Power system spinning reserve auxiliary service transaction method

Abstract

The invention provides a power system spinning reserve auxiliary service transaction method, and belongs to the field of power marketization transaction. The method includes: starting market transaction when the power generation power of the whole network reaches 90% or above of the maximum power generation power of the whole network on that day and the spinning reserve capacity of the whole network thermal power generating unit is lower than 15% of the whole network thermal power starting capacity; taking 15 minutes as a period, dividing the thermal power plants into a seller power plant anda buyer power plant by calculating the maximum capacity load rate of each thermal power plant, and respectively calculating the standby power consumption of the seller power plant and the standby vacancy power of the buyer power plant; and according to different settlement conditions, respectively obtaining the seller power plant and income and the buyer power plant cost in each statistical period. Excitation compatibility can be realized, unified management of spinning reserve is realized, and the enthusiasm of a thermal power enterprise for providing spinning reserve for a power grid is fully aroused.

Description

technical field [0001] The invention relates to the field of electric power market-oriented transactions, in particular to a method for transaction of an auxiliary service for a power system spinning reserve. Background technique [0002] In recent years, my country's power industry, especially clean energy, has developed rapidly. Major changes have taken place in the structure of power sources and grid structures. The scale of the system has continued to expand. The complexity of system operation and management has also increased greatly, and higher requirements have been put forward for the safe and stable operation of the system. At present, problems such as abandonment of wind, abandonment of solar energy, abandonment of water, nuclear restrictions and system peak regulation, and contradictions between electricity and heat in the heating season are prominent in some areas of our country. Some of the current compensation methods for electric power auxiliary services have b...

Problems solved by technology

[0004] 1. When the power balance of the power grid is tense, due to the obstruction of the output of peak thermal power units, the spinning reserve capacity of the power grid is insufficient, threatening the safety of power supply of the power grid;

[0005] 2. When the power balance of the power grid is surplus, because the output of peak thermal power units is hindered, in order to meet the needs of power balance, the dispatching department will be forced to increase the capacity of thermal power start-up, resulting in a decrease in the downward adjustment ability of the power grid in low valleys, and affecting the acceptance level of wind power in low valleys
