Beschreibung
Zusammenfassung:	The invention relates to an independent micro-grid virtual inertia optimal configuration method and device, equipment and a medium. The method comprises an independent micro-grid optimal inertia configuration part and a rapid frequency index evaluation part. According to the independent micro-grid optimal inertia configuration part, renewable energy source load shedding amount, energy storage charging and discharging amount and related parameters are used as optimization variables, a virtual inertia optimization configuration model considering independent micro-grid transient frequency nonlinear constraint is constructed, the virtual inertia optimization configuration model is solved, and an independent micro-grid optimal inertia configuration scheme is obtained. According to the rapid frequency index evaluation part, Latin hypercube sampling is carried out on the frequency dynamic response model of the independent micro-grid, correlation parameters influencing the frequency dynamic response are obtained, the
