| Abstract |
This paper studies the effect of configuration changes to a modular inverter-based microgrid using an inertia index. The inertia index is developed based on an analogy between the inertia constant of synchronous generators and control parameters of droop controlled inverters. The effect of modular operation on transient performance of microgrid frequency is studied by using the considered index for an islanded inverter-based microgrid. Based on the inertia index, a control approach that mitigates the change in a microgrid frequency dynamics caused by modular operation is also explored. The effectiveness of the inertia index and control approach is also verified. |
