Low-carbon economic dispatch of Photovoltaic-Carbon capture power plant considering deep peak regulation

Abstract

Retrofitting Coal-fired Power Plants (CFPPs) with carbon capture equipment not only reduce carbon emissions but also provide a deeper peaking depth to accommodate renewable energy. Nevertheless, there exist no studies addressing the economics of deep peaking of Carbon Capture Power Plants (CCPPs), and few studies concerns the synergistic dispatch of PV-CCPP. Therefore, this study analyzes the deep peaking characteristics of CCPP and proposes a low-carbon economic dispatch model for PV-CCPP. Case study shows that the typical daily peaking depth of CCPP is reduced by 72%, the carbon emission reduction is 4263t, and the annual system economy is improved by 43%. Taking into account the peaking compensation helps to improve the system economy, but the carbon emission reduction is slightly reduced.
