Considering the strong exothermic property,power to gas can operate in coordination with the heat accumulator,and the heat released by the methanation reaction of power to gas can be injected into the heat network efficiently in the low load period,which provides a new way to accommodate the wind power.This paper proposed a low-carbon economic dispatch model of wind power consumption considering power to gas heat recovery and heat accumulator.The carbon trading mechanism is introduced.The objective function is to minimize the system carbon cost,fuel cost,abandoned wind cost,electricity to gas cost and gas supply benefit.The constraints of thermoelectric coupling,unit climbing power,power to gas output,heat and electricity power balance are considered.The simulation results show that considering the electricity to gas heat recovery can effectively improve the wind power consumption capacity,reduce the total cost and carbon emissions of the system.Finally,the influence of the unit operation cost of electricity to gas on the wind power consumption capacity and economy of the system is analyzed.
