This work is focused on the control of a wind turbine system based on (PMSG). In order to enhance the efficiency of the wind turbine system, the maximum power point tracking (MPPT) control is applied to exploit the maximum power from the wind. The Fuzzy Logic controller (FLC) has been proposed and developed for the speed control. The simulation results show good performances of this control.]]>

Prediction]]>
At a time when the energy transition is inescapable and artificial intelligence is rapidly advancing in all directions, solar renewable energy output forecasting is becoming a popular concept, especially with the availability of large data sets and the critical requirement to forecast these energies, known to have a random nature. Therefore, the main goal of this study is to investigate and exploit artificial intelligence's revolutionary potential for the prediction of the electricity generated by solar photovoltaic panels. The main algorithms that will be studied in this article are cubist regression, random forest and support vector regression. This forecast is beneficial to both providers and consumers, since it will enable for more efficient use of solar renewable energy supplies, which intermittency makes their integration into the existing electrical networks a challenging task.]]>

Today, renewable energies have become one of the most important concerns of the countries of the world as a result of the negative effects we have reached on the environment from our use of fossil fuels and the resulting emissions of toxic gases. It is no secret that the fields of renewable energies are very diverse, including those derived from biomass. Researchers in this field seek to diversify bioenergy sources from ethanol, biodiesel, and fuels. Biogas. Accordingly, we conducted this study using date kernel oil as a new source for biofuel extraction, and the results were as follows: oil content of 4 to 5 percent, with a very high acid number of 8.9776, which imposes on us make a reaction of esterification and transesterification. Biodiesel has a 91 percent yield and its properties are close to recognized standards compared to previous studies.]]>

The paper concentrates on a comparison between two DC/DC converters topologies, the conventional Boost and the Multi Level Boost Converter (MLBC), for connecting into PV systems. Several performance criteria are included as part of this comparison process for both converters under varying climatic conditions (irradiation and/or temperature). The DC/DC converters' function is to serve as an interface between PV generator and load. We apply MPPT (Maximum Power Point Tracking) control with duty cycle adjustment using PWM technique for extracting the highest achievable output power from PV generator. The multilevel boost converter (MLBC), which is capable of monitoring and maintaining an equal voltage on all N output levels, along with controlling the input current. MATLAB/Simulink simulation results highlight the performance of the Multi-Level Boost Converter (MLBC) converter topology, to match the GPV voltage to the load.]]>

It is required to simulate the performance of a photovoltaic solar cell performance to enhance it. Simulation optimization has the benefit of being inexpensive and straightforward, and it allows us to identify the optimum parameters that contribute to the enhancement of the cell. An alternative ZnSe/CdS/CIGS/Si structure has been presented using a solar cell capacitance simulator (SCAPS-1D). This paper aims to increase device efficiency by improving the physical characteristics of the many layers involved in cell realisation. We also tried to investigate the variation of electrical characteristics such as Voc, Jsc, , and FF with the changes in material parameters, notably the absorber layer thickness (CIGS, p-Si) (CIGS, p-Si). On the other hand, the temperature dependency has been simulated to guide device manufacturers to attain higher efficiency in varied temperature circumstances. The calculation result shows that excellent performance can be reached by varying the parameters, and the highest efficiency (24,94 %) of the solar cell can be reached under certain conditions, where the thicknesses of ZnSe, CdS, CIGS, and Si are 0.2m, 0.09m, 1.4m, and 0.6m respectively and for the optimal value of temperature equal to 295K.]]>

Droop Control]]>
Energy Storage system]]>
Wind turbine]]>
Microgrid]]>
In recent decades, the development of renewable energy has accelerated significantly due to several factors such as changing energy needs, the problem of global warming, and the depletion of fossil fuels. Wind energy is one of the renewable generation sources that can be used to achieve the EU's 2030 targets at a lower cost. However, its intermittent and stochastic nature could significantly impact the reliability and stability of the electricity system. Therefore, there is a clear necessity to mitigate power fluctuations to make the most of wind energy. To fill this gap, this paper presents a centralized control strategy based on a droop controller and a storage-integrated controller for a grid-connected variable speed wind power system (permanent magnet synchronous generator) (PMSG) to manage and stabilize the power output during intermittency periods. The main objective is to provide a stable U/f when a fluctuation event occurs. A grid failure scenario was tested to see how the control system behaves in the event of an unexpected fluctuation and its role in the stability of the power system under varying wind speed and load conditions. The effectiveness of the proposed control method was tested using MATLAB/Simulink on a small power system. The simulation results demonstrate the control system’s performance in the stability of the U/f during grid interruption.]]>

control WT]]>
This work presents a control strategy for Wind Turbine (WT) power by using an algorithm of Indirect Maximum Power Control (IMPC). This algorithm is based on Tip Speed Ratio (TSR) approach, which is applied to control wind turbines. Indeed, the WT used in this study has a single mass brought back to the generator shaft. The main contribution of this study is to maximize the aerodynamic power delivered by the WT system. In fact, this maximization is carried out during partial load operation, without consideration of the disturbances caused by variations in the wind profile. In this context, the control strategy of the WT is performed by estimating the Wind Speed (WS) instead of using an anemometer. This estimation is handled by using an Adaptive Gain Sliding Mode Control (AG-SMC). For this control, the surface is chosen as an improved solution that carried out the adaptation for the sliding gain and the generator torque estimation. The results obtained in Matlab / Simulink software showed that the aerodynamic power maximum is achieved and the control algorithm IMPC is given a high efficiency in the WS estimation.]]>

This paper describes a two-dimensional computational fluid dynamics (CFD) model of flow with mass transfer to simulate a membrane separation system. The fluid domain comprises two reverse osmosis (RO) membranes and is fitted with different wavy inserts that act as turbulence promoters. Four types of insert designs were evaluated in terms of salt deposition on the membranes, permeate flux, axial pressure drop in the channel, and plots of the Sherwood number against the Power number. According to numerical simulations, under the operating conditions of this investigation, the proposed designs generate better results than commercial designs. The gain in pure water flux achieves up to 2%, and salt deposition on the membrane surface is reduced by ~5% than the commercial Zigzag spacer arrangement.]]>

Heating and ventilation in the building is essential to establish thermal comfort. The modern means invented to provide us with our heating and ventilation needs are generally expensive and represent sources of pollution. It is for this reason that there are several studies directed towards the research of renewable energies and non-polluting economic systems. The simulation of such a natural system at an almost low cost is the subject of our study in this work. In this work, a numerical study of passive heating and ventilation was made by natural convection in a room containing a heated vertical wall. In the case of heating, the system is closed and two openings are considered in the heated vertical wall allowing the re-circulation of the air in the room and therefore the heating of this latter. In the case of ventilation, the room is open to the outside through two inlet and outlet openings allowing the air circulation from the outside into the room and from the room into the outside which leads to ventilate the room. Numerical results with different mesh and Rayleigh number have been presented and their effects have been discussed.]]>
