Through the noumenon algorithm as well as the control of speed governor and excitation controller, this control technology mimics the operation and control characteristics of the synchronous generator in a power system, so the flexibility and reliability of control of microgrid inverters are improved, and the stability of voltage and frequency and the power balance in the power system are maintained effectively. Simulation and experimental results show that, microgrid inverters with this new control have good control characteristics of power sharing and grid-connected preparation, so inverters can adapt to all kinds of operation modes of microgrid and meet the control requirements.
