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. 

Dr. D. N. Gaonkar received his M-Tech. degree in Power and Energy Systems from National
Institute of Technology Karnataka, Surathkal, India in the year, 2003. He obtained his Ph. D.
degree in Power Systems in the year, 2008 from Indian Institute of Technology (IIT), Roorkee,
India. He was a visiting scholar at the University of Saskatchewan Canada. He also visited Center for Future Energy Systems (CFES) at Rensselaer Polytechnic Institute (RPI), Troy New York and Energy Reliability &Security Laboratory at Michigan State University (MSU) at East Lansing, USA for research interaction. He has edited and written a chapter in the book titled DISTRIBUTED GENERATION, which is published by INTECH publication Austria. He is the member of the task force committee on distribution and distributed generation, Under National Perspective Plan(NPP) of Ministry of Power Government of India. He has published many
papers in reputed international journals and conferences. He is working for research project on a microgrid as a principal investigator sponsored by ministry of power Govt. of India through CPRI Bangalore. He is the senior member of IEEE and member of IE india, life member of ISTE and SSI. He is also the Execom member of IEEE PES Bangalore chapter for the year 2014 and
2015. His main research interests are in the area of power system operation and control,
distributed generation systems and power electronics. Presently, He is an Assistant professor in the Department of Electrical and Electronics Engineering NITK Surathkal India.
