In-plant optimizing operation method for carbon capture unit under transaction of carbon emission permits

Abstract

The invention discloses a carbon capture power plant operation method for a carbon capture power plant considering carbon emission permit transaction and belongs to the field of power plant operation and control methods. The carbon capture power plant operation method comprises a first step of building a carbon capture level optimizing model considering electricity generating cost, carbon emission permit purchase cost and electricity selling loss cost of a power plant, and obtaining a carbon emission permit price sensitive interval, and a second step of obtaining the carbon emission permit phase cost by adoption of an alpha-super quantile method, and building a carbon capture level random optimizing model considering fluctuation of carbon emission permit price. The carbon capture power plant operation method for the carbon capture power plant has the advantages that economic benefit maximizing considered from the view of a generation company effectively achieves flexible and economical operation of the carbon capture power plant, the alpha-super quantile method effectively avoids contradict meaning caused by an at-risk conditional value method, and solves a random optimizing problem in the mathematical meaning, and the sensitive interval plays a meaningful role in reasonable pricing of carbon emission permit, micro-control of the carbon emission permit price, and guiding of carbon market.

Description

technical field [0001] The invention belongs to the field of power plant operation and control methods, and relates to a carbon capture power plant operation method considering carbon emission right trading. technical background [0002] my country is the global CO 2 One of the countries with the largest emissions, in the context of vigorously developing a low-carbon economy, the power industry is a CO 2 Carbon capture and storage (CCS) technology is considered to be one of the effective ways to achieve low-carbon development of electricity. With the support of CCS technology, a thermal power plant becomes a carbon capture power plant after introducing a separate carbon capture system. The capture energy of carbon capture power plants generally accounts for about 20% of the power generation power of the power plant. Therefore, a reasonable coordination between capture energy costs and carbon emissions to achieve flexible and economical operation of carbon capture power pla...

AI Technical Summary

Problems solved by technology

The level of carbon capture changes with the price of carbon emission rights, but the price of carbon emission rights is fluctuating, with great uncertainty, so it is difficult to rationally optimize the level of carbon capture
