Assessment of incremental environmental benefits during the construction period of green and low-carbon transmission and substation projects based on PSO-BP algorithm

Under the background of “dual-carbon”, a number of green and low-carbon materials, equipments and processes will be applied in the construction phase of transmission and substation projects in order to reduce the level of carbon emissions. Firstly, this paper introduces the superiority of PSO-BP algorithm compared with the traditional BP algorithm; secondly, it introduces the basic principle and prediction steps of PSO-BP algorithm in detail; then, based on the historical carbon trading data of Shanghai, it compares the advantages and disadvantages of the prediction results of the two algorithms; lastly, it multiplies the reduction of carbon emissions by the predicted price of carbon as an indicator of incremental environmental benefits brought by green and low-carbon construction of transmission and substation projects. environmental benefits.
