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

Abstract

The application discloses an electricity day-ahead market clearing calculation method, a system and an apparatus and a readable storage medium. According to the method, a first mathematical model is obtained by establishing a first objective function and a first constraint condition considering a depth peak regulation; the first mathematical model is utilized to obtain a first clearing result; a renewable energy unit abandoned electricity avoiding quotation quadratic curve, a thermal power unit energy quotation in the first mathematic model and a thermal power unit bid-winning output and depthpeak regulation amount in the first clearing result are utilized to establish a second objective function and a second constraint condition, and a second mathematical model is obtained; the second mathematical model is utilized to obtain a second clearing result; the second clearing result and the first clearing result are utilized to obtain the abandoned electricity avoiding amount and an abandoned electricity avoiding quotation of the renewable energy unit bid-winning; and finally, a comprehensive clearing result is obtained. According to the method, integrated clearing of the day-ahead market and the depth peak regulation is realized, and coordination and mutual arrangement among different energy sources are ensured.

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 ...
