Islanding Detection In Distributed Generation Using A Hybrid Approach

Renewable energy systems can run continuously in one of two ways: grid-connected or stand-alone. The system can run in either grid-connected mode in the first scenario or microgrid or island mode in the second. It is referred to as isolated operation when a decentralized generator (DG) keeps running when there is no external power supply accessible. Due to the fact that it hinders devices from correctly joining, this issue can harm the mesh. Therefore, a hybrid island identification method that combines passive and active is proposed in this study. Islanding issues arise from the deployment of DG units such photovoltaics. The accuracy of islanding detection (ID) will also depend on the number of DG sets in the power distribution system. The suggested DC source system that is linked to a 415 V, 50 Hz grid is tested using the suggested procedure. Performance evaluation of the method using passive and active ID methods. The detection time is shortened by the suggested strategy.
