Research on Flexible Load Control Strategy and Power Supply Reliability Management Based on Sensitivity Analysis in New Type Power System

With the increasing proportion of new energy and power electronic equipment in the power system, the stability of the power system is facing challenges. Overload of transmission line is a common fault problem. The traditional method mainly relies on sensitivity analysis to solve it, but it is limited by the unadjustable characteristic of traditional load. This paper combines flexible load with load sensitivity and Power Supply Reliability and Sensitivity. By adjusting flexible loads such as temperature control air conditioning, electric vehicles and distributed energy storage, the overload branch power of the power system can be adjusted to improve the power supply reliability of the new type power system.
