Abstract
The invention provides an adaptive inertial control method based on IIDG (Inverter Interfaced Distributed Generator) of a virtual synchronous motor. By building an adaptive virtual inertia and IIDG output frequency model, the adaptive control sensitive factor is selected from a model according to the virtual synchronous motor dynamic response features; the adaptive inertial upper and lower limits are selected from a model according to the energy storage configuration constraint; the IIDG optimization control strategy is obtained. The control on the grid-connected inverter distributive power supply can be realized, so that the IIDG output is more stable; the interference on the system can be well handled; meanwhile, the characteristics of small overshoot and fast response are realized; the ultra-high dynamic features are realized.
