The idea of reshaping existing centralized electricity networks to decentralized small scale local power networks namely micro-grids, operating whether autonomous or interconnected to main distribution grid, became an important discussion. Islanding of a generator inside the micro-grid can cause problems in operation and management of the network; therefore proper islanding detection is crucial. This...
This paper presents a comparison study of two major distributed generation islanding detection methods including rate of change of frequency (ROCOF) and over/under frequency (OUF) techniques which could be used for Provincial Electricity Authority (PEA) distribution systems. The analysis is based on the detection time in different scenarios and false operations. Two practical distribution systems...
