“…The submodule (SM) can be either a half-bridge or full-bridge circuit, depending on the performance requirements. Unlike half-bridge MMC, full-bridge MMC can be controlled to isolate and tolerate a DC short-circuit fault, which is preferred for safety-critical HRES applications, while at relative higher cost due to the larger number of power devices [103]. Furthermore, based on the number of employed DC sources, the classic MLI topologies can be classified into two main groups, as shown in Fig.…”

A hybrid renewable energy source (HRES) consists of two or more renewable energy sources, such as wind turbines and photovoltaic systems, utilized together to provide increased system efficiency and improved stability in energy supply to a certain degree. The objective of this study is to present a comprehensive review of wind-solar HRES from the perspectives of power architectures, mathematical modeling, power electronic converter topologies, and design optimization algorithms. Since the uncertainty of HRES can be reduced further by including an energy storage system, this paper presents several hybrid energy storage system coupling technologies, highlighting their major advantages and disadvantages. Various HRES power converters and control strategies from the state-of-the-art have been discussed. Different types of energy source combinations, modeling, power converter architectures, sizing, and optimization techniques used in the existing HRES are reviewed in this work, which intends to serve as a comprehensive reference for researchers, engineers, and policymakers in this field. This article also discusses the technical challenges associated with HRES as well as the scope of future advances and research on HRES.INDEX TERMS Hybrid renewable energy sources, hybrid energy storage system, optimization, Power converter, photovoltaic power, wind turbine.

“…For reliability analysis of MMC, the failure rate of the components within the MMC needs to be evaluated. Also, redundancy as a fault-tolerant strategy is applied to increase the MMC reliability [21]. In the followings, the failure rate of power components and the redundancy effect are scrutinized.…”

Detection, diagnosis, and localization of switching faults in electric drives are extremely important for operating a large number of induction motors in parallel. This study aims to present the design and development of switching fault detection, diagnosis, and localization strategy for the induction motor drive system (IMDS) by using a novel diagnostic variable that is derived from discrete wavelet transform (DWT) coefficients. The distinctiveness of the proposed algorithm is that it can identify single/multiple switch open and short faults and locate the defective switches using a single mathematical computation. The proposed algorithm is tested by simulation in MATLAB/Simulink and experimentally validated using the LabVIEW hardware-in-the-loop platform. The results demonstrate the robustness and effectiveness of the proposed technique in identifying and locating faults.
