The traditional power droop controllers are commonly used in distributed generation (DG) units to share the loads among the parallel inverters. However, the parameters of the power transmission and distribution line in microgrid are small and generally presented high resistance-to-inductance (R/X) ratio which will seriously influence the performance of the traditional power droop controller, even leading to instability
