Abstract: To overcome the problems of inaccurate calculation results and long calculation time in traditional methods, the paper proposes a renewable energy carbon reduction calculation method based on power flow distribution matrix. First, we calculate the AC current of renewable energy system lines. Secondly, power flow distribution matrix is constructed to realise generation power allocation. Then, the REDD coefficient method is used to obtain the REDD before the use of renewable energy. We then build the objective function of REDD accounting, and solve the REDD results after the application of renewable energy. Finally, the difference between the REDD before and after use is calculated to obtain the final REDD reduction accounting results. The results show that the accuracy of this method can reach 99.6%, and the time consumption is only 25 s, indicating that this method can analyse the effect of REDD reduction.

Keywords: power flow distribution matrix; AC current; renewable energy; REDD reduction; AC current.
