Frequency modulation market quotation method based on comprehensive frequency modulation performance index and credibility index

Abstract

The invention discloses a frequency modulation market quotation method based on a comprehensive frequency modulation performance index and a credibility index. The method comprises the following steps: analyzing the comprehensive frequency modulation performance index and the credibility index of a frequency modulation market subject; a comprehensive frequency modulation performance index and a credibility index are introduced into market scheduling quotation information management; establishing a frequency modulation market clearing model containing a comprehensive frequency modulation performance index and a credibility index; and for the model, setting the constraint conditions of the system and the frequency modulation main body, taking the lowest auxiliary service purchased by the power grid dispatching side as the target, thereby exciting each market main body to provide high-quality frequency modulation resources, and saving the frequency modulation cost of the power grid. Analysis is performed by integrating the frequency modulation performance index and the credibility index, the clearing model including the wind power participation frequency modulation market is established, the real capacity of the frequency modulation resource provided by the frequency modulation subject is measured, the quality of the frequency modulation resource is improved, and the auxiliary service cost of the power grid is saved.

Description

technical field [0001] The invention relates to the technical field of frequency regulation markets, in particular to a frequency regulation market quotation method based on comprehensive frequency regulation performance indicators and reliability indicators. Background technique [0002] With the increase in the installed capacity of domestic renewable energy in recent years, we have to consider the impact of the power fluctuation and randomness of renewable energy on the distribution network, making most green and clean energy the "load" of the distribution network . At present, most of the domestic frequency regulation auxiliary services provided are conventional energy units. With the implementation of the domestic "dual carbon" policy, the installed capacity of domestic thermal power plants will not increase significantly. At that time, conventional energy units cannot provide sufficient auxiliary services. It is an inevitable trend for renewable energy units to provid...

Problems solved by technology

At present, most of the domestic frequency modulation auxiliary services are conventional energy units. With the implementation of the domestic "double carbon" policy, the capacity of domestic thermal power assembly units will not increase significantly. At that time, conventional energy units will not be able to provide sufficient auxiliary services. It is an inevitable trend for renewable energy units to provide auxiliary services

The state encourages new energy units to participate in system frequency regulation. Due to the large fluctuations in the output of new energy units, according to the existing quotation method of frequency regulation entities, it cannot reflect the real capacity of frequency regulation resources provided by frequency regulation entities, nor can it measure the quality of frequency regulation resources.
