Description

technical field [0001] The invention belongs to the field of optimal operation of power systems, and specifically relates to a low-carbon optimal operation method considering the cooperation of carbon capture power plants and photovoltaic power generation. Background technique [0002] Under the guidance of the "dual carbon" goal, carbon reduction technologies represented by carbon capture power plants and clean energy represented by photovoltaic power generation will become an important force to promote the low-carbon transformation of the power system. On the one hand, carbon capture power plants can capture CO 2 The way to reduce the output of the unit and improve the power system’s ability to accept photovoltaics, but in the process of CO 2 When harvesting, it will additionally increase the coal consumption of power generation. On the other hand, after large-scale grid-connection of photovoltaic power generation, its randomness and volatility will reduce the operationa...
