Look-ahead dispatch considering the integrated carbon and electricity network constraints

Abstract

Carbon capture and storage technology are becoming a promising method to mitigate the CO2 emissions from the power generation sector. After retrofitting the conventional power plants with carbon capture devices and carbon transmission infrastructures, the operating characteristic of power plants is changed. To adapt to the new dispatch pattern, this paper established a multi-period lookahead dispatch model with generation cost and carbon emission cost as objectives, and the operating characteristics of carbon capture power plants (CCPP) as well as carbon transportation system are taken into account. Finally, an integrated IEEE 118-bus test system combined with the 14-node carbon transmission system is applied to validate the effectiveness of the proposed model. The effects of carbon transmission network on the dispatch results are discussed, and the sensitivity analysis of the carbon price and carbon transmission capacity are also conducted on the test system.
