Accidental Islanding of Distribution Systems with Multiple Distributed Generation Units of Various Technologies
نویسندگان
چکیده
The system response to accidental islanding and effect on anti-islanding detection of distribution feeders with multiple distributed generation (DG) technologies (synchronous machine and inverterbased units) is one major utility concern associated with increasing penetration of DG. Studies have been conducted to evaluate the performance of anti-islanding detection through use of conventional voltage and frequency protection elements, and a non-detection zone (NDZ) defined in terms of real and reactive power mismatch scenarios. However, this NDZ applies to only synchronous generator DG technology, and efforts to characterize system behaviour and performance of anti-islanding detection for systems with mixed inverter and machine units have been limited. This paper investigates the effect of adding inverter-based DG to the system under various real and reactive power mismatch scenarios.
