Hybrid simulation algorithm and device for power distribution system and computer storage medium

The invention discloses a hybrid simulation algorithm and device for a power distribution system and a computer storage medium. Simulation algorithms based on two numerical integration methods of a small-step four-order explicit Runge-Kutta method and a large-step two-level semi-implicit Runge-Kutta method are established respectively; dividing the operation process of the power grid into an electromagnetic transient process and a medium-and-long-term dynamic process by taking an infinite norm of a change value of a voltage or current change rate of each node in the network in each simulation step as a threshold condition, and automatically switching different numerical integration methods according to the characteristics of the two processes. Finally, the explicit-semi-implicit hybrid simulation algorithm for the power electronic power distribution system, which not only ensures the simulation efficiency, but also ensures the simulation precision, is obtained. 本发明专利公开了一种面向配电系统的混合仿真算法、装置及计算机存储介质，通过分别建立基于小步长四阶
