“…The approximation can be resolved many times with detail and approximation. That is, at higher resolutions, the lower-frequency components are extracted [17,18]. In this study, to utilize the feature of the switching surge with high frequency, we utilize the coefficient of the detailed component of level 2 (d2).…”

“…Several types of mother wavelet (MW) exist, including Haar, Daubechies (db) N, Symlets N, Biorthogonal N, and Coiflets N. MWs can be classified according to their length and characteristics [17][18][19]. Furthermore, because the wavelets used in signal analysis can be obtained by scaling and shifting the MW, the selection of the MW is extremely important.…”

“…The fault resistance is 1 Ω, and the fault type is a single line to the ground (SLG) fault. In the case of the I feeder, the fault occurs at 0.1 s and the fault Section is determined at 0.15 s. The tie switch is subsequently closed at 0.2 s. For the J feeder, a fault occurs in 0.2 s. We used the electromagnetic transient program (EMTP) to extract the voltage waveform after system modeling and MATLAB to perform wavelet transform [18,[23][24][25]. We extracted 120 samples per cycle when extracting the voltage waveform from EMTP.…”

“…Wavelet transforms (WTs) have been used in power system protection because they can be used in a wide range of frequency bands. In [17,18], WT was applied to develop the reclosing algorithm in a distribution system. In [19,20], WT was applied to fault detection and classification.…”

Owing to the increase in renewable energy, microgrids (MGs) are increasing. A MG has a small loop-type grid configuration. In the loop MG, challenges in protection such as maloperation of protection relay may occur owing to bidirectional current flow. Herein, we propose a new protection scheme in the loop MG. Considerations for protection in loop MG and fault characteristics are analyzed. Based on these, a new index to solve the considerations for MG protection are proposed using a wavelet transform. Furthermore, the new protection scheme based on the coordination with tie switch using the proposed new index is proposed. To verify the proposed scheme, the MG and the proposed scheme are modeled using the electromagnetic transients program and MATLAB. Various simulations according to the fault location and the success/failure of fault section separation are performed. Simulation results indicate that the power supply on the original feeder can be maintained by proposed method.

The connection of distributed generation (DG) and a battery energy storage system (BESS) in distribution systems has recently been increasing. However, little research has been conducted on the reclosing of the distribution system when both the DG and BESS are connected. Therefore, this paper proposes a new reclosing method for a distribution system with a DG and BESS. The proposed method also has a circuit breaker (CB) installed in the distribution line. A CB close to the DG and BESS is first reclosed after a fixed dead time and, then, the fault clearance is detected using the current flowing to the fault point. Once the fault is cleared, the reclosing of the CB at the source side is attempted after completing a synchronism check. The proposed method is modeled using an electromagnetic transient program. We perform various simulations according to the capacities of the DG and the fault clearance time, and analyze the simulation results. The simulation results show that steady-state power is supplied to the load from the DG and BESS before reclosing to prevent outage, and that the reclosing is successfully performed.

Distributed energy resources (DERs) such as wind turbines and solar panels have fluctuating power generation profile. Also, uncertainty of DERs & loads can bring about complexity in functioning of protection for Microgrids (MGs). Thus, the operation of classical protection methods used in distribution networks may fail for MGs. In this context, this study presents a new protection methodology for discriminating between uncertain and asymmetrical / symmetrical events in MG. A detection method using covariance analysis of wavelet transform (CAWT) and a classification method based on fuzzy logic controller (FLC) using this analysis are presented. The proposed methods are evaluated under various conditions, including fault resistance, fault inception angle, and fault location. Furthermore, variation of solar irradiance levels and source strength has been taken into consideration to validate the performance of the proposed protection methodology. An advantage of the proposed methodology is that the relationship among phases using a covariance analysis proves the presence of the fault. Another advantage is that the discrimination between uncertain and ASF&SF events was discussed, and the faulted phase(s) was/were accurately identified through FLC. Besides, the efficiency of introduced CAWT&FLC-based methods was confirmed on MG configurations such as radial and mesh. In addition, the presented protection methodology became more efficient when combined with the detection of uncertain events.
