Abstract
In this paper a fast fault detection method for Microgrid system based on micro-sources equipped with power electronics interfaces is explored. This method provides reliable and fast detection for different types of faults within the micro-grid. The micro-source output voltages are monitored and then converted to dc quantities in the d-q reference frame. Thus, any disturbance at the micro-source output due to any type of fault is reflected as disturbances in the d-q values. The disturbance is used to detect the fault and this leads to the initiation of the associated breaker to isolate the faulted section from the network. Analysis and simulation results are presented for different types of faults within the micro-grid.
