A PV-WEC Based Microgrid System incorporating Hybrid Islanding Detection Technique

Abstract

This paper investigates the aspects of microgrid formed with distributed energy sources such as Photo Voltaic (PV) solar and wind. Detecting Islanding in a microgrid has become a major challenge in electrical power systems. This project proposes a combination of three islanding detection method, namely voltage unbalance (VU), total harmonic distortion (THD) from passive method and Sandia frequency shift (SFS) from active method. The proposed strategy consolidates the benefits of both active and passive techniques. Moreover, since this project uses the benefits of the SFS method it will not change the system variables and will not lead instability due to any disturbance.
