Electricity day-ahead market clearing calculation method, system, device and readable storage medium

Abstract

This application discloses a calculation method, system, device, and computer-readable storage medium for calculating the clearing of the power day-ahead market. This application obtains the first mathematical model by establishing the first objective function and the first constraint conditions that consider deep peak regulation, and uses The first mathematical model obtains the first clearing result, using renewable energy units to avoid the quadratic curve of curtailment quotation, the energy quotation of thermal power units in the first mathematical model, and the standard output and deep peak regulation of thermal power units in the first clearing result The second objective function and the second constraint conditions are respectively established to obtain the second mathematical model, the second clearing result is obtained by using the second mathematical model, and the winning bid of the renewable energy unit is obtained by using the second clearing result and the first clearing result Avoid electricity curtailment and avoid electricity curtailment quotes, and finally get a comprehensive clearing result, realize the integrated clearing of the day-ahead market and deep peak shaving, and ensure the coordination and interaction between different energy sources.

Description

technical field [0001] The present invention relates to the technical field of electric power dispatching automation, in particular to a method, system, device and computer-readable storage medium for calculating the day-ahead electric power market clearing. Background technique [0002] In recent years, with the continuous growth of my country's renewable energy installed capacity, due to the lack of flexible peak-shaving resources, my country is facing a serious dilemma of abandoning wind and light; Peak potential to alleviate the plight of wind power consumption. The Northeast region first piloted the power peak-shaving auxiliary service market in October 2014. Since the establishment of the market, it has operated well. In the heating seasons of 2014 and 2015, a total of 10.994 billion kilowatts of peak-shaving space was tapped. However, the market operates as an independent market without a spot market. With the advancement of the power market reform, the construction of ...

Problems solved by technology

[0003] However, due to our country's resource endowment, in the construction of the power day-ahead market, our country will still face the problem of a serious shortage of system peak-shaving resources. How to realize the coordination and mutual placement of different energy sources is an important issue that must be considered in the construction of my country's day-ahead market
