Regional electricity market clearing method and device and storage medium

Abstract

The invention discloses a regional electricity market clearing method and device and a storage medium. The method comprises the steps: building an inter-province power transmission and reception planoptimization model, solving the inter-province power transmission and reception plan optimization model, and obtaining an inter-province power transmission and reception plan; establishing a trans-provincial power market clearing model according to the inter-provincial power transmission and reception plan, and solving the trans-provincial power market clearing model to obtain a trans-provincial power market clearing result; establishing an inter-provincial tie line power plan optimization model according to the inter-provincial power transmission and reception plan, and solving the inter-provincial tie line power plan optimization model to obtain an inter-provincial tie line power plan; according to the inter-province tie line power plan, establishing an in-province power market clearingmodel and solving to obtain an in-province power market clearing result; and carrying out regional power dispatching according to the trans-provincial power market clearing result and the intra-provincial power market clearing result. According to the method, the establishment of a transitional two-stage regional power market is facilitated, the inter-province power barrier is eliminated, and thereasonable dispatching of regional power is better realized.

Description

technical field [0001] The invention relates to the technical field of power system operation scheduling, in particular to a clearing method, device and storage medium for a regional power market. Background technique [0002] At present, my country's regional power market still has uneven distribution and unbalanced output in terms of power dispatching. On the one hand, it is impossible for my country's power market to be positioned in the national power market in a long historical period. This is because the capacity of my country's transmission network It is still far from the transmission network capacity required by the national electricity market; Various types of adjustments between major provinces and power-consuming provinces, and between major hydropower provinces and thermal power provinces are necessary, that is, inter-provincial power barriers must be broken. Therefore, the establishment of regional power markets is almost the only reasonable solution in my countr...
