| Abstract: When several parallel inverters are in islands operating mode, the droop control scheme is usually used to control the inverters. The droop control method enables the inverters of a Micro-Grid to control the voltage and frequency of the network in a decentralized regulation behavior. The drop control method also enables the inverters to share the required active and reactive powers of the load between themselves. This paper focuses on some of the limitations of single phase parallel inverters using the drop control characteristic in island operating mode. Some controller algorithms have been proposed to pursue the reactive power sharing constraints and to reduce harmonic voltage disturbances at the PCC in island mode. The empirical results show the suitability of controller algorithms to achieve reactive power sharing and improve voltage harmonic disturbances in PCC. |
