Analysis of the Operation Conditions Optimization of Distribution Power System Based on Model Structure

The study of the relationship between the length of lines extending and transmission power is an important issue.The solve of this issue is based on the calculation of power flow,whose precision need distribution power system model structure to ensure.The particularity of distribution power system make the algorithm and model structure which are widely used in transmission power system be incapable.The existing load models and algorithms were selected,amended in the paper.The author choose a suitable load model structure,improve the accuracy of the calculations and make the length of expanded lines and the transmission power math better than before.The results of the study has theoretical and project value.
