Special Issue Information

Dear Colleagues,

We are currently running a Special Issue on “Microgrids and Fault-Tolerant Control” for the SCIE-indexed open access journal Energies (ISSN 1996-1073, IF: 2.707).

Microgrids are defined as a cluster of loads, distributed energy resources, and storage devices, which are receiving worldwide attention owing to the increasing rate of consumption of nuclear and fossil fuels and the community demand for reducing pollutant emission in electricity generation fields.

The control functional requirements of a microgrid are: 1) regulation of voltage and frequency within limits, 2) active and reactive power balance and proper communication among resources, 3) seamless transition between grid-connected and islanded modes of operation, 4) economic dispatch of the resources, and 5) power flow control among microgrid components. Although many schemes and approaches have been proposed for each of the mentioned functions, possible faults and failures in any of the components of microgrids can severely affect the performance, applicability, optimality, and robustness of the proposed schemes, such that they are no longer suitable or even feasible/admissible. This means that the control schemes must be adapted appropriately to treat faults and failures in the components of microgrids.

This Special Issue aims at presenting the latest developments, trends, research solutions, and applications of fault-tolerant control to engineering problems in implementation and utilization of microgrids. We invite researchers to contribute original research articles as well as review articles that will stimulate continuing efforts to improve the current state-of-the-art in the aforementioned fields.

Energies 2020, 13(21), 5625; https://doi.org/10.3390/en13215625 - 27 Oct 2020

Control of AC/DC pulse-width modulation (PWM) power electronic converter, referred to as “AC/DC PWM converter”, is vital to the efficient regulation of power flow between AC and DC parts of a hybrid microgrid. Given the importance of such converters in AC/DC microgrids, this paper investigates the design of fault-tolerant control for AC/DC PWM converters in the presence of microgrid faults. In particular, two novel fault-tolerant schemes based on fuzzy logic and model predictive control are proposed and implemented in an advanced hybrid microgrid benchmark in MATLAB/Simulink environment. The considered hybrid microgrid consists of dynamic loads and distributed energy resources including solar photovoltaic arrays, wind turbines, and battery energy storage systems. The proposed schemes especially target the fault effects due to common power-loss malfunctions in solar photovoltaic arrays in the presence of microgrid uncertainties and disturbances. The effectiveness of proposed fault-tolerant control schemes is demonstrated and compared under realistic fault scenarios in the hybrid microgrid benchmark. Full article

In recent years, photovoltaic (PV) systems have emerged as economical solutions for irrigation systems in rural areas. However, they are characterized by low voltage output and less reliable configurations. To address this issue in this paper, a promising inverter configuration called Impedance (Z)-source inverter (ZSI) is designed and implemented to obtain high voltage output with single-stage power conversion, particularly suitable for irrigation application. An improved and efficient modulation scheme and design specifications of the network parameters are derived. Additionally, a suitable fault-tolerant strategy is developed and implemented to improve reliability and efficiency. It incorporates an additional redundant leg with an improved control strategy to facilitate the fault-tolerant operation. The proposed fault-tolerant circuit is designed to handle switch failures of the inverter modules due to the open-circuit and short-circuit faults. The relevant simulation and experimental results under normal, faulty and post-fault operation are presented. The post-fault operation characteristics are identical to the normal operation. The motor performance characteristics such as load current, torque, harmonic spectrum, and efficiency are thoroughly analysed to prove the suitability of the proposed system for irrigation applications. This study provides an efficient and economical solution for rural irrigation utilized in developing countries, for example, India. Full article

This paper provides an overview of islanding fault detection in microgrids. Islanding fault is a condition in which the microgrid gets disconnected from the microgrid unintentionally due to any fault in the utility grid. This paper surveys the extensive literature concerning the development of islanding fault detection techniques which can be classified into remote and local techniques, where the local techniques can be further classified as passive, active, and hybrid. Various detection methods in each class are studied, and advantages and disadvantages of each method are discussed. A comprehensive list of references is used to conduct this survey, and opportunities and directions for future research are highlighted. Full article
