“…7 Operation of slip-mode frequency shift method the utility is disconnected, the frequency of the PCC voltage will change and accordingly phase response curve increases the phase angle error and hence inverter becomes instable to operate at utility frequency w 0 . This instability further amplifies the perturbation in the frequency and thus the system will move to another operating point either w 1 or w 2 which is the frequency outside the range of OFP/UFP [44]. Implementation in this method is easy and has comparatively smaller NDZ than passive methods.…”

“…During this method, a miniature energy signal is propelled between the transmitter (T) installed by the side of the utility and the receiver (R) inserted at the DG side. This communication, determination is disturbed at what time islanding occurs and a stopping signal is sent toward PCU or a switch through the receiver in the direction of segregating the load [44].…”

This paper provides an analytical survey of the islanding detection techniques for the distributed generation systems. Islanding phenomena on takes place when the power supply from the main utility is intermittent due to numerous reasons, but the distributed generation keeps supplying power into the distribution networks. Islanding can be dangerous to workers and electrical equipment, even the power grid. Therefore, islanding detection is the priority among priorities. Islanding detection is a precondition of two working modes switching for distributed generation. In this paper, a detailed description followed by the classification of the islanding detection techniques has been made based on features, such as detection time, size of non-detection zone, power quality disturbances, system cost and operation under multiple distributed generation units. The merits and demerits of islanding detection methods are analyzed and summarized in this paper. In this manner, the greatest detection outcome can be achieved by exploiting the merits of each method. This paper is aimed to serve as a convenient reference and guidance value for deciding the islanding detection method for future islanding users in distributed generation system.

This paper proposes a hybrid islanding detection technology including local techniques and remote techniques. A pulse current injection scheme is proposed as active method of local technique to find out non-detection zone. Combine the remote techniques by power line communication scheme with islanding detection completely. Using pulse current injection method can detect islanding system faster than 0.167 cycles. Mixed with the power line communication method it will be fast, stable and accurate technology for distributed generation systems. Finally, this performance follows IEEE-1547 and IEEE-929 standards are validated by simulation and experimental results.Keywords-islanding, distributed generation, pulse current injection, power line communication.

Summary The paper presents a novel detection method based on feature extraction discrete wavelet transform (DWT) combined with artificial neural network (ANN) for identification of islanding condition in distributed generation (DG) system. Islanding detection methods can be classified into two major categories as active and passive methods. The main disadvantages of the passive methods are determined threshold value and related to their large non‐detection zone. The emphasis of the proposed approach is eliminating the aforementioned drawbacks. The DWT allows revealing various hidden features of the signal. The aim of this paper is to determine the best wavelet basis function in order to identify islanding occurrence with higher accuracy and lower decomposition level. The proposed approach requires the measure rate of change of frequency at the DG's terminal, and various features are extracted from DWT then these features used as input into ANN. Also, the performance of the different structures of ANN such as feed‐forward neural network, radial basis function, and probabilistic neural network are compared for islanding detection purpose. The proposed method is simulated and tested in various operation conditions such as islanding conditions, motor starting, capacitor bank switching, and nonlinear load switching. The test results showed that the proposed method correctly detects the islanding operation and does not mal‐operate in the other situations. Copyright © 2016 John Wiley & Sons, Ltd.
