The growing demand of light weight technology, cabin comfort, and better emission control and stability of the vehicles led to the increasing concern towards air magnetic suspension systems. Due to the high nonlinearity in the modeling process of such kind of systems, the stabilizing of magnetic levitation has been considered as a challenging task for many researchers in control engineering sector. This paper illustrates the calculating of all stabilizing PID controller gains for ED-4810 magnetic levitation system benchmark (Maglev) in the presence of uncertain parameters. Firstly, the linearized model of the uncertain plant is derived where the resultant characteristic polynomial is shown to be an unstable affine structure using Zero Exclusion Theorem and singular frequencies technique. Then all PID parameters values are demonstrated to establish robust stability using parameter space approach. The effectiveness of the proposed graphical method has been proved through simulation to achieve robust stability for magnetic levitation system.

In recent years, fault detection in electrical power systems has attracted substantial attention from both research communities and industry. Although many fault detection methods and their modifications have been developed during the past decade, it remained very challenging in real applications. Moreover, one of the most important parts of designing a fault detection system is reliable data for training and testing which is rare. Accordingly, this paper proposes an anomaly-based technique for fault detection in electrical power systems. Furthermore, a One-Class Support Vector Machine (SVM) model and a Principal Component Analysis (PCA)based model are utilized to accomplish the desired task. The used models are trained and tested on VSB (Technical University of Ostrava) Power Line Fault Detection dataset which is a large amount of real-time waveform data recorded by their meter on Kaggle. Finally, performance and Receiver Operating Characteristic (ROC) curves analyses of our results are exploited to verify the effectiveness of the proposed technique in the fault detection problem.

The usage of the Photovoltaic (PV) power systems has been increased dramatically, due to the abundant of the solar irradiation, and the government incentives everywhere. In most of the developed countries, the standards for connecting the PV systems to the grid has been set and is already applied. The incentives and regulations that supports PV systems are increasing day by day in Turkey. Because of this regulations more and more PV systems are connecting to the grid. Such high penetration of the PV systems in the distribution network leads to voltage disturbances. This paper studies the causes and effects of the voltage problem and proposes the best solutions to; mitigate the voltage disturbances and increase the distribution network stability.

With the significant increase in energy demand, there has been a trend toward using renewable energy sources. Solar energy as a type of renewable energy is the most abundant renewable energy available. To convert solar energy to electrical energy, a photovoltaic (PV) module is used. This paper focuses on PV module performance and its associated production losses. The methodology followed in this study was to use PVsyst software to compare the performance of different manufacturers PV modules under the same load profile and weather conditions. The comparison was made in terms of the efficiency and losses of some PV modules available in the local markets of Gaza Strip - Palestine. The selected PV modules for the performance comparison had the following brand names: Canadian Solar Inc., Trina Solar, GCL, JA Solar, and Suntech. The modules’ efficiencies were 16.19%, 16.12%, 15.91%, 16.21%, and 16.31% respectively. The results showed that the total losses of the modules were 13.77%, 13.24%, 12.55%, 13.36%, and 13.35% respectively.

Fault Tolerant Control Systems (FTCS) have become an important area of research for improving safety, reliability and efficiency of modern control systems. Generally, FTCS technique can be active or passive control. In this paper, the Fault Detection and Diagnosis (FDD) which belongs to the active control branch is used in order to detect faults that may occur in speed hall sensors of Brushless DC Motors (BLDC). The FDD methodologies, which depend on the process and the type of data available can be divided into two approaches; Model-based methods and data-based methods. Here, the proposed method focuses on the investigation of the use of Luenberger observer technique which belongs to the model-based approach. This observer depends on the residual signal which is used as a fault indicator in the overall system and represents the difference between the measured speed signal from the plant and the estimated speed signal. BLDC motor is selected as a benchmark for testing the proposed method due to the increasing demand for this type of motors especially in the renewable energy sector as in electrical vehicles, solar system, and new water pumping systems. The effectiveness of the proposed method is proved using MATLAB simulations and the results illustrate clearly the detection of faults as expected with high performance response.

In this paper, technical, economic and environmental impacts of utilizing useful Municipal Solid Waste (MSW) in the Gaza Strip for energy generation via Waste to Energy (W2E) steam generator as part of a Combined Heat and Power (CHP) plant are discussed. Being a good biogenic resource with high energy content, the paper also presents a practical solution for MSW treatment featuring a conceptual architectural design of a management plant to be located at Sofa landfill site considering MSW reduction, reuse, recycling and recovery (4Rs). Based on an assumed amount of MSW production of 190kton/year used for electricity generation, it was estimated that the required W2E steam unit size is 15MW. The amount of energy generated from this W2E unit is estimated to be 120GWh/year. Additionally, the reduced amount of Green House Gases (GHG) especially Carbon dioxide (CO2) emissions is estimated to be in the range of 88kton per year. Approximation of the capital cost of the W2E unit is evaluated at about 2900USD/kW. The Levelized Cost of Energy (LCOE) for the project is calculated to be about 0.05$/kWh. The capital cost retrieval period from energy sales is estimated to be in the range of 2-3 years.

The Gaza Governorate Electricity Distribution Company (GEDCO) is an economic service company operating with a special financial liability and owned by the Palestinian National Authority and local authorities.The unpaid bills are one of the company's biggest operating obstacles that obstructs money processing. The ever-increasing number of unpaid invoices has caused constant problems with the company's cash flow.In this paper, Data mining techniques and neural networks techniques were implemented over the data warehouses of GEDCO. Decision tree machine learning algorithm is used to classify the customers according to their commitment to payment, as well as to extract the categories for each class of customers. The neural networks are used to train the machine to extract a threshold for consumption and amperes. The threshold extracted for each subscriber according to his history of consumption and payment, to help him stay committed to payment.The results concluded that consumption should not exceed some value, based on the address of the subscribers, the number of amperes and the history of payment.The study that will be recommended to GEDCO, should improve their data warehouses to include more features and categories of their databases especially the subscribers’ occupations and level of income.

The side effects of producing electrical energy by the traditional ways that depend on fossil fuels are increased due to the rapidly rising energy demand in global. In recent decades, attention has shifted to integrating renewable energy systems (RES) to the power systems to reduce environmental side effects. However, this type of integration makes the power system control more complicated due to the volatile and variable nature of the RESs. Moreover, the topological changes of the power systems with the addition of RESs can negatively affect power system stability. Low-frequency oscillation is considered as one of the major concerns in the area of power system stability. This paper aims to investigate the impact of high penetration of RESs with different cases to the power systems. The considered RESs in this work are wind turbine and photovoltaic solar systems. These RESs are installed to 2-area Kundur power system to investigate the effects on low-frequency oscillations such as local and inter-area oscillations.

This paper introduces a 420-liter freezer powered by a PV solar system that works without spare batteries. Hence, it provides a green solution for stand-alone applications in remote areas and in places with electricity shortage. To this end, an AC compressor is replaced with a DC compressor to run by the PV panels using a controller that can allow for easy start-up, maximum power tracking, and power management for the system. The designed prototype enabled the freezer to run with attested operation. There are no issues concerning the compressor starting if the speeds is lowered. The system can remain operational even during low solar irradiance days. In addition, an optimum utilization of the photovoltaic energy can be accomplished.
