The high penetration of renewable energy resources in the distribution systems (DS), i.e., photovoltaic (PV) and wind systems, affects the system voltage profiles and causes severe violation problems. Therefore, the PVs output powers are curtailed in specific feeder nodes to mitigate the DS overvoltage problems, which causes unfair profit distribution among prosumers and decreases the hosting capacity of the PVs. This paper proposes a novel approach for optimizing the output powers of the PV sources in the DS. The optimal proposed approach aims to maximize the power generation of the PV prosumers while enhancing the network voltage profiles. First, an optimal power flow technique is carried out to compute active and reactive PV power's shadow prices to mitigate voltage violations. Then dynamic pricing is carried out online for the PV powers in DS using a multi-agent system. Finally, the performance of the proposed approach is identified through its application to the 33 and 5-bus test feeders. The results show an excellent performance for the proposed method in mitigating overvoltage problems and minimizing the PV power's curtailment.

This paper presents performance analysis of a novel design of permanent magnet (PM) biased fault current limiter used for high voltage direct current (HVDC) systems using COMSOL Multiphysics package. This cost-effective design overcomes many drawbacks of using PM in fault current limiters and enhances the performances. Results reveal that in comparison to the conventional/rectangular (letters: CI) core configuration (having the same volume of soft magnet, PM, and cross-sectional area of the DC coil), the new delta-shaped design shows an increased capability of fault current clipping ratio by ~34%, slowing of current slope (steepness) to ~65.8, and the peak value of induced transient overvoltage at the instant of fault clearing to 82.6%. In the novel design, it is found that increasing the number of turns and/or the PM height play a crucial role in enhancing the performance in terms of increasing the fault current clipping ratio, decreasing of current slope (steepness), and with a slight increase in the peak value of induced transient overvoltage. Finally, the fault duration, which is determined by the circuit breaker technology, governs the dynamic performance of the fault current limiter. The shorter the fault duration, the higher is current clipping ratio, and the lower is the transient induced overvoltage across the fault current limiter, without any effect on the current steepness.

The main direction these days is to use renewable energy to cover the power demand instead of fossil fuels. There are many reasons to make renewable energy resources be used than the fossil fuels, such as depletion of fuels and the need to use clean energy. The wind energy conversion system (WECS) is the most beneficial renewable energy resource. The significant advantage of WECS is that wind power is cost-effective, environment friendly, domestic installation, and sustainable. So challenging endeavor is exerted to enhance the WECS behavior. This paper reviews the different methods to improve the performance of the WECS based permanent magnet synchronous generator (PMSG). The performance enhancement of the WECS is represented in smoothing and maximizing the generated power and controlling the output voltage. The main control methods will be illustrated in this work, such as the various types of control topologies and the different optimization methods used. The advantages and drawbacks of each class will be discussed in this work.

The major malfunction of Permanent Magnet Synchronous Motor (PMSM) in Electric Vehicle (EV) applications is an open-phase defect, which degrades motor efficiency and increases losses due to unbalanced phase currents. Traditional Fault-Tolerant Control (FTC) techniques, on the other hand, could suffer from the monitoring problems of sinusoidal-shaped current references. In this study, a proposed fault-tolerant approach for open-phase during the driving cycle and starting of the PMSM is suggested, which differs from earlier fault-tolerant techniques by suggesting a proposed compensating transformation matrix for current and voltage references in the d-q rotating reference frame will be translated to the phase current and voltage references of the two healthy remaining phases. The proposed setup enables the EV to be operated under open-phase fault-tolerant (OPFT) with simple controller and high performance. Furthermore, since the proposed system depends on a four-leg inverter, it has a higher fault-tolerance capability than the three-phase Voltage Source Inverter (VSI) technique, to also compensate the possibility of loss of any VSI leg, but for sure with additional cost of the overall drive system. Eventually, the simulation output results supported the suggested fault-tolerant approach under Field-Oriented Control (FOC) for different modes of operations.

This paper proposes a Snake optimizer (SO) for cooperative Energy Management (EM) for Multi-Microgrid (MMG) with incorporating the Demand Response (DR). The newly-developed SO algorithm is used to determine the main objective of the MMG operator, which is the reduction of the operating cost. The SO is inspired by the snakes' mating behavior. The Independence performance index (IPI) is employed to reduce power transactions with the main grid. The proposed SO technique is compared with the conventional PSO technique; the simulation results demonstrate the efficacy of the proposed SO in solving the EM problem in MMG by reducing the operational cost and enhancing the MMG Independence in both cases, with the DR program and without DR. The proposed technique is tested in two different cases; the IPI using the proposed SO is about 85% and 92 % in Case I and Case II, respectively, while in the case of PSO, IPI in the two cases is 75% and 86%, respectively.

Many utilities have developed Transactive Energy (TE) market models. The TE market models offer small energy producers a framework to compete and gain more value from participating in the market. The utility also gains benefits from the TE market models. On the other hand, the utility is financially affected by the TE model in the form of sales reduction, forcing the grid to raise its tariffs and hence obtain fewer sales. Eventually, the grid may experience a death spiral. This paper reviews the different TE market model architectures, trading models, and clearing mechanisms. The paper also shows the possible impact of the market models on the utility with examples of utilities that experienced the death spiral and the corrective actions taken to face it. The paper provides a taxonomy for publications considering TE market models in the past three years.

Distribued Generations (DG) have economic, financial, and environmental benefits. DG reduces power losses in the distribution system but has a negative impact on the protection devices. In this article, the IEEE 33 bus system will be used and tested by adding up to three DG units using MATLAB/SIMULINK software. the optimization techniques that will be used are Grey Wolf Optimizer, Whale Optimization Algorithm, Genetic Algorithm, and Coronavirus Herd Immunity or COVID-19 optimization techniques to select the optimal site and size of the DG units based on the lowest pay-back period considering the voltage limits and power losses. The paper proposes a modified mutation operator for COVID-19 based on Gaussian and Cauchy mutations to have better performance and lower variance. The proposed algorithm is compared with the other optimization techniques. The proposed algorithm achieved better results, which proved to have competitive performance with state-of-the-art evolutionary algorithms.

This paper presents a smart management strategy for detecting, classifying, and locating open conductor faults in distribution systems. Different fault cases are considered even with a falling conductor from the source or the load side. The proposed method depends on installing smart agents at the beginning of each line. It is based on monitoring the fundamental currents and the zero-sequence component. For validation, the IEEE 33 distribution system is utilized via a detailed modeling with MATLAB/Simulink. Simulation tests corroborate the efficacy of the proposed technique for detecting, classifying, and locating all different patterns of open conductor faults.

This research work presents an accurate sensorless temperature monitoring for the commercial induction motor (IM) operated by soft starters (SSs). This technique is relying on calculating stator winding temperature (SWT) of the IM. The methodology is to inject or translate a DC signal into the motor at its normal operation without interrupting the motor running. The research work employs the artificial neural network (ANN) techniques in the asynchronous thermal monitoring scheme for supplying efficient and active temperature calculation of the stator winding, also for decreasing the estimation error. The value of Stator Winding Resistance (SWR) and SWT that computed from signal injection is processed by the ANN with other parameters such the current of stator winding to obtain an accurate value of SWT. A comparison between the results of the proposed ANN scheme and other techniques is performed and the obtained results are inventively.

Presently, distribution companies are concerned with the penalty applications in energy tariff to control harmonic distortion levels in distribution systems. It's common to consider this for industrial and commercial customers. But, nowadays the usage of modern electronic equipment in residential section is increasing and people are going to do their jobs at home, which mean more distortion in single phase systems. So, in the early future companies will pay more attention for requesting residential customers to provide better power quality. This paper proposes a distinct rate structure to regulate the harmonic distortion in single phase systems, which is applicable for residential loads. The idea is to evaluate the responsibility of harmonic distortion at the Point of Common Coupling (PCC) between utility and customer for each harmonic order of power frequency. By finding the utility and customer harmonic contributions, it is possible to achieve fairer cost sharing through the proposed rate structure. This method has been verified through a simplified case study mentioned in the IEEE Std. 1459-2000.
