Smart grid is now making a significant impact on energy management. In fact, adding smart meters to the power grid allow a better system monitoring and control. In addition, it has also allowed a variety of data to be captured. Handling consumers needs is beneficial for a wise energy production and consumption. However, a challenging task in energy management concerns estimating the future energy demand of consumers, especially when consumers change their behavior. A key element to tackle this issue, is by analyzing smart grid data, and discovering hidden patterns and factors that can effectively be used to predict energy consumption. In this paper, we are interested in the effect of external variables on energy consumption. We first present the state of art of energy load forecasting approaches, also highlight the challenges associated with big energy data. Then we provide a comparison of machine learning approaches for energy load production in a big data context. Experimental results show the contribution of external variables on the model’s accuracy and interpretability.

This paper proposes a new approach for forecasting the coordinated Electric Vehicles (EVs) charging and discharging that minimizes the EVs charging cost, based on the day-ahead electricity price (DAEP) subject to the EVs state of charge (SOC) limits, the EVs maximum power charger, the EVs batteries full charging at the end of the charging period. Besides, the EVs initial state of charge (SOC0) has been calculated based on the EVs daily driving mileage, while Latin Hypercube Sampling (LHS) has been applied to deal with the EVs arrival, departure time and SOC0 uncertainties. The proposed optimal strategy enables EVs users to make a profit of 14.79€ while they need 2.17€ to charge their EVs in the uncoordinated scenario. Furthermore, the comparison between the real and the estimated results show that the charging cost based on the real SOC0 values is 2.88% and 27% higher than the charging cost based on the estimated SOC0 values for coordinated and uncoordinated scenarios respectively.

In this study, four donor-$pi$-acceptor dyes based on on benzocarbazole as donor have been designed by varying the bridge groups. Their optoelectronic and photovoltaic properties have been evaluated using density functional theory (DFT) and time-dependent DFT (TD-DFT) methods. Several key parameters have been investigated to reveal the influence of the modulation of the spacer group in improving light-absorbing capacities and enhancing the intramolecular charge transfer. From the results indicated that the molecule Dye-c show the best performance among the designed dyes, showing low-lying HOMO energy level (-5.29 eV), small energy gap (2.47 eV), a maximum wavelength of 446 nm. This contribution can provide an efficient guidance for the design of efficient D-$pi$-A dyes for dye-sensitized solar cells (DSSCs).

In this article, we study the participation of a DFIG-based wind turbine in frequency control in the event of a fault affecting the grid frequency. The method presented in this paper is based on the combination of primary control and the inertial response: The first controller is to produce less power than its maximum available. Therefore, we will create an active power reserve to exploit to support production in the grid frequency drop event. The second makes it possible to exploit part of the kinetic energy stored in the turbine at the start of the occurrence of the frequency fault to support the production.Therefore, this work presents the integration of these control structures as well as the study of their performance in the case of a wind turbine based on DFIG and controlled by the Backstepping technique. The results are obtained by a simulation in the MATLAB / SIMULINK environment.

In this paper, a five parameter extraction method for a single diode model of photovoltaic panels is proposed. The method is based on an iterative algorithm and able to estimate the electrical parameters from the panel’s datasheet information. Three steps are used to extract the five single diode model parameters. In the first step, we estimate analytically the ideality factor using the different information from the panel’s datasheet. In the second step, we formulate three analytical equations that permit us to find the parallel resistance, the saturation current and the photo-current as function of the series resistance and the ideality factors. The third step allows us to determine the optimal value of the series resistance using an iterative procedure that minimizes the error between the theoretical and the experimental maximum power values. The proposed method is applied to the polycrystalline silicon photovoltaic KC200GT solar module under standard test conditions (STC) and under different irradiations and temperatures. The results show a good agreement between the simulated data and the experimental measure extracted from datasheet.

This paper presents experimental and predicted results of volumetric properties for two biodiesels: Soybean Oil Biodiesel (SOB) and Waste Cooking Oil Biodiesel (WCOB) compared to the Normafluid as commercial diesel. Densities of SOB and WCOB were measured from 298.15 K to 393.15 K and from 0.1 MPa to 140 MPa, using an Anton Paar high-pressure vibrating tube densimeter (DMA HPM), whereas, the density of Normafluid was collected from literature. The density was predicted using the Tait Equation of Stat. This equation shows an efficiency of the prediction of the density of all products presented in this work with AAD=0.01% for each compound. Therefrom, thermodynamic properties as isobaric expensivity, $alpha_{p}$, and isothermal compressibility, кT, were determined over wide pressure and temperature ranges. $alpha_{p}$ and кT, have the same behavior as a function of temperature and pressure, while commercial diesel has a higher values of $alpha_{p}$ and кT than those of biodiesel at high temperature and low pressure, this information is of major importance in design engineering.
本文介绍了两种生物柴油:豆油生物柴油(SOB)和废食用油生物柴油(WCOB)的体积特性的实验和预测结果，并与normfluid作为商业柴油进行了比较。在298.15 K ~ 393.15 K和0.1 MPa ~ 140 MPa范围内，采用安东帕高压振动管密度计(DMA HPM)测量了SOB和WCOB的密度，而normfluid的密度采用文献收集。密度用Tait方程进行预测。该方程显示了本研究中所有产物密度的预测效率，每种化合物的AAD=0.01%。由此，在较宽的压力和温度范围内，确定了等压成本$alpha_{p}$和等温压缩率кT等热力学性质。$alpha_{p}$和кT作为温度和压力的函数具有相同的行为，而商品柴油在高温和低压下的$alpha_{p}$和кT值高于生物柴油，这一信息在设计工程中具有重要意义。

This paper shows an analysis between the analytical design of photovoltaic power station filter and a real case filter. Indeed, the analytical filter considered in the design phase is an LCL filter, while the real case is an LLCL filter. This difference could impact the current harmonics rejected on the grid and breaks grid codes.

Exploiting the solar energy resources of Morocco will certainly reduce its dependency on imported fossil fuels and can also lead to the reduction of the Kingdom’s energy bill. In order to study whether the implementation of a very large scale photovoltaic under Moroccan climate is technically and economically feasible, we present in this paper a techno-economic assessment of 100 MW Photovoltaic power plant for the electricity production in Oujda city (eastern Morocco), and we compare it with Dagget city (California - USA) and Almeria (Spain), where they are both countries are the pioneers of solar power-generation. Solar Advisor Model software is used to evaluate the monthly energy production, annual energy output, Capacity factor and the Levelized Cost of Energy (LCOE). The results indicate that the annual energy generation for the plant supposed installed in Oujda is 187.11 GWh, the performance ratio is 79 %, the capacity factor is 19.5 %, and finally, the LCOE is 0.06 $/kWh, which is quite interesting. These results are supposed to encourage the Moroccan government to exploit a large-scale photovoltaic for electricity production, which will lead to a sustainable development of this region of Morocco and encourage the government to start manufacturing its own PV panels to create new jobs and reduce the cost of importing panels from other countries.

Reducing carbon dioxide emissions and air pollution resulting from the extensive use of electric power generated by fossil fuel is becoming the priority of most governments. Investing in wind energy is increasing exponentially in some countries targeting an acceptable level of air pollution. Studies of the effect of lightning strokes on wind power generators and the behavior of their grounding systems are constantly growing. It is becoming a necessity to develop faster and more accurate simulation tools and to use more sophisticated models. Despite the existence of a number of analytical models for transient studies, they are limited by a quasi-static approach. The main objective of this paper is to study the theoretical aspects related to the calculation of the physical quantities of wind turbines grounding systems and to simulate their performance based on the electromagnetic model.
