# Non-Line-Impedance-Synthesized Power Sharing Control in Microgrid Using On-Demand Power Feeding

## Main Article Content

## Abstract

A method of power sharing control in the islanding operation of microgrid is proposed in this paper. The proposed approach formulates the power generation of each DG by the relationship of power-angle control, in which the magnitude and angle of the generating voltage are adjusted to follow the change of demanding power. By comparison to the previous work, the new method does not need the value of line impedance, connecting between DG and the common bus, to incorporate the control function. The method, limiting the output power and preventing power consumed by the DG, is also improved. The new method of power-angle control demonstrated that without using the knowledge of line impedance, the suitable power sharing point in the microgrid could also be tracked within each DG’s capacity autonomously. Simulation and experimental results demonstrate the validity of the proposed control.
