and low-carbon operation are the inevitable conditions for building a new energy system. This work aims to study the low-carbon economic dispatch of an integrated energy system (IES) considering an oxy-fuel combustion power plant (OCPP). Firstly
the carbon trading mechanism is taken into consideration when building the OCPP-IES architecture. A cooperative operation mode integrating the OCPP oxygen generator and P2G is suggested
along with the operation features of P2G in OCPP and IES. Secondly
the IES optimal scheduling model with OCPP is established with the lowest IES operating cost as the target. According to the surplus of renewable energy
it is divided into two scheduling modes to reduce the cost of oxygen production. The non-linear models are converted into linear models using the piecewise linearity approach
and SCIP then determines the best scheduling plan. Finally
the feasibility of the proposed method is verified by setting five scenarios
and the calculation results show that the proposed scheduling method can further reduce the system operation cost and reduce carbon dioxide emissions.
