Renewable energy penetration in the low‐voltage grid faces several limitations due to current topology. Master/slave micro‐grids could help solving these issues, by offering additional services such as power management of distributed sources. In some cases, produced sources exceeds local consumption grid. The consequent reverse flow can be either dangerous (for medium voltage) or impossible a micro‐grid with limited storage). droop characteristic commercial inverter exploited avoid this behaviour. However, stability problems arise low phase‐locked‐loop (PLL) bandwidth. This study investigates solution depending on bandwidth PLL generation
