An islanding detection scheme is developed using pulse compression probing (PCP). A state space system realization is taken from the probing output. The nu-gap metric is applied to compare the measured system to fully intact system and classify it as islanded, or grid-connected. The designed detector displays fast operation, accurate islanding detection results under varying grid condition, and is physically implementable at the terminals of an inverter. The method is verified via electro-magnetic transient (EMT) simulation on a modified IEEE 34 bus test system with randomized loads and simultaneous probing at three independent solar plants, with the probing signal directly implemented into the logic of a switching inverter model.
