Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] figure 1 It is a flow chart of the method for calculating the shelved cost subsidy of coal-fired units based on the capacity market provided by the embodiment of the present invention, and the method includes:

[0037] S101, obtaining the CONE value and NE&AS value of the reference coal-fired unit and the old coal-fired unit respectively;

[0038] Among them, the value of CONE (Cost of New Entry) is the revenue obtained in the energy market, ancillary servi...

Abstract

The invention discloses a coal-fired unit shelving cost subsidy calculation method based on a capacity market. The method comprises the steps of acquiring CONE values and NE & AS values of a referencecoal-fired unit and an old coal-fired unit respectively; calculating the NCONE ratio, and the NCONE ratio is the ratio of the NCONE value of the old coal-fired unit to the NCONE value of the reference coal-fired unit; obtaining a capacity demand price curve, and obtaining a capacity clearing price according to the capacity demand price curve; and calculating the capacity subsidy price of the oldcoal-fired unit according to the capacity clearing price and the NCONE ratio. The invention discloses a coal-fired unit shelving cost subsidy calculation device based on a capacity market. By the adoption of the method, the survival problem of the old unit can be solved.

Description

technical field [0001] The invention relates to the field of electric power market, in particular to a calculation method for shelving cost subsidies of coal-fired units based on capacity market. Background technique [0002] In recent years, my country's power market reform has developed rapidly, and the dividends released by the market reform have enabled power users to enjoy more economical and affordable power services. In the market environment, some power generation companies are limited by their own power generation costs, and some power generation companies will have insufficient utilization hours of power generation or the on-grid electricity price is lower than the cost of power generation. The cost that the unit cannot recover under the environment of power market competition is called shelving cost. [0003] The problem of cost shelving of generator sets is particularly obvious in coal-fired enterprises. At present, in my country, there is no clear subsidy metho...
