Abstract: The carbon generalized system of the preferences（CGSP）is a new incentive mechanism to guide the public to practice energy conservation and carbon reduction, and cultivate green and low-carbon thinking and behaviors.Focusing on the problem that power customers have great potential for energy optimization and carbon reduction but lack of regular incentives,this paper designs a carbon generalized system for energy optimization of power customers based on the underlying CGSP operation logic. Firstly,the emission reduction mechanism of energy optimization on the power customers side is analyzed based on the life cycle of energy supply and demand,and four types of ten low-carbon behaviors are sorted out,methodological models are constructed for each type of the behavior. Secondly, a new CGSP is designed under the supervision of the government,with power grid enterprises as the guiding party and multiple parties involved. Secondly,the service platform is designed systematically for the application.Furthermore,a carbon emission reduction and carbon credits calculation model is constructed for the energy alternative scenario of electric vehicles. Finally,taking the CGSP for charging of electric vehicles in Jiangsu as an example,expected application effects are discussed in detail. With application of the CGSP,the charging capacity is increased by 2 123 kW·h,the total carbon reduction is 37 068 kg,and the incentive coefficient of the average carbon integral at the station is 7.36%,which indicates good incentive effects on the peak-shifting andvalley filling of electric vehicles due to the CGSP.
