Accurate load sharing control in autonomous operation of microgrid

The paper investigates the active power and reactive power sharing in autonomous operation of Microgrid with multiple distributed generations. Conventional f-P droop and V-Q droop can not ensure the accuracy of power sharing when line parameters mismatch. A novel scheme for accurate load sharing is proposed, considering the resistor and inductance of transmission line. The scheme presents superior behavior in comparison with conventional method, especially in reactive power sharing. Simulation results prove the good performance for two parallel VSI. Small-signal stability analysis is shown here.
