid spot market safety constraint unit combination model to obtain a safety constraint unit combination model calculation result; establishing and solving an AC-DC hybrid regional power grid spot market safety constraint economic dispatching model according to the basic data and the safety constraint unit combination model calculation result to obtain a safety constraint economic dispatching model calculation result; establishing and solving an AC-DC hybrid regional power grid spot market node marginal electricity price calculation model according to the basic data and the safety constraint economic dispatch model calculation result to obtain a node marginal electricity price, wherein the node marginal electricity price is used for resource allocation optimization. By the adoption of the method, spot market clearing calculation efficiency can be effectively improved, optimal resource allocation can beefficiently achieved, and time and labor are saved.

Description

technical field [0001] The present application relates to the technical field of power system information processing, and in particular to a method, device, computer equipment and storage medium for calculating and optimizing the clearing calculation and optimization of the AC / DC hybrid regional power grid spot market. Background technique [0002] At present, the construction of regional electricity market is an effective way to realize the optimal allocation of resources in a wider range, and an important carrier to restore the attributes of electricity commodities and promote the healthy development of the electricity industry. [0003] Among them, the eight spot pilot provinces in 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 inter-provincial tie lines is only considered as a boundary c...
