Abstract

Abstract: Aiming at the problem of carbon utilization and economic operation of the new type of carbon capture and Cogeneration gas unit, a virtual power plant converged with wind power and power-to-gas (P2G) was constructed. The emitted CO₂ was captured and transported to P2G as the carbon raw material for power-to-gas, so as to realize carbon recycling in virtual power plants. The optimal operation model of the virtual power plant was established. The goal was to maximize the benefit of the virtual power plant, and the decision variables were CO₂ capture rate, thermoelectric ratio, electric output of the thermal power plant and electric to gas power. The simulation results show that the virtual power plant in this aggregation mode can obtain higher economic benefits, better wind power consumption, and lower carbon emissions. This virtual power plant and its carbon recycling method are an effective way to reduce wind curtailment, reduce emissions, and enhance carbon utilization. It has significant economic and social benefits.

Key words: gas-power plant carbon capture, power to gas, carbon recycling, wind power consumption, virtual power plant
