Strategy II has good tracking performance for both active and reactive power with an acceptable settling time. The low PCC voltage has a larger impact for Strategy I because its power control loop is a current control
Therefore, researching the switching strategies for bidirectional energy storage inverters between grid-connected and off-grid modes plays a crucial role in the stable operation of microgrids.
Based on the established model, the oscillation mechanism of the grid-connected inverter system is revealed: the inductance current flowing through the grid impedance can produce a voltage disturbance,
The proposed method has only been tested on a single inverter unit, both in grid-connected and off-grid modes. A scheme for connecting multiple inverters in parallel would be more complex.
