| Abstract | This paper presents a novel control strategy to operate a low-voltage (LV) micro-grid in grid connected operation mode as well as autonomous operation mode. Depending on the inverter output impedance which is mainly resistive due to the LV cables a proper control strategy based on an unbalanced resistive droop approach is developed. The control strategy is verified by simulating fast changes of power production and simulating excess, shortage and average scenarios. Additionally, the control system can operate in an unbalanced network and can improve the active and reactive power distribution using a data communication system. |
