Abstract
The carbon capture(CC)and power to gas(P2G)devices can utilize the abundant new energy of the system to capture the carbon emissions generated by thermal power combustion and generate usable gas,forming a carbon resource recycling chain.In order to reduce the carbon emission of the power system,promote new energy absorption,and improve the operation flexibility of the power system,an integrated system architecture including CC and P2G is proposed and its optimization operation model is designed.The operational characteristics of power flow and carbon flow in this architecture are mainly discussed.Considering the benefits of carbon emission trading under the quota system,an optimized operation model for the integrated system of wind-PV-thermal-storage with CC-P2G is proposed,aimed at maximizing the comprehensive benefits of the integrated system and taking the operation characteristics of various equipment as constraint conditions.Furthermore,the effectiveness of the CC-P2G system in improving new energy consumption capacity and system operation efficiency is verified.The results show that the participation of the CC-P2G system needs to be effectively coordinated with market mechanisms such as carbon emissions quota trading,which can reduce the overall carbon emissions of the system and improve its operation efficiency.
