Low-Carbon Dispatch Optimization of Multi-energy complementary Integrated Energy System Combining Wind power/ Photovoltaic/Carbon capture

Abstract

Under the low-carbon background, to reduce the carbon emissions of the integrated energy system (IES) and promote the consumption of renewable energy, a strategy of integrated low-carbon optimal dispatch for wind, solar, and carbon capture is proposed. First of all, this paper establishes a joint dispatch model with wind power, photovoltaic, and carbon capture units, which improves energy efficiency and maximizes operational benefits. Secondly, IES is considered to participate in the carbon trading market. Then a low-carbon optimal dispatch model for multi-energy complementarity including wind turbines (WT), photovoltaic (PV), carbon capture, power-to-gas(P2G), combined cooling heating and power (CCHP), and heat storage, is established. Considering physical constraints such as energy conversion and equipment startup and shutdown, the optimization minimizes the economic cost of the low-carbon operation of the system. Finally, the gurobi solver is employed to solve the optimal scheduling model. The results prove that the proposed method can effectively achieve the carbon reduction of IES, and promote wind and solar consumption.
