In this paper, a control technique is elaborated for a stand-alone induction generator (IG) driven by a wind turbine for use in rural areas. The generator is excited by a bank of capacitor. While the buildup of the voltage starts, there is a variation in the linkage flux of the IG, which lead to the variation of the magnetizing inductance due to saturation of the core. The main goal of this paper consists of regulating the DC bus of an AC/DC converter using a control strategy calling DPC or direct power control, this technique consists of choosing control vector from a switching table based on instantaneous active and reactive power error and the line voltage position.

Among all Concentrating Solar Power technologies available, the solar tower technology is one of the most interesting technology that attract researchers. This paper investigates the thermal performance of the central receiver using a numerical simulation, where the proposed solar power plant is based on the Brayton cycle with volumetric air receiver. The transient system simulation software (TRNSYS 16) was used to evaluate the performance of the solar tower plant. The system was carried out on different climatic conditions of the MENA region such as Bechar, Adrar (Algeria), Cairo (Egypt), Abu Dhabi (UAE), Tripoli (Libya), Tunisia (Tunis) and Baghdad (Iraq). The obtained results show that, for a volumetric receiver with aperture equal to 25m2, the temperature of the working fluid can reach 1080 °C during the plant operation which is considered high. In addition, the efficiency of the thermal receiver has been found around 88% due to the high operating temperature. The results of the analysis indicate that the higher solar intensity higher up the overall thermal efficiency.

In an era where plants based and healthy diets are more adopted by the consumers and where the environment-friendly processes are are prevailing, preservation of nutritious natural sprouts by a time and energy saving treatment prompted us to conduct this study. Optimization of the germination of common wheat and Kamut grains was first presented. Reduced imbibition times of 3 and 5 hours were obtained for wheat and Kamut grains respectively with less water consumption. Then an optimal germination duration of 7 days was determined for both grains by monitoring the lipids, proteins, vitamins B2, B6, E and $beta$-carotene contents during germination. Afterwards these sprouts were treated by Intensification of Vaporization by Decompression to the Vacuum (IVDV) and hot air dried to a water content of 4%. The effect of this treatment on the nutritional content of the sprouts and their drying kinetics were then studied. IVDV was proved to preserve the vitamins content of sprouts while saving around 8 hours of hot air drying.

The cost and efficiency of a photovoltaic (PV) system are related to the maximum power point tracking (MPPT) technique used, this has led to a continual development and improvement of their control systems. The most preponderant techniques usually require at least a couple of current and voltage sensors and a relatively complex control strategy. In order to reduce the overall cost and control difficulty, this paper presents a novel MPPT controller with reduced number of sensors through predictive control technique The proposed MPPT controller is based on a checking algorithm using one current sensor that senses only the load current and allows an instantaneous interaction between the power delivered by the PV and the power needed by load The developed technique has been incorporated into a PV model built in Matlab/Simulink adapted to the real characteristics of the PV array used in experiment. The simulation results proves the PV system efficiency and its enabling to optimize system performance under various predicted current. The algorithm has been implemented using FPGA card and the obtained results in the experiments validate the efficiency of the proposed controller algorithm.

Active distribution networks will meet new challenges in voltage and congestion control due to the high penetration levels of distributed generations (DG). Optimal voltage control techniques are mainly based on the relation between the network voltages and control variables (i.e. power injection). Thus, in this paper, a centralized real time scheme using a fast method for computing the sensitivity coefficients is presented to control congestion and voltage problems. The sensitivity coefficients of network voltages as well as the branch line currents are obtained via direct analytical derivation. A 11KV, 75-bus distribution system including several DGs is used to validate the proposed method. Simulation results show that the proposed method is able to maintain the network voltages and line currents within acceptable limits.

In this paper, the problem of controlling three-phase induction motors with unmeasurable states is tackled. To that end, a finite-time robust nonlinear current control is applied. The controller employed is the first order sliding mode with exponential reaching law variant. Moreover, in order to estimate some variables that are not measurable, such as the rotor current, a state observer based on Luenberger observer is implemented. Simulation results show a good tracking of the desired reference, given that there exist some dynamics which were not modeled and there are fast changes in the reference.

Microgrids (MG) are a new trend on electrical grids. Despite their dependence on intermittent renewable resources, they provide harmful greenhouse gas emissions to our environment and may present a long-term solution to meet future energy needs with sustainable energy resources (e.g. solar example, wind turbine). Initially, the MG adopted is a hybrid system with non-controllable sources as renewable sources, an energy storage system and controllable sources (e.g. diesel generator (DG), fuel cell (FC), micro turbine (MT)) to ensure MG reliability, transparency and efficiency. It’s also recommended to maintain the frequency as part of the quality of electrical energy affected and disturbed by the intermittence of sources and loads that cannot be controlled depending on conditions weather (for example, solar irradiation, wind speed, temperature) and human behavior (load). This article presents a study of the impact of the storage system and the effect of the uncertainties of the MG system and the frequency of noise recovery by applying a secondary control based on a PI control set by combined GATLBO. A simulated isolated MG is tested in scenarios to test the approach adopted to design the PI parameters in order to avoid frequency fluctuation in the different case studies.

This paper proposes a novel algorithm for maximum power point tracking (MPPT) in photovoltaic panel sourced boost converter. The novel MPPT tactic has a high convergence speed and zero oscillation around the MPP under steady state operation, and high tracking speed in response to rapid changing of irradiance. Furthermore, it improves the tracking accuracy, without increase the implementation complexity. The proposed technique has been simulated in Matlab/Simulink environment and compared with some other MPPT techniques, such as Perturbed and observed (P & O), Increment of Conductance (INC) and fuzzy logic (FLC).

The building must be characterized by a good architectural design, adequate construction materials and passive systems especially the ones adapted to local climate. There are many examples of systems and installations that stand as solutions, from passive techniques and local materials to secure ultimate indoor conditions as it is contended by with the Moroccan building code requirements, and thus tuning the energy use wisely. Therefore, dynamic simulation study was conducted to examine the annual thermal loads for heating and cooling for configurations of the studied building within the set points of NM ISO 7730 was conducted, this study carried out through a comparison of the established thermal loads prescribed by RTCM (Moroccan building code). Results shows a clear reduction of thermal loads performed by the building configurations which combines the three studied passive techniques. These passive components perform up to 63% reduction of the annual thermal load and shows a neat adherence to the performance-based requirements of RTCM.
