摘要： The photovoltaic system is able to provide a maximum power to the load to a point of particular operation which is usually called as the maximum point of power (MPP); thus, it is important to use a maximum power point trackers (MPPT) to achieve the photovoltaic maximum power nevertheless the unsteady environmental conditions. The (P&O) algorithm has used to be a classical solution for the purpose of tracking the maximum power, however, there are several drawbacks in this technique such as it causes an oscillation nearby the maximum power point. To overcome the existing problems in the classical method a lot of researches have been done. This article provides an intelligent method to improve and optimize the performance of the maximum power point tracker associated with the PV array with the help of fuzzy logic technology, as well as compare its behavior by report has other techniques (P&O) used in the photovoltaic systems controls. The simulation results are developed under MATLAB/Simulink software. An extensive simulation have been done and compared with the traditional (P&O) technique under various climatic conditions to provide the effectiveness of the proposed controller.

摘要： In this work, we use the Backstepping controller with integral option to track the maximum power point of a photovoltaic (PV) system. The controller is applied in three cases of the solar panel. In the first case the PV without resistances: series and shunt resistances, while in the second case the PV with series and shunt resistances, the third case consist of PV with constant series resistance, and therefore, shunt resistance values are changed up to plus 50%, without forgetting the variation of the weather conditions solar irradiation and temperature, to check whether the controller is rigor and robust enough. The system under study contains PV associated to a load via DC/DC Boost converter, and we have a Backstepping control design integrated the integral option added to ameliorate the strong control performance of nonlinear controller. The Backstepping strategy for getting the optimal power point and system stability is used Lyapunov’s analysis. The system and the control method is analyzed with a simulation model that was based Simulink/Matlab.

摘要： Maximum power point tracking (MPPT) is an algorithm to extract maximum available power from a solar photovoltaic system associated with DC-DC power converters. Conventional MPPT methods like Perturb and Observe (P&O) algorithm and Incremental Conductance algorithm are inefficient, as they cannot differentiate between local and global MPP. In addition, they oscillate on reaching MPP due to their fixed step size. Advanced methods using Artificial Neural Networks and Artificial Intelligence based methods were proposed to overcome these problems. These advanced methods have high tracking efficiency and they are fast. Particle Swarm Optimization algorithm based MPPT method a simple and basic method of Artificial Intelligence based MPPT methods. This paper presents a brief review of advanced artificial intelligence based MPPT methods alongside the generic SPV model utilized for simulation.

摘要： The robust ensemble Kalman filter (EnKF) based control is proposed for multifunctional three phase grid-connected solar energy conversion system with distribution static compensator (DSTATCOM) abilities. The robust EnKF based control facilitates the various functionalities of power quality (PQ) enhancement of the distribution grid such as grid currents balancing, harmonics current mitigation and unity power factor. The improved real coded genetic algorithm (RCGA) based metaheuristic approach is used to tune the proportional integral (PI) controller of the DC link voltage. Simulation results comparative dynamic performance, which demonstrates that the robust EnKF exhibits superior response as compared to state of the art techniques. The relative computational complexity of the proposed robust EnKF algorithm is analyzed with conventional stochastic filters such as Kalman filter (KF) and extended Kalman filter (EKF). To substantiate the proposed control, a prototype is realised in the laboratory and test results demonstrate satisfactory response of the grid-connected system subjected to various dynamic scenarios such as load currents imbalancing, harmonics compensation, imbalanced grid voltages, under voltage and over voltage. The response of grid currents are achieved within the IEEE-519, 1564 and 1159 standards.

[IEEE 2018 International Seminar on Application for Technology of Information and Communication (iSemantic) - Semarang, Indonesia (2018.9.21-2018.9.22)] 2018 International Seminar on Application for Technology of Information and Communication - Comparison of First Order Differential Algorithm, Perturb and Observe (P&O) and Newton Raphson Methods for PV Application in DC Microgrid Isolated System
摘要： The necessary for energy always increases every year, so it is necessary energy alternative to overcome the phenomenon. From some alternative energy that is currently widely developed is solar energy. Unfortunately the use of solar energy with the help of solar panels produces power that varies according to the irradiation received and the temperature on the solar panel. Irradiation is the emission of energy coming from the sun. This parameter causes the output power characteristic curve to be non-linear. And the power generated by PV has not reached the maximum power point. To overcome this problem requires an arrangement to find the maximum power point and make it stable at that point. Therefore, this paper proposes "Comparison of First Order Differential Algorithms, Perturb and Observe(P&O) and Newton Raphson Methods for PV Application in DC Microgrid Isolated System" so that the maximum power point can be achieved quickly and accurately. In this paper we tried to compare 3 methods of First-order Differential, P & O (Perturb and Observe) and Newton Raphson by using ZETA Converter as its object in switching settings. By using the simulation can be obtained the results of tracking speed and maximum power level. The results of the simulation show that error power the First-order Differential is 4%, P & O is 0.26389% and Newton Raphson is 0.45178%. It is evident that Raphson's newton algorithm is superior to speed and accuracy.

摘要： This paper proposes a new global MPPT method for PV array under non-uniform insolation. The proposed method first tracks the knee point using I-V characteristic which is near to the local peak of the P-V curve. Then it compares the measured power at various knee points to find the region containing global peak. Finally, it uses P&O to find the exact global peak. Thus the proposed method avoids the use of P&O to track every local peak. The performance of the proposed algorithm is further verified in MATLAB/Simulink. The results show that the proposed method is able to track global peak of PV array during Partially Shaded Conditions.
