Abstract:

The use of Distributed Generation (DG) and Microgrid(MG) systems, which integrate with the utility grid via power electronic inverters, is rapidly growing in the energy sector. Anti-islanding protection is implemented to prevent the unintended flow of electricity back into the utility grid during power outages. The automated switchover of the microgrid to stand-alone mode is addressed as a solution to this problem, which allows the local load to be powered by the microgrid during grid failures. Intelligent islanding techniques have drawn more interest since they are faster and more accurate than conventional methods. This paper describes an improved SVM classifier-based islanding detection in a microgrid system that is connected to an IEEE 6-bus test system. The high accuracy and prediction speed enable the microgrid system to switch to stand-alone mode when an islanding event is found to occur. The proposed method demonstrates a smooth mode transfer between grid-tied and stand-alone modes. Simulation results show that the SVM model-based approach for the islanding detection technique is highly reliable with high accuracy and detection speed. The non-detection zone is negligible and ensures uninterrupted power supply to the local loads even in case of grid failure, by islanding operation.
