Analysis of influencing factors and path selection of carbon peak in residential substation areas

With the continuous improvement of the living standards and quality of urban residents, the electricity and energy consumption in residential substation areas have maintained a rapid growth rate. Carbon peaking in residential substation areas has become an urgent issue to be studied. In this paper, a direct carbon emission model of residential substation areas is established. Then a carbon emission reduction model is proposed with the help of three technologies such as building new photovoltaic systems, increasing the proportion of domestic electrification, and reducing power grid loss. A simulation studies the impact of various carbon reduction technologies on carbon emissions in residential substation areas under different scenarios. The results show that: 1. under the current condition of slowing population growth, when the growth rate of per capita energy consumption is comparable to the reduction rate of regional carbon emission factors, carbon peaking in residential substation areas can be achieved by applying certain carbon reduction technologies in 2030; 2. under the current carbon emission factors, replacing gas with electric energy for domestic use cannot achieve carbon emission reduction; 3. among various carbon reduction technologies in residential substation areas, the effect of constructing photovoltaic power supply areas is the most obvious. Therefore, this paper suggests that to achieve fast carbon peaking in residential substation areas, we should reduce the electricity-carbon factor of the regional power grid, and vigorously carry out photovoltaic power supply construction.
