Carbon capture virtual power plant scheduling optimization method

Abstract

The invention discloses a carbon capture virtual plant scheduling optimization method, comprising the steps of S1, constructing a dual carbon amount model of a carbon capture unit for a thermal power plant, the dual carbon amount module being used for representing an absorption link and a regeneration link of a liquid storage type carbon capture unit in a decoupling manner; S2, constructing a virtual power plant aggregated with the thermal power plant and a clean energy power plant, and determining a scheduling optimization objective function and constraints of the virtual power plant by maximizing the net income of the virtual power plant; and S3, according to the predicted output of the clean energy power plant, carrying out scheduling optimization on operating parameters of the virtual power plant through the dual carbon amount model. The method of the invention has the advantages of enabling the power plant to obtain better operation benefits, maximizing the net income during the scheduling period, obtaining more significant carbon emission reduction benefits and higher economic benefits, and having better economy and low carbon performance.

Description

technical field [0001] The invention relates to the technical field of dispatching of power plants, in particular to a method for dispatching optimization of a carbon capture virtual power plant. Background technique [0002] With the aggravation of the greenhouse effect and energy depletion, energy conservation and emission reduction has become the consensus of all sectors of society, and thermal power units, as large emitters, have a huge responsibility. In order to promote low-carbon electricity, it is necessary to vigorously develop clean energy, including non-polluting, or energy that meets certain standards for pollutant emissions. Wind power is considered to be the most representative renewable and clean energy because of its clean and pollution-free, mature technology, low cost, flexible installation and many other advantages, and it has developed rapidly. However, due to its strong intermittency and strong volatility, wind power is difficult to be directly dispatch...
