Islanding Detection Through Mean of Superimposed Voltage

In a microgrid, unintentional islanding is a threat to its security and stability. Islanding detection within pre-specified operating time is required. In this paper, a new technique MSPV of islanding detection is presented for distribution system which is based on superimposed voltage component. The proposed technique is fast and effectively distinguishes between islanding and different non-islanding situations even in 0% active power mismatch. Microgrid considered for the testing of islanding technique is simulated in MATLAB R2016a.
