Electric power spot market clearing method, system and device considering peak regulation and medium

Abstract

The invention belongs to the field of electric power system automation, and discloses an electric power spot market clearing method, system and device considering peak regulation and a medium, and themethod comprises the steps: obtaining a network model of an electric power system and an adjustment electric quantity needed by the electric power system; obtaining operation information and quotation information of each unit in the power system; wherein the quotation information comprises real-time balance adjustment quotation information and peak regulation auxiliary service quotation information; based on the network model of the electric power system, clearing the electric power spot market of the electric power system according to the adjustment electric quantity and the operation information and quotation information of each unit under a preset electric power system safety constraint condition by taking the minimization of the adjustment cost as an optimization target to obtain an adjustment plan of each unit in the electric power system; and adjusting each unit in the power system according to the adjusting plan. Minimization of power system adjustment cost and optimization ofunit adjustment scheduling are effectively realized, the making difficulty of an adjustment plan is reduced, and reasonable and effective adjustment of each unit is realized.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and relates to a method, system, equipment and medium for clearing an electric power spot market considering peak regulation. Background technique [0002] With the rapid development of clean energy and the gradual increase in the proportion of direct transactions, the uncertainty of clean energy power generation and the contradiction between the rigid execution of direct transaction contracts have become increasingly prominent. The future safe and economic operation of power grids will face many problems, and a complete market mechanism system needs to be established to deal with the problems faced. [0003] In recent years, the real-time balance adjustment mechanism adopted in the electricity spot market has played an important role in solving the imbalance between supply and demand caused by ultra-short-term load forecasting. Moreover, with the establishment of the peak-shaving...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned existing technology, when adjusting the unbalanced power of the power system, all units in the power system cannot be uniformly adjusted, the minimization of adjustment costs and the optimization of unit adjustment and scheduling cannot be realized, and the adjustment plan is complicated. , the shortcomings of being unable to make reasonable and effective adjustments to each unit participating in the power spot market, providing a method, system, equipment and medium for clearing the power spot market that considers peak regulation
