I. Introduction
With the aggravation of greenhouse effect and fossil energy depletion, the development of clean energy and energy conservation and emission reduction has become the consensus of all sectors of society. In order to promote low carbonization of electricity, it is necessary to vigorously develop clean energy and reduce pollution emission [1]. Using carbon capture technology to transform thermal power units into carbon capture power plant (CCPP) can significantly reduce the carbon emission intensity, which is of great significance for power low-carbon.
