A Study on Power Sharing between Parallel Inverters in Micro grid under Mismatched Feeder Impedances

In a micro grid with multiple DGs, the system experience the issue of active and reactive power sharing between the inverters. In this context, this paper presents the implementation of droop control method to equally share the active and reactive power in a micro grid with inverters operating in parallel. Further this paper also addresses the issues pertaining to the feeder impedance mismatch effecting the sharing of P and Q. To realize its operation the system is designed in PSCAD software. Further this paper also addresses a future scope for a possible solution.
