“…power transformers, motor drives, wind energy conversion systems, and micro-grid systems). In addition, the WPT-based DDC has been tested for anti-islanding protection of inverter-interface DGUs, where it has shown simple and non-intrusive implementation, along with reliable and accurate performances [18], [25]. The application of the WPT-based DDC for anti-islanding protection of cogeneration systems has to consider the following concerns:…”

“…Such accommodations can be established by processing the d − q-axis components of s a , s b , and s c . Converting s a , s b , and s c into their d−q-axis components (s d and s q ) relocates their frequency contents into separate frequency bands, and simplifies extracting the WPT high frequency sub-bands [18], [25], [26].…”

“…This anti-islanding approach has shown promising performances in terms of the accuracy, reliability, speed, and insensitivity to loading levels and harmonic distortions. In this anti-islanding method, desired signatures are obtained using the wavelet packet transform (WPT), when applied to the dq0 components of PCC instantaneous 3φ apparent powers (s d and s q ) [18]. The islanding condition results in concentrating significant energy in the high frequency sub-band, which is obtained from the WPT processing of s d and s q .…”

In this paper, the performance of a passive antiislanding method is experimentally tested for three phase (3φ) cogeneration systems. The tested method is based on determining the wavelet packet transform (WPT) high frequency sub-bands present in the d − q-axis components of instantaneous 3φ apparent powers (s d and sq), when evaluated at the point of common coupling (PCC). This passive anti-islanding method is founded based on the nature of instantaneous 3φ apparent powers that have components continuously exchanged between both sides of PCC. An islanding condition can be considered as a transient disturbance that creates non-periodic and non-stationary high frequency components in s d and sq. These frequency components can be parameterized by WPT high frequency sub-bands, which can provide accurate detection of the islanding condition. The d − q WPT-based anti-islanding method is tested for a 3φ co-generation system under various loading and power delivery conditions. Performance results reveal accurate, fast, and reliable detection and response to the islanding condition.Index Terms-3φ co-generation systems, anti-islanding protection, d − q-axis reference frame, and the wavelet packet transform.

“…In the advancement of WT, other hybrid techniques, such as the neuro-wavelet, robust wavelet and artificial neural network techniques, have been developed [19], [20]. The application of these hybrid techniques delays the detection time [21]- [23]. To achieve a rapid and accurate detection of electrical grid status, we propose a hybrid FRWPT based anti islanding scheme in this study.…”

This work mainly discusses an accurate and fast islanding detection based on fractional wavelet packet transform (FRWPT)for multibus microgrid systems. The proposed protection scheme uses combined desirable features retrieved from discrete fractional Fourier transform (FRFT) and wavelet packet transform (WPT) techniques, which provides precise time-frequency information on minute perturbation signals introduced in the system. Moreover, this study focuses on the design of decoupling control with a distributed controller based on state feedback for the efficient operation of microgrid systems that are transitioning from the grid-connected mode to the islanded mode. An IEEE 9-bus test system with inverter based distributed generation (DG) units is considered for islanding assessment and smooth operation. Finally, tracking errors are greatly reduced with stability improvement based on the proposed controller. FRWPT based islanding detection is demonstrated via a time domain simulation of the system. Simulated results show an improvement in system stability with the application of the proposed controller and accurate islanding detection based on the FRWPT technique in comparison with the results obtained by applying the wavelet transform (WT) and WPT.

“…Active methods have small non-detection zones (NDZ), however, they often impact negatively on the power quality of the EPS [6][7]. Passive methods use only the local measurements without injecting any disturbances into the EPS, and thus do not impact negatively on the power quality of the EPS [8][9]. Passive methods are independent of DG control algorithms and can easily be combined with other islanding detection algorithms to achieve better detection performance.…”

This paper proposes a passive islanding detection method based on computing a set of frequency dependent reference impedance magnitudes and comparing them with the measured impedance magnitudes at the point of common coupling (PCC). The reference impedance may be identified online over a selected frequency band from the measured voltage and current at PCC. Islanding is detected when the magnitude differences between reference impedance and measured impedance over the chosen frequency band are smaller than a preset threshold. Robustness of the proposed method is verified in a distribution network, the method avoids misdiagnosing islanding condition as normal condition. Performance analyses are discussed from two perspectives of non-detection zone (NDZ) and fault detection zone (FDZ). By combining the under voltage/over voltage (UV/OV) and under frequency/over frequency (UF/OF) methods with the proposed method, the NDZs of UV/OV and UF/OF methods can be reduced.
