Power system transient stability simulation method and device, electronic equipment and storage medium

The invention provides a transient stability simulation method and device for a power system, electronic equipment and a storage medium. The method comprises the following steps: acquiring a state variable and an operation variable of a current simulation time step in the power system; according to the state variable of the current simulation time step, the operation variable of the current simulation time step and a pre-obtained differential neural network model, solving a differential algebraic equation to obtain a state variable of a next simulation time step and an operation variable of the next simulation time step; updating the current simulation time step value to the next simulation time step value; when the next simulation time step does not reach the preset simulation total time, repeatedly executing the steps; and when the next simulation time step reaches the preset simulation total time, outputting a transient stability simulation result of the power system. According to the method, the different
