“…Based on the above about the function of the magnetic field, and comparing to the conventional methods of black powder removal, and also based on the abilities of computerized systems for monitoring and/or controlling functions [19][20][21][22][23][24][25][26][27][28][29][30][31][32], the presented method in this paper focuses on controlling the level, location, and polarity of the allocated magnetic field in order to remove the black powder from crude oil. On the other hand, due to adopting the electrical resistivity measuring for well logging development [33], a new design of resistivity sensor in presented in this study in order to sense the crude oil resistivity will be presented through which the proposed system's performance can be evaluated.…”

Black power represents the main difficulty faced by the oil flow in pipelines. The negative effect of this powder reaches to stop the oil flow due to clogging the pipelines, in addition to the damaging of the crude oil pumps. Many solutions have been proposed in literature based on chemical or physical processes. On the other side, applying the fixed magnetic field has been presented in separation and extraction process of metal impurities in water pipelines applications. From these facts, this paper proposes an alternative solution (idea, design, and methodology for future implementation) for the black power removing from oil pipelines. The proposed system works on firstly sensing the resistivity parameter in the crude oil as an indication about the oil status with respect to the quantity of the black powder particles, then works on monitoring and controlling the level, location, and polarity of the required magnetic field that to work on cracking particles cracking function that in order to facilitate the crude oil motion in the pipelines. In addition, the proposed solution presents a new design of electrical resistivity sensor as an important indication in terms of evaluating the proposed system performance

“…For off-grid solutions, solar energy is considered as one of the green renewable energy sources, this source is playing a major role to deliver the required electrical power for the isolated/moveable/individual/remote dwellings [1]- [2]. In terms of merits, solar energy source is characterized by the availability, the cheapness of the harvesting, the cleanliness and the easy harvesting through photovoltaic panels [3]- [4]. Whereas in terms of demerits, the effectiveness of the solar energy source is suffering from several factors such as the fluctuation in the irradiance and ambient temperature levels of the weather conditions, and weather dust.…”

The difficulties of the grid electricity supplying to certain locations like far, high lands, or countryside leads to concentrate on the solutions of the renewable photovoltaic stand-alone system supported by an efficient maximum power point tracker. In addition, the difficulties of the alternating current system which are represented by a complicated controller, system size, and high cost due to the necessity of involving an inverter, a high order filter and a step up or an insulation transformer. From this point of view, this paper presents a new solution of 10.8 kW PV system which combines between the high performance of the MPPT controller and the avoiding of the alternating parts by considering direct current home appliances. A study of loads' power requirements, PV matrix design of an isolated dwelling, a full electronic design of a DC-DC boost converter with a fast response MPPT controller based on an Artificial Neural Network (ANN) which is followed by Proportional Integral (PI) controller all are presented in this paper. The simulation results are collected through MATLAB/Simulink, and the system performance is evaluated and indicated the high effectiveness in terms of harvested power.

“…Immune algorithm (IA) [20] and genetic algorithms (GAs) [21] are examples. Moreover, the reduction of THD is also reflected on the improvement of conventional PWM, such as dual-level dual-phase carrier (DLDPC) PWM [22], staircase-PWM modulation [23] and confined band variable switching frequency PWM (CB-VSF PWM) [24]. It can be found that THD is not taken as the control objective directly among the methods mentioned above.…”

Inverters are commonly controlled to generate AC current and Total Harmonic Distortion (THD) is the core index in judging the control effect. In this paper, a THD oriented Finite Control Set Model Predictive Control (FCS MPC) scheme is proposed for the single-phase inverter, where a optimization problem is solved to obtain the switching law for realization. Different from the traditional cost function, which focuses on the instantaneous deviation of amplitude between predictive current and its reference, we redesign a cost function that is the linear combination of the current fundamental tracking error, instantaneous THD value and DC component in one fundamental cycle (for 50 Hz, it is 0.02 s). Iterative method is developed for rapid calculation of this cost function. By choosing a switching state from a FCS to minimize the cost function, a FCS MPC is finally constructed. Simulation results in Matlab/Simulink and experimental results on rapid control prototype platform show the effect of this method. Analyses illustrate that, by choosing suitable weight of the cost function, the performance of this THD oriented FCS MPC method is better than the traditional one.
