SYNOPSIS
Grid integration of distributed generation is expected to play an important role in the future
electricity market, due to the increasing demand of power. Distributed generation including
photovoltaic, wind farms, fuel cell and micro turbines can resolve the rising concerns for
environmental safety while supplying a reliable, cost effective power. Despite all the advantages,
so many critical issues like need for improved relay schemes, network redundancy and safety
have to be considered for effective grid integration. Islanding is one among those prominent
issues, which can seriously impair the safety of the generators and customer loads, if not
properly dealt with.
Recently several islanding detection methods are proposed in literature. Among these, one of
the important method is active detection method that injects reactive power intermittently based
on the load resonant frequency. Detailed analysis of the method put forward some problems
under different conditions. To mitigate these flaws, a new hybrid islanding detection method is
presented in this work. This new method combines the above suggested active method with a
novel passive algorithm. This passive algorithm relies on the transient response characteristics
of the islanded system for generating islanding suspicion signal and avoids the continuous
injection of disturbance. The proposed method proved to detect all probable islanding situations
with minimum run on time compared with the conventional method. The performance of the
proposed islanding detection method is studied using a synchronous generator based wind
system through simulation results.
