Research on carbon footprint of substation life cycle

Abstract

With the advancing steadily in the work of “carbon peaking and carbon neutrality” target, the quantification of carbon emissions has become a difficult problem for substation management. Power supply companies in various cities have a large amount of low-carbon investment, but cannot explain the effect and output clearly, which is difficult to meet the purpose of implementing "carbon peaking and carbon neutrality" in the power system. To this end, this paper takes the substation as the object, establishes an abstract carbon model, analyzes the carbon expression and quantification method in various activities of the substation in the construction stage, operation stage, and demolition stage, and defines fixed, continuous and comprehensive carbon emissions to describe the carbon footprint. The research results show that reasonable low-carbon investment can effectively promote the neutralization of the substations carbon footprint. By further adopting long-term energy-saving measures for equipment and sufficient new energy installed capacity, the substation can offset the load consumption in the station through new energy power generation, and achieve carbon neutrality state. In addition, combined with the actual low-carbon design of a substation, this paper introduces the latest design route and actual effect of carbon reduction in substations, which provides ideas for the design and construction of low-carbon substations in the future.
