Abstract: Incredible growth in demand of electricity with efficient, reliable and eco-friendly power has motivated progress of distributed generation (DG). This is located at distribution system and now a day renewable energy sources used as a DG. But problem of using DG is unintentional islanding, which has perspective to make voltage and frequency out of synchronism and can damage equipment along with thoughtful issue of worker safety. Hence system should identify islanding and avoid its adverse effect. There are many islanding detection methods (IDM) but there is no such technique by which all the problems related to islanding being solved. In this paper new islanding detection technique is proposed on the basis of voltage ripple at inverter side of micro-grid base system. Its performance will be verified under wide range of operating condition in MATLAB/Simulink software.
