In this article, the meta-heuristic algorithm PSO with PI fuzzy logic controller is proposed to develop a new control strategy of bidirectional converter (CSBC), in order to improve the stability and increase the efficiency of energy flow exchange in grid-connected photovoltaic generator (PVG) Battery hybrid system. The proposed command aims to satisfy the DC Motor load demand, manages the power flows from different parts, injects surplus energy into the grid as and when need, ensure charge-discharge battery operation even under the fluctuating condition of power generation, and stabilize the DC bus voltage. This new control has been placed in the network topology, which consists of a PVG Photovoltaic Generator, grid-connected DC/AC converter, storage battery and DC motor load. A bidirectional buck-boost converter is used for optimum exploit of power from PVG along with battery charging/discharging control, and for feeding DC motor load. The effectiveness of the proposed control scheme is demonstrated by using MATLAB / Simulink program. The results obtained, show that the proposed control provided the system with the stability of Vdc voltage, and contributed to improving the speed produced by the DC motor load. The results have been compared with the conventional control.

In this paper, a steady-state output power oscillation problem is overcome using the indirect control mode based-Perturb and Observe (P&O) implementation algorithm. This can be ensured through controlling the duty cycle input of the DC-DC boost converter using the proposed Linear Quadratic Regulator (LQR) controller. Their parameters are optimized using the Grasshopper Optimization Algorithm (GOA) where a good tracking behavior of a desired Maximum Power Point (MPP) can be guaranteed for various sudden changes in weather conditions such as absolute temperature and solar irradiance. The desired performances and robustness of the closed-loop system can be achieved by the two following stages. In the first stage, the standard P&O algorithm based-direct control mode generates a reference current perturbation using both existing electrical power and measured PV current. Accordingly, a current error perturbation is provided through the discrepancy between reference and measured currents. In the second stage, the previous current error provided in the inner control-loop is mitigated as much as possible using the stabilized LQR controller. The current control-loop problem is addressed with a detailed analysis technique of averaging and linearization, in which the linearization of actual PV-boost converter system around the desired MPP allows determining the corresponding linear plant-model. This leads to well optimize the LQR controller parameters. The performance and robustness provided by the P&O algorithm based-indirect duty cycle control are shown for sudden changes in solar irradiance and absolute temperature as well as in a wide variation of the resistive load.
本文采用基于扰动与观测(P&O)的间接控制实现算法克服了稳态输出功率振荡问题。这可以通过使用所提出的线性二次调节器(LQR)控制器控制DC-DC升压转换器的占空比输入来确保。它们的参数使用蚱蜢优化算法(GOA)进行优化,其中可以保证对天气条件(如绝对温度和太阳辐照度)的各种突然变化进行所需的最大功率点(MPP)的良好跟踪行为。通过以下两个阶段可以达到闭环系统所期望的性能和鲁棒性。在第一阶段,基于标准P&O算法的直接控制模式使用现有功率和测量的PV电流产生参考电流扰动。因此,通过参考电流和测量电流之间的差异提供了电流误差摄动。在第二阶段,使用稳定的LQR控制器尽可能地减轻内部控制回路中先前提供的电流误差。电流控制环问题通过平均和线性化的详细分析技术来解决,其中实际PV-boost转换器系统在期望MPP周围的线性化可以确定相应的线性植物模型。这样可以很好地优化LQR控制器参数。基于P&O算法的间接占空比控制在太阳辐照度和绝对温度的突然变化以及电阻性负载的大变化情况下具有良好的性能和鲁棒性。

The value of the global solar radiation GSR reaching the earth is very important because it is an essential variable for different applications. Unfortunately, solar radiation measurements are not available, most of the time, in developing countries because of the lack of measurement means. Moreover, these measurements are difficult to obtain under complicated weather conditions. Thus, solar radiation evaluation models are used. In this study, a new semi-empirical model for the estimation and prediction of the global solar radiation of Souk Ahras area in Algeria is proposed. The model developed is based on meteorological data such as daily hourly temperatures and average relative humidity required from several stations and databases, over a period of four years. The values of the regression coefficients a, b and c calculated are 0.0142, -10.6206 and 57.8367 respectively. To set the modal valid, we have applied it to 10 Algerian cities and we calculated the H/H0 ratio for each site from our model. They have been then compared with the values from the (CDER). We can conclude that our new model gives a good estimate of the average daily global solar radiation (H) for the studied regions (error between 2.49% and 8.93%) and can also be used elsewhere in areas with the same climatic conditions.
到达地球的太阳总辐射GSR值非常重要,因为它是不同应用的基本变量。不幸的是,由于缺乏测量手段,在大多数情况下,发展中国家无法获得太阳辐射的测量。此外,在复杂的天气条件下很难获得这些测量结果。因此,使用太阳辐射评估模型。本文提出了一种新的半经验模型,用于估计和预测阿尔及利亚Souk Ahras地区的太阳总辐射。该模型是根据气象数据开发的,例如从几个气象站和数据库获取的4年期间的每日每小时温度和平均相对湿度。计算得到的回归系数a、b、c分别为0.0142、-10.6206、57.8367。为了使模型有效,我们将其应用于10个阿尔及利亚城市,并根据我们的模型计算了每个站点的H/H0比率。然后将它们与(CDER)的值进行比较。我们可以得出结论,我们的新模型给出了研究区域的平均日全球太阳辐射(H)的良好估计(误差在2.49%到8.93%之间),并且可以在具有相同气候条件的其他地区使用。

Power quality is interesting issue for power conversion PV system. Further there are challenges associated with extract of maximum power and minimize the part losses in commutation. In this paper, a three-phase five-level NPC voltage source inverter (VSI) using discontinuous pulse-width modulation (DPWM) and feeding by a PV/DC-DC boost converter based on a Takagi-Sugeno T-S fuzzy controller is presented. The photovoltaic energy system is described by nonlinear equations. A T-S fuzzy model is used to transform the nonlinear equations into a fuzzy model by modeling the irradiation, temperature and output voltage parameters. The control parameters have been computed based on Linear Matrix Inequalities tools (LMI) and the stability of the system is ensured by Lyapunov approach. In the second stage for power conversion (DC/AC), a discontinuous pulse-width modulation (DPWM) is used and approved; it offers the possibility of reducing switching losses and the THD harmonic rate. The simulation was performed in the MATLAB/Simulink software using an R-L load and the obtained results are confirmed the feasibility and reliability of the proposed method for the PV conversion system.

This paper presents a new method for modeling the steady-state behavior of the currents transmitted between the windings of a transformer subjected to an inter-turn short-circuit fault (ITSC). ITSC is one of the most frequent and most damaging faults in magnetically coupled circuits, which occur in power transformers. Coupled Electromagnetic Circuit (CEMC) Model modeling the reasoning and relationships describing the operating principle of a power transformer through the electrical and magnetic parameters defined by the self and mutual inductances that influence the voltages and currents transmitted between the transformer windings. The representation of the state variable equations of a proposed model of a three-phase multi-turn transformer in healthy mode (no fault) and in degraded mode (with inter-turn short-circuit faults of 10%, 20% and 30%) has been implemented using a program inserted in MATLAB software. The simulations illustrate the evaluation of the primary and secondary currents as well as the voltage drop across a load, and the accuracy of the state model based on the coupled circuits was validated. The results obtained can provide a basis for the design of the short circuit of the multi-turn transformer.

This paper presents a hybrid feedback linearisation-based predictive direct power control strategies of the unified power quality conditioner (UPQC) combined with a photovoltaic generator (PVG) using space vector modulation technique for power quality enhancement. The PVG-UPQC is acting as a universal conditioner for power quality enhancement and renewable energy integration simultaneously, and it mitigates harmonics in both voltage and current caused by nonlinear loads in addition to reactive power compensation. The PVG-UPQC is made up of a dc bus powered by the photovoltaic generator that connects shunt and series active power filters. The shunt filter functions as a current source and compensates for current harmonics. The series filter compensates for voltage harmonics and fluctuations such voltage sag/swell by acting as a voltage source. In order to enhance the performances of PVG-UPQC, a hybrid control method based on FL -PDPC combined with a three-level SVM controller is proposed. The aims are to deliver compensation signals faster and more accurately under a variety of load conditions, as well as eliminate voltage and current harmonics while maintaining good dynamic response. The performance of the suggested control scheme is validated by extensive simulation results obtained by Matlab/Simulink for a sensitive nonlinear load. These results are compared with those obtained with a linear PI controller proves the superiority and effectiveness of FL-PDPC controller.
针对统一电能质量调节器(UPQC)和光伏发电机组(PVG),提出了一种基于空间矢量调制技术提高电能质量的混合反馈线性化预测直接功率控制策略。PVG-UPQC作为一种通用调节器,可同时提高电能质量和可再生能源的整合,除了无功补偿外,它还可以减轻非线性负载引起的电压和电流谐波。PVG-UPQC由光伏发电机供电的直流母线组成,该母线连接并联和串联有源电源滤波器。并联滤波器作为电流源,对电流谐波进行补偿。串联滤波器通过充当电压源来补偿电压谐波和波动,如电压凹陷/膨胀。为了提高PVG-UPQC的性能,提出了一种基于FL -PDPC与三电平SVM控制器相结合的混合控制方法。其目的是在各种负载条件下更快,更准确地提供补偿信号,以及消除电压和电流谐波,同时保持良好的动态响应。通过Matlab/Simulink对敏感非线性负载的大量仿真结果验证了所提控制方案的性能。这些结果与线性PI控制器的结果进行了比较,证明了FL-PDPC控制器的优越性和有效性。

This paper presents a novel and efficient optimization approach based on the Artificial Ecosystem Optimization (AEO) algorithm to solve the problem of finding optimal location and sizing of Distributed Generation (DGs) in radial distribution systems. The objective is to satisfy a fluctuating demand in a constant and instantaneous way while respecting the requirements of power loss reduction, operating cost minimization and voltage profile improvement within the equality and inequality constraints. The robustness of the proposed technique in terms of solution quality and convergence characteristics is evaluated using the IEEE-33 bus radial distribution network test system. The simulation results are compared with those of other methods recently used in the literature for the same test system. The experimental outcomes show that the proposed AEO approach is comparatively able to achieve a higher quality solution within a timeliness of computation.
本文提出了一种基于人工生态系统优化(AEO)算法的新型高效优化方法,用于解决径向配电系统中分布式发电(dg)的最佳选址和规模问题。其目标是以恒定和瞬时的方式满足波动的需求,同时尊重在相等和不相等约束下减少功率损耗、最小化运行成本和改善电压分布的要求。利用IEEE-33总线径向配电网测试系统,对该方法在求解质量和收敛特性方面的鲁棒性进行了评价。仿真结果与文献中对同一测试系统采用的其他方法进行了比较。实验结果表明,本文提出的AEO方法能够在较短的计算时效性内获得较高质量的解。

The dielectric barrier discharge (DBD) is a more efficient medium of ozone production, which requires voltages of the order of several kV and frequencies of a few tens of kHz. The principal objective of this study is to model and optimize a cylindrical-shaped ozone generator with a surface DBD that will be used in a water treatment plant. By playing on the electrical parameters (voltage, oxygen flow) and geometric parameters (the nature and diameter of the dielectric, the length of the electrode), to achieve high ozone efficiency and minimum energy consumption. It is recommended to use cylindrical surface discharge reactors with reduced diameter and electrode length and with the smallest possible oxygen circulation interval to achieve satisfactory ozone concentrations, with reduced power consumption.
介质阻挡放电(DBD)是一种更有效的臭氧产生介质,它需要几千伏的电压和几十千赫的频率。本研究的主要目的是对将用于水处理厂的具有表面DBD的圆柱形臭氧发生器进行建模和优化。通过发挥电学参数(电压,氧流量)和几何参数(电介质的性质和直径,电极的长度),达到高臭氧效率和最低的能耗。建议使用直径和电极长度较小的圆柱形表面放电反应器,并尽可能缩短氧循环间隔,以达到令人满意的臭氧浓度,同时降低功耗。
