A high proportion of new energy connected to the distribution network will lead to uncertainty in the flow of electricity,and the accuracy of estimating the maximum consumption capacity of new energy is not high.A precise estimation method for the maximum consumption capacity of high proportion new energy in distribution networks has been proposed to address this issue.Determine physical quantities that reflect the magnitude and fluctuation characteristics of high proportion of new energy output,and analyze the characteristics of high proportion of new energy output under different weather conditions.Build a high proportion new energy access distribution network model,calculate the current consumption capacity and voltage threshold risk of high proportion new energy access nodes,compare it with the set voltage threshold,and obtain accurate estimation results of the limit consumption capacity.The experimental results show that there is only a maximum error of 200 kVA between the estimated maximum absorption capacity value of the proposed method and the experimental data,indicating that the estimation results of this method are more accurate.
