Distributed Generation(dg)sources,predominantly renewable energy-based,such as solar photovoltaic and wind energy sources,have significantly penetrated into power system *** high penetration of dg sources may lead to the formation of unintentional islands,which is hazardous to both the equipment and personnel,if *** this paper,46 passive parameters are considered to find out which candidate(s)are promising for detecting sustained unintentional islands and avoid false dg *** 46 parameters are derived from point of common coupling(PCC)voltage,dg output current,frequency,power factor angle,active and reactive *** these parameters are tested on standard IEEE 13 and 34 bus distribution networks,integrated with inverter-interfaced dgs at different locations for different penetration levels in the MATLAB/SIMULINK *** parameters are tested for different islanding events(comprising of various local loads,such as conventional parallel RLC resonant load,R,RC,and RL loads)and for different non-islanding *** parameters are then ranked accordingly by a suitable averaging approach based performance ranking *** this analysis,the best candidates are obtained for detecting inverter dg islands at single-point(or single PCC)locations and multi-point(or multiple PCCs)*** best passive candidates are obtained for different island scenarios from which a set of promising islanding detection indicators are proposed.
