Distribution Network Reliability Investment Strategy Based on Multi-Factor Index Value Sensitivity Analysis

To obtain the distribution network investment strategy based on reliability multi-factor indicator value analysis in the new power system, firstly, the value judgment of distribution network reliability multi-factor indices is carried out, and the sensitivity of high-value factors is analyzed. Then, the reliability cost and benefit are calculated, and the investment strategy based on reliability multi-dimensional factors is proposed. Finally, select a city distribution network, calculate the value and sensitivity of reliability factors, and put forward the optimal investment strategy for each region. The results verify that this method can make precise investment, thus minimizing investment while achieving the desired reliability level.
