Abstract

This paper presents a robust voltage sensorless droop control strategy of microgrid to implement power control in a cost-effective and high-reliable way. Virtual flux (VF) algorithm is first proposed to estimate output voltage of inverters without using voltage measurement. Then, the effect of parameters perturbation on accuracy of voltage estimation is analyzed. Furthermore, the robust voltage sensorless droop control strategy is developed to implement power control based on the proposed voltage estimation in power control loop and voltage control loop. Simulation results show that the proposed droop control strategy is able to perform desirable control performance without using voltage measurement even if the parameters perturbation happens, which thus improves system reliability and reduces operation cost of microgrid.
