At present,environmental pollution problem caused by energy consumption has become increasingly prominent,and renewable energy cannot be absorbed into the grid smoothly.Therefore,it is necessary to guide and encourage the construction of power supply side and the response of demand side through the power grid access price mechanism.Taking the access service provided by power grid enterprise to the power supply side and the demand side as the entry point,the access charging practice in different countries was compared and analyzed.Based on the theory of price economics,according to China's economic development status,transmission price structure and energy strategy,a shallow access cost recovery model and a hybrid access fee collection method were designed for power supply side access,so as to promote renewable energy access and consumption through price signal.Studying the price guidance mechanism of power grid access service can provide reference for solving the environmental pollution problem caused by energy consumption.
