Static safety analysis method for city-local integrated power grid considering spare power automatic switching

The invention discloses a static safety analysis method for a city-local integrated power grid considering spare power automatic switching, and relates to the technical field of power systems and automation thereof. The method comprises two tasks of establishing a spare power automatic switching action model and performing static safety analysis on the power grid considering the spare power automatic switching action. The method comprises the following steps: respectively establishing a common spare power automatic switching action model and a regional spare power automatic switching action model based on a spare power automatic switching action principle; according to the method, two methods of network topology analysis and spare power automatic switching mapping relation establishment are combined, and common spare power automatic switching and regional spare power automatic switching actions are considered at the same time, namely, the common spare power automatic switching actions are analyzed by adopting
