In this paper, a new hybrid maximum power point tracking controller has been proposed. This one is composed of two control blocs, which are cascaded in series in order to follow the maximum power point. The first control bloc consists of the the Fuzzy Logic controller. This one is used to generate the reference voltage that corresponds to the maximum power point. While the second one is the robust sliding mode controller, which is used to track the voltage reference generated by the first controller bloc, by adjusting the duty cycle of the Boost converter. The proposed system is composed of the PV module (Type: KYOCERA KD240GX-LPB), of the Boost converter and the resistance of 55 Ω. The proposed hybrid controller has been compared with the P & O-SMC and INC-SMC techniques to prove its good tracking performances in term of speed and precision. In addition, this technique is tested to validate its ability to detect the environmental conditions changes.

This study examines the causal links between electricity production from renewable sources, CO2 emissions and economic growth in Morocco. In this regard, the study used Auto Regressive Distributed Lag (ARDL) bound testing approach and Toda Yamamoto causality test over time series data from the period 1990 to 2015. The results of the co-integration test reveal the existence of a short-and long-term equilibrium between the variables. Furthermore, in the short term, CO2 emissions, electricity production from renewable sources and the active population have a negative impact on GDP. Gross fixed capital formation also has a negative impact on economic growth for up to one year but becomes positive after two years.. In the long term, GDP is mainly caused by CO2 emissions, the labor force, and the production of electricity from renewable sources. These results support the growth hypothesis. GFCF does not directly influence economic growth in Morocco, but indirectly through electricity production to explain the dynamics of GDP.
本研究考察了摩洛哥可再生能源发电、二氧化碳排放和经济增长之间的因果关系。为此，本研究对1990 - 2015年的时间序列数据采用了Auto Regressive Distributed Lag (ARDL)绑定检验方法和Toda Yamamoto因果关系检验。协整检验的结果显示变量之间存在短期和长期均衡。此外，在短期内，二氧化碳排放、可再生能源发电和活跃人口对GDP产生负面影响。固定资本形成总额对经济增长也有最多一年的负面影响，但在两年后变为正影响。从长期来看，GDP主要是由二氧化碳排放、劳动力和可再生能源发电造成的。这些结果支持了增长假说。GFCF并不直接影响摩洛哥的经济增长，而是间接通过电力生产来解释GDP的动态。

Several works dealt with the control of the doubly fed induction generator (DFIG) integrated in a wind system. To reduce the problem complexity, the DFIG considered model is generally based on the assumption that the magnetic characteristic is linear. In coherence with this assumption, most DFIG control strategies involved rotor flux regulation around a fixed operation point (generally a nominal flux value). As a matter of fact, a constant flux reference, especially in wide range load and wind speed variations, doesn’t assure an optimal performance operation mode. Practically, without accounting for the nonlinearity of the machine magnetic characteristic, control strategies involving wide range flux reference variations cannot be reached.In this paper, based on a new DFIG model that accounts for the magnetic characteristic hysteresis and saturation, a new speed and flux optimal controller is developed. This regulator is designed using the backstepping technique. The performances of the proposed controller are formally analyzed using tools from the Lyapunov stability and averaging theory, and their supremacy with respect to standard control solutions is illustrated through simulations involving wide range variation of the wind speed.

The presented work in this paper tackles the control problem with a Sliding-Mode Controller of a double input single output (DISO) DC–DC power converter that combines the power from a wind generator and a solar PV panel to supply a constant power load. The design procedure of the SMC is clearly developed with the appropriate control theory. In fact the proposed regulator is modulated to overcome the intrinsic unsettled behavior of the DISO converter in both off and on states, and to provide a high degree of output DC bus voltage regulation. Simulation results of the DISO converter for its reactions to load and DC line regulations illustrate the effectiveness of the SMC and its robustness to control the integration of a hybrid power system including diverse kinds of energy sources.

Thermal insulation of building envelopes is one of the most efficient way to ensure passive thermal comfort and reduce the carbon footprint of the construction sector. Therefore, looking for innovative low-cost insulation materials represents a key challenge. This paper presents a development of a new enhanced cement-based building material using local by-products and describes its impact on the energy efficiency of residential buildings. An experimental study on the effect of adding plaster and Expanded Polystyrene (EPS) with different volume fraction on the thermal properties of cement is presented. The thermal transport properties of the developed mixtures are investigated using the Hot Disk method. The results obtained showed that the addition of 5 vol.% and 40 vol.% of plaster and EPS respectively decreases the thermal conductivity of cement by nearly 40%, which highlights the importance of the proposed mixture for enhancing the thermal resistance of the building compounds. For comparison purposes a dynamic thermal simulation was carried out for a typical Moroccan house located in Oujda city, Morocco. The numerical results show that up to 40% of cooling and 31% of heating loads required to reach thermal comfort could be reduced, if the proposed material substitutes the conventional one.

Extension of grid for remote rural electrification has been a challenge due to multiple factors including scattered population, poor road and communication connectivity and difficult terrain. Moreover, since their livelihoods are generally dependent upon small-scale farming, extension of grid for house lighting, basic necessity is uneconomical for the power supply agencies. To meet the need of such remote areas generating power locally through the available natural resources is considered more feasible. Hence, focus on Photovoltaic (PV) system, small hydropower system and other renewable resources are emerging to bridge the gap. In order to improve the efficiency and reliability of the power generation, protection of the system from different fault is of critical importance. PV systems consist of power generation in DC and AC stage and both suffer from different kinds of faults that is not easily detected since it is exposed to many kinds of fault that could be environmental or electrical. A conventional fault protection method uses fuses or circuit breakers in series with PV components. Some faults in PV arrays remain undetected due to its current-limiting property of the fuses and non-linear output characteristics of PV arrays. Therefore, this paper aims to develop a fault analysis in solar photovoltaic (SPV) arrays. In this paper literature on various fault detection algorithm and techniques have been discuss, PV array has been modelled and simulated for fault detection such as line to line (L-L), line to ground (L-G), open circuit and partial shading and their output characteristic has been compare.

The Photovoltaic (PV) plants combined with energy storage systems are one of the promising solutions of full utilization of renewable energies. These main elements can be used to implement a dc nanogrid (dc-NG) which is a power distribution system for a single house/small building, with the ability to connect or disconnect from other power grids. Moreover, the switching dc-dc converters are widely used to interface the dc output of renewable energy resources with power distribution systems in order to facilitate the use of energy at the customer side in a nanogrid. In the case of residential PV applications, the high conversion ratio is usually required, in order to adapt the low output voltages of PV modules to a dc bus voltage, while dealing with the appropriate impedance matching. In this paper, cascaded step-up converters for residential applications are used to step up the PV panel voltage to the dc bus voltage of a dc-NG. This dc-NG is based on conventional control architecture for residential applications. The used controller is based on the voltage and current control using Pulse Width Modulation (PWM) controller. The dc distribution bus is supplied by PV panels, ac utility and a storage battery. The storage battery is connected to the main dc bus through a dc-dc bidirectional converter (BDC). Numerical simulations of a case study corroborate the theoretical predictions of the paper.

At present, estimating surface solar radiation by exploiting satellite data is a very promising method. Indeed, satellite observations provide an alternative means to derive solar radiation due to their spatially continuous observations for large areas. In the present work, we propose a method to estimate solar radiation at earth’s ground using Landsat 8 OLI/TIRS data. This method will eventually allow us to create a space maps of the solar radiation distribution received on ground. The chosen study area is Oran $(35^{circ}42$`23``N, $0^{circ}34$`43``W) in Algeria.

Results obtained from alkanes, alkanols and ethers show that the new fitted PCSAFT parameters are much better comparing with those exist in the literature. Moreover, for alkanes, the percent AAD values of liquid density and vapor pressure are under 2.2%, for alkanols, the AAD is 1.95% for liquid composition and 0.07% for vapor composition, then for ethers, the AAD is 0.85% for liquid composition and 0.19% for vapor composition.
