Abstract

Microgrid (MG) usually adopts droop control to stabilize its frequency and voltage. However, because the line impedance between distributed generators (DGs) is not proportional, the power sharing cannot be achieved. In order to solve this problem, a finite-time power sharing approach for MG is proposed. Firstly, the secondary controller is constructed which is composed of voltage regulator and power regulators. Secondly, the reference voltage and frequency are calculated by combination with droop control. Finally, the stability of the system is analyzed and the effectiveness of the method is verified by simulation.
