Research on grid structure and equipment combination mode to improve the reliability of intelligent distribution network power supply

To improve the reliability level of intelligent distribution networks, it is often not possible to implement a single measure, but rather to combine and implement different reliability improvement measures. Therefore, this article studies the corresponding changes in the sensitivity of other measures after a change in a major reliability improvement measure, and based on this, provides the combination relationship of different measures. In addition, a combination analysis of reliability improvement measures was conducted for different stages of power grid development, and effective ranking of measures at different power grid levels was obtained. Further provide the optimal combination model of reliability improvement measures and the formulation process of the optimal improvement strategy and calculate the reliability improvement strategy combination model for each stage of the city center, urban area, and rural area based on this. This provides clear methodological guidance for improving the reliability of prefecture level power grid companies.
