Triple‐harmonic‐droop control strategy for accurate harmonic power sharing in low‐voltage islanded microgrids

This paper proposes a power sharing control scheme for electronics interfaced distributed generation to attain accurate harmonic dispatch as well unbalanced sharing. The proposed controller is composed of two main blocks: 1) unit, which leads an sharing, and 2) individual triple-droop units separately applied the unit each phase, properly provide For this purpose, virtual conductance concept developed inherent impedance inverter under non-linear load conditions. As result, fundamental performance accuracy ensured. Simulation results from islanded microgrid prototype using CIGRE low-voltage distribution network are provided validate effectiveness method.
