Low-Carbon Economic Dispatch of P2G-CCS Integrated Energy System Considering Wind-Solar Uncertainty

Abstract

In order to improve renewable energy consumption, achieve low carbon emissions and promote the development of integrated energy systems, this paper proposes a low carbon economic model for integrated energy systems that considers wind-solar uncertainty and P2G-CCS (power to gas and carbon capture system, P2G-CCS) coupling. The uncertainty of the wind turbine and PV output is expressed as an uncertainty interval, and the uncertainty of the wind turbine and PV output is determined by using robust optimization; then the P2G-CCS equipment is added to this model. The model is solved by the Cplex solver, and the analysis proves that the model proposed in this paper can reduce the carbon emission of the system while effectively saving the operation cost, which is reasonable and practical.
