摘要
Dc microgrids are feasible and effective solutions for integrating renewable energy resources to the power system. However, the operation around an equilibrium point depends on the control strategy adopted for each operation mode. When operating in off-grid mode, droop and maximum power point control are basic strategies employed to regulate the voltage across the dc link considering the lack of communication between the sources. In this context, this work describes some important issues regarding the application of such approaches in microgrids, where active and nonlinear loads such as constant-power loads and constant-impedance loads exist. In this case, the power sources are considered as a set of parallel-connected current sources associated with their respective equivalent resistances. The proposed approximate model allows performing a nonlinear analysis to predict the qualitative behavior of the system due to the reduced number of differential equations. In addition, this analysis provides sufficient conditions to determine the operating points of the system, thus providing reliable design guidelines for the implementation of microgrids.
