Power- and Current-Based Control of Distributed Inverters in Low-Voltage Microgrids: Considerations in Relation to Classic Droop Control

摘要: This paper addresses the matter of active and reactive power sharing among distributed inverters in low-voltage microgrids, particularly highlighting peculiarities two strategies coordinated control based on a master/slave architecture, namely Power- Current-Based Control, comparison to classic droop approach. It is demonstrated that Control present distinct operational features relation control, mostly concerning how are shared inverters. Additionally, it shown differ steady-state operation response time while comparing droop-based methods. Discussions presented simulation results using Matlab/Simulink, comprising microgrid considering different scenarios, such as load changes, existence linear nonlinear loads, well line impedance variations. Experimental validate expected behavior one strategies.
