A fault analysis method for microgrids consisting of inverter interfaced distributed generators

摘要

Based on the steady-state characteristics of Distributed Generators (DGs) in a microgrid a fault analysis method has been developed using Matlab-Simulink phasor analysis tool. Droop control and current limiting are included in the steady-state DG models. The method can be applied for both fault and load flow analysis of small and medium scale distributed generation networks in the Simulink environment and can be a key approach in the development of computational iterative methods to be used for the analysis of large networks. The steady-state modelling results are compared and validated with dynamic simulation results of the same microgrid.
