Neural Network-Based Fault Distance Estimation for Multi-Terminal DC Microgrids

Fault distance estimation in DC microgrids is a critical issue due to the growing adoption of DC-based distribution systems. Current methods face limitations like sensitivity to system parameters and high-resistance fault detection, necessitating improved accuracy. This study proposes a neural network approach to accurately locate fault distances in multi-terminal DC microgrids. Three different structures based on backpropagation algorithms are developed and trained to estimate fault distances with high precision. These structures can handle various fault scenarios, including different fault resistances and the presence of noise. Two of the structures can predict fault distances from one side locally, achieving low error rates of 0.3% for the source side and 0.6% for the load side. The third structure incorporates input variables from both sides, resulting in even more accurate predictions with an error rate of less than 0.15% for both terminals. A comparative analysis was performed to evaluate the proposed fault distance estimation structures in terms of error percentage, cost, fault resistance, and reliance on communication systems. The results demonstrated the superiority of the proposed structures in all aspects, emphasizing their effectiveness in improving the performance of the protection system.

PLPR-Based Predictive Control for LCL-Filtered Voltage Source Inverters

The model predictive control (MPC) is sensitive to parameter variations in LCL -filtered voltage source inverters (VSIs). To improve the robustness of the MPC, this article proposes a parameter less prediction and reference-based predictive control (PLPR-PC) for LCL -filtered VSIs, where the proposed PLPR-PC not only obtains the parameter less predictions by measuring and updating all current-voltage gradients, but also obtains the parameter less references by using the phase differences between measured currents and voltages. The proposed PLPR-PC effectively eliminates parametric effects on both prediction and reference calculations and thereby improve the robustness of grid current for LCL -filtered VSIs under parameter variations. The 30-kW simulation and experimental prototype are built up to verify the feasibility and performance of proposed PLPR-PC.

Analysis of a coaxial magnetic gear optimally designed using Particle Swarm Optimization

One important key to improve the efficiency of adjustable speed drives is using magnetic gears due to their advantages in comparison to their mechanical counterparts. This paper introduces an analysis study for a magnetic gear optimally designed using the particle swarm optimization algorithm (PSO). Moreover, the results of the PSO-based design are compared with the results of another optimization design process based on a genetic algorithm for the same design parameters and constraints. The proposed magnetic gear topology to be optimized is a radially magnetized coaxial configuration with a surface-mounted permanent magnet array. The gear ratio of the proposed magnetic gear is chosen to be 3.5 while the cogging factor sets at one. Using PSO in magnetic gear design aims to facilitate torque transmission in the maximum possible value while minimizing torque ripples. The performance analysis of torque results and flux density waveforms of the proposed magnetic gear is conducted through the use of Finite Element Analysis (FEA). The results analysis of the proposed magnetic gear shows superior torque production with minimal ripples and customized dimensions thanks to the PSO-based design.

Novel Zonal Fault Detection Scheme For DC Wind Farm Via Disposition of Surge Arresters In Multipurpose Grounding System

Recently, a prospective new concept of onshore DC wind farms (DCWFs) employing a large-scale grounding system incorporating sheath-connected protective surge devices (PSDs) to ensure protection against probable surges, keep safety of operators, and increase efficacious energy conversion is suggested. This concept involves connecting ungrounded terminal of single-core cable sheath via PSD to conform manufacturers recommendations to avoid thermal stresses. This paper proposes a novel zonal fault detection scheme for DCWF using the installed PSDs as fault location indicators. The proposed scheme relies on distinctive post-fault behavior of PSDs by processing the respective voltages and/or currents captured at each junction by intelligent devices (IDs) at each terminal. PSDs average currents and/or polarities of average voltages at each terminal over 0.5 ms moving window are computed for …

Induced Electromagnetic Fields on Underground Cable Due to Lightning-Struck Wind Tower

In regions having high activity of lightning flashes, it is important to investigate the lightning-induced electromagnetic (EM) transients affecting buried cables, particularly if such buried conductors are extending close to grounded towers, such as wind towers. In this article, the impact of the grounded wind tower, ground conductivity and permittivity, depth of the cable, and its position from the return stroke on the lightning-induced EM fields on the cable sheath are investigated. In addition, the lightning-induced EM fields on the cable sheath are also calculated with the presence of bare-underground wire above the cable as a protection against lightning strikes. The 3-D finite difference time domain method with nonuniform grid technique is implemented for this study. From the results, it is shown that the presence of wind tower increases the magnitude of lightning-induced EM fields on the cable sheath, particularly for …

Sensorless robust flatness-based control with nonlinear observer for non-ideal parallel DC–AC inverters

Parallel operation of multiple AC/DC inverters is favorable in hybrid AC/DC microgrids to avert consecutive conversion stages and increase the system’s efficacy. Yet, several emerging technical challenges impede the expansion of such layout such as the circulating currents, sensitiveness to the input voltage disturbances, load variations and complexity of the control structures caused by using several required measurements. This paper proposes a one-loop sensorless controller which is based on the flatness technique for a non-isolated power supply consisting of n-parallel inverters. The proposed control scheme primarily relies on employing a nonlinear online observer to estimate the line inductor currents and the dc link voltage via information from the input voltage, output voltage, and load conditions to avoid using excessive sensors. In this way, the system reliability is improved by reducing burdens of the …

Adaptive synergistic control strategy for a hybrid AC/DC microgrid during normal operation and contingencies

This paper proposes an adaptive synergistic control strategy for a hybrid AC/DC microgrid to overcome its vulnerability to notable grid impedance variation provoked by load changes. Microgrid employs an internal DC link incorporating hybrid renewable resources represented by wind turbine generator, photovoltaic arrays and hybrid energy storage system. The latter comprises supercapacitor stacks for fast compensation and a hydrogen management scheme for long-term energy storage to counteract renewable resources indeterminacy. The internal DC link is attached to the AC side via a grid-side converter to constantly realize bus voltage and frequency constancy. The central premise of the proposed strategy during normal conditions is to meet load obligation via proper sharing of demanded power among hybrid resources and storage systems, optimize operation schedule of hydrogen management scheme to …

Computation of lightning-induced voltages considering ground impedance of multi-conductor line for lossy dispersive soil

Soil conductivity and permittivity have a substantial influence on lightning-electromagnetic transients in power system. In this paper, lightning-induced voltages are computed on a multi-conductor overhead line due to nearby first and subsequent return strokes. Besides, this study considers the longitudinal complex inductance of the line due to the penetration depth of electromagnetic fields through finitely conducting ground as well as the frequency dependent soil parameters using the finite-difference time-domain method. Various case studies in light of variations of return stroke velocity, line height, and soil conductivity are explored for thoughtful investigations. The obtained results reveal that the influence of this complex inductance on peak values of lightning induced voltages changes with varying the return stroke velocity. Also, the frequency dependence of soil parameters markedly impacts the computed …

Local current-based method for fault identification and location on series capacitor-compensated transmission line with different configurations

This paper proposes a new efficient method for fault detection, faulty phase selection, and fault point identification on series capacitor-compensated transmission line. The method is based on sensing only the three phase current at the relay site. A reverse synchronous reference frame (RSRF) approach is proposed for fast fault detection and classification. Then, an analytical algorithm based on symmetrical components theory is presented for accurate estimation of fault location. Three possible arrangements of the series capacitor bank (SCB) on the line are analyzed. The SCB and the associated protective metal oxide surge arrestor (MOV) are modeled thoroughly to characterize its behavior during fault. In addition to its simplicity and practicality, the proposed scheme is equipped with decaying DC offset removal technique that allows fast extraction of the current phasors within one fundamental cycle. The proposed …

Investigation of novel DC wind farm layout during continuous operation and lightning strikes

This paper proposes a novel layout for a grid-connected DC wind farm (DCWF) and investigates the performance under continuous operation and direct lightning strikes particularly for high soil resistivity. The DCWF employs internal dc grid that supplies generated power to the host AC utility through high voltage direct current (HVDC) transmission link. The proposed layout ensures sustainability of power supply against potential interruptions of DCWFs either during normal conditions or lightning incidents to comply with grid codes regulations. During continuous operation, the proposed layout safeguards the entire DCWF cables against flow of return currents to avert derating of conductor ampacity. Besides, protects WT nacelle switchgear and entire interface converters against hazards of surge currents. Furthermore, an effective grounding system design is proposed to introduce a low impedance path for system …

Proposed controller and stability analysis for DFIG to suppress stator flux oscillations during autonomous operation

Doubly fed induction generator (DFIG) driven wind turbines experience poorly damped stator flux oscillations at frequencies around the fundamental, limited low voltage ride through capability and output power fluctuation. In this study, a proposed controller to mitigate stator flux oscillations of DFIG is proposed during autonomous operation mode. In addition, super‐capacitors based energy storage is integrated to manipulate wind speed vagaries and contribute to load demand. A 53rd‐order small‐signal analytical model and eigenvalues study is carried out to optimally determine control system parameters and pinpoint latent system dynamics and stability margins under various operation conditions. Also, a detailed non‐linear system is modelled and simulated in Matlab/Simulink environment to assure small‐signal model results. The results obtained confirm the accuracy of the analytical model and explore the …
