―Distributed generators (DG) have serious impacts on Directional overcurrent relays (DORs)-based protection system. Miscoordinated operation of DORs and escalated electromagnetic stresses on equipment are major concerns. Topology variation of the power network adds complexity to the problem. This paper proposes a simultaneous resetting-fault current limiters (FCLs) approach to sustain DORs' coordination in a reconfigurable network at minimum cost. A multi-objective constrained optimization problem is formulated. It is solved by the particle swarm optimization technique to obtain the optimal FCLs sizes and the updated setting parameters of few selected DORs. The approach is applied to IEEE 30-bus system. It efficiently restores DORs coordination and eliminates extra stresses on components.

The presence of the DG units influences the accuracy of the conventional fault detection and fault location methods. In this paper, a new approach to classify and accurately identify the fault location was presented. contrary to the traditional artificial intelligent methods which handle each signal separately, all the measured voltages and currents are converted to digital images. Accordingly, all the signals measured are processed simultaneously using a convolution neural network (CNN) to get more precise results. The Matlab Simulink, python programming, and google colab have been used to design a trained and validated CNN. Both of the faulty line and the type of fault have been precisely identified with insignificant errors not exciting 0.001 km. the CNN contains 1051885 trainable neurons.

this research deals with the optimal power flow (OPF) problem from the uncertainty perspective which arises due to the high penetration levels of renewable energy sources (RESs) in recent years. In this work, RESs are represented by wind and solar PV generators and their uncertain outputs are modeled by weibull and lognormal probability density functions (PDFs), respectively. From economic point of view, the uncertain output of wind and solar power is translated into the total power cost in form of reserve or penalty cost based on the situation of their output. The IEEE-30 bus and 57 bus power systems are adjusted to involve wind and solar PV generators. Gradient based optimization (GBO) algorithm is employed for solving the OPF problem in these circumstances. The obtained results have been compared with the results of other optimization algorithms presented in literature. GBO has achieved the minimum total power cost for both modified IEEE-30 and 57 bus power systems, 781.5504 $/h, and 20233.5012 $/h, respectively with low computation time and fast convergence of solution.

Theoretically, the output of the wind turbine might be estimated based the most known power equation that depends mainly in the wind speed. There are many issues appeared in the phase of the estimating and control while applying this equation due to ignoring many weather conditions. This paper introduces a multivariate estimation for the power curve of the wind turbine considering the weather conditions such as wind speed, air density, wind turbulence, and wind share. There variables are termed features, and a lot of measurement has been occurred to collect all possible data for these features, where measurements (system data) exceed 47,000 points. this data is proceeded mainly by three steps of the data sciences; exploratory data analysis (EDA), data processing, and building the model, using Python programming language, where it gives more flexibility more than the other languages. The power curve estimation is executed using different machine learning tools such as linear regression, polynomial regression, random forest regression, gradient boost (G Boost), and extreme gradient regression (XGBoost). A comparative study is introduced considering the R-square and the root mean square error. From the results, XGBoost learning tool provides the best performance in terms of root mean square error (RMSE). The RMSE value decreases to 6.404 while using the proposed algorithm compared to (6.631, 6.6721, and 9.072) attained through the alternative G Boost, forest random, and 4th-degree polynomial respectively.

One of the most important issues in improving of the efficiency of the photovoltaic system (PV) is finding the correct PV model. Determination of optimum parameters for PV models is vital to optimize and simulate PV systems based on the I-V characteristic, which is a nonlinear relationship Therefore, reaching the best PV model requires effective optimizers. This paper applies a new bio-inspired algorithm called Sooty Tern Optimization Algorithm (STOA) to obtain values of unknown parameters of various types of solar cells. The results of the experiment showed that, compared to other optimization algorithms, the used algorithm can obtain more accurate values of the estimated parameters.

In standalone or grid-connected PV systems, maximum power point tracking (MPPT) methods are essential since they control DC boost converter's duty cycles, thereby extracts the maximum power possible from such systems. Moreover, the power supplied by the PV array is a nonlinear function of its terminal voltage and current, which require a successful MPPT to pursue the maximum power point (MPP) regardless of operating conditions. This paper suggests a Transient Search Optimization (TSO) based on self-tuning fuzzy-Proportional Integral (PI) controller for MPP pursuing in the standalone PV system. The PI regulator is utilized to regulate to the PV voltage in relation to a reference voltage generated by TSO method in which its gain parameters are tuned using a fuzzy expert system. The simulation was done using MATLAB/SIMULINK for standard and different test conditions (STC and DTC). The obtained results reveal that the maximum power delivered to the load has been achieved with an efficiency of 100% at STC, while it was achieved concerning variable irradiation at DTC

In the electrical power system, the detection of power quality disturbances (PQDs) is a critical mission. In this paper, two-step methodology is used to solve PQDs detection; features extraction and classification. The features extraction step uses wavelet time scattering and the classification step uses the long short-term memory (LSTM) techniques. To assess the efficacy of the proposed approach, various simple PQ disturbances such as sag, swell, harmonics, and interruption, as well as complicated power quality events such as sag with harmonics and swell with harmonics, are produced using the MATLAB programming framework. A comparison using several methodologies is provided. The results demonstrate that wavelet scattering with LSTM can decrease classification computation complexity. Furthermore, it may significantly shorten classification time while assuring classification accuracy better than different approaches.

Electric vehicles (EVs) are attractive nowadays by industry and researchers to reduce emissions. The type of inverter is one of the solutions used to improve the EVs performance and efficiency. Therefore, this study presents a cascaded H-bridge multilevel inverter (CHB MLI) of seven levels for EV drive systems where batteries provide isolated DC sources. Moreover, advantages such as higher efficiency, better waveform quality, and higher power density can be obtained. Thanks to its high-power density and compact size advantages, the permeant magnet synchronous motor (PMSM) is used. Further, field-oriented control (FOC) is used in this paper to control the rotating speed of the PMSM. The performance of the overall drive system is examined through simulation results using the parameter of the actual 12kW PMSM. Extensive simulation results have proved that the proposed CHB can lower THD compared to the conventional inverter.

This paper aims to measure the impact of the climatic conditions, the oil thermal parameters, and the effect of the on-grid photovoltaic (PV) system on the transformer thermal performance for two different regional climatic conditions. Then, it's aimed to enhance the thermal performance by inserting an on-grid PV system. The climatic conditions have a major role in measuring the transformer's loading ability. Loading ability has a thermal limit, which is described as the winding hottest spot temperature (HST) as well as top of oil temperature (TOT). This loading ability was governed by the load profile and the environment's temperature; if they exceeded the limit, the transformer would deteriorate. So, to tackle this issue, climatic conditions are modeled on the principle of daily ambient temperature for mineral oil and oil natural air natural (ON AN) cooling type transformers. This paper concludes that using a PV system in parallel with the transformer to supply the same loads will improve the transformer's thermal performance by 22%.

A simplified dual-output boosting inverter topology (DOBI) is proposed in this study. It can be used to supply two independent single-phase loads from a low voltage DC-power supply with fewer active and passive components. The output voltages can be at common frequency (CF) mode or different frequencies (DF) mode of operations. The DOBI topology uses a single inductor and capacitor to control boosting and inversion operations. Compared to the traditional dual output inverter, the proposed topology in this paper (DOBI) reduces the active switches by 25%, while compared to the basic Z-source-based dual output inverter, it reduces the passive elements by 50%. The main drawback of this topology is the high-frequency current commutation problem of the forward diodes. A novel carrier-based pulse width modulation scheme to obtain sinusoidal output voltage with low input current ripples of the proposed topology is presented in this paper. Moreover, the presented topology's operating principles and mathematical analysis are introduced. Finally, a simulation study is presented to confirm the theoretical study.
