SVM-based anti-islanding protection for DER near a modern industrial premise.

Detection of the islanding condition of distributed energy resource (DER) is a crucial protection concern as per IEEE standards. Industrial motors, arc furnaces, EV fast-charging station, etc., are loads of serious concern that adversely affect the proper functioning of conventional anti-islanding protection schemes. This paper introduces a novel anti-islanding protection scheme for three-phase inverter-based DER located near/within the premises of a modern industrial consumer. In this work, a modified passive intelligent islanding detection method is employed which uses discrete wavelet transform for extraction of six features from input signals (d-axis voltage, V d and frequency, f) and support vector machine for classification. Models of various loads and equipment are developed and are connected to IEEE 13 bus system to create the test system. Test cases are generated by considering various load conditions and the occurrence of different events in the test system. PSCAD/EMTDC is used for simulation. Reduction in the non-detection zone and detection time compared to the existing methods proves the robustness of the proposed method. [ABSTRACT FROM AUTHOR]
