The control and operation of electronic systems
relies and depends on the availability of  the  power supply.
Rechargeable batteries have been more pervasively used as
the energy storage and power source for various electrical and electronic systems and devices, such as communication
systems, electronic devices, renewable power systems, electric vehicles, etc. However, the rechargeable batteries are
subjected to the availability of the external power source when it is drained out. Because of the concern of battery life,
environmental pollution and a possible energy crisis, the
renewable solar energy has received an increasing attention
in recent years. A fuzzy logic control based grid tied
uninterruptible power supply integrating renewable solar
energy can be used for electrical and electronic systems to
produce power generation. This paper presents the design and implementation of fuzzy logic control based grid tied
uninterruptible power supply integrating the renewable  solar power energy system. The uninterruptible power supply (UPS) system is characterized by the rechargeable battery that is connected  with  the Photovoltaic Panel through the DC/DC converter,  the  utility AC through the AC/DC  converter  and the load is connected through the DC/AC converter. The whole operation is controlled by the fuzzy logic algorithm. A complete hardware prototype system model of the fuzzy logic control based  on the  grid tied uninterruptible power supply integrating with the  renewable solar energy is designed and implemented. The operation and effectiveness of the proposed system is  then  demonstrated by  the  actual and  real-time implementation of  the  fuzzy logic control grid tied operation 
uninterruptible power supply integrating renewable  solar
energy connected to the rechargeable battery bank and a PIC
microcontroller platform for fuzzy logic control and operation.

One of major problems related with PV-applications
is common mode currents. The issue can be solved in two
ways: galvanic decoupling of AC-grid and chopping the
common mode currents by additional actively controlled
circuitry. Flyback converter is good solution for MPPT
tracking for PV-modules up to 100-150 W with galvanic
decoupling. The problem of designing of this type of converter
is that most of design guides and literature is dedicated to
consumer electronics applications. MPPT converter design
have different starting points of calculations. The paper
contains the suggested approaches to the calculations, design
recommendations, considering the specific nature of PVsources
and NOCT model of PV-module.
The approach calculations, design guidelines, recommendations
and simulation of power electronics part of MPPT
converter and experimental results with implemented circuit
are presented and discussed. In order to increase the efficiency
during tests the circuit was upgraded with active clamp. After
the tests active clamp was upgraded to the forward active
clamp topology. The efficiencies and key waveforms of voltages
are compared and analyzed.

—This paper proposes an accurate detection scheme that effectively differentiates the partial shading from the uniform change of irradiance. By doing so, it avoids the unnecessary global peak search which results in a drop of the maximum power point tracker (MPPT) efficiency. The detection is achieved by calculating the irradiance at two designated points on the I-V curve namely, i.e. the short circuit (Isc) and MPP (Impp) currents. Since the mismatch of irradiance at these two points differs greatly for the partial shading and uniform irradiance change, the occurrence of the former is easily discriminated. To prove its effectiveness, the scheme is integrated into perturb and observe (P&O) and particle swarm optimization MPPT algorithms using a buck-boost converter. Its performance under several partial shading and dynamic shading condition is simulated using Matlab/Simulink and validated using the dSpace DS1104 platform. It only requires 3 samples to determine if partial shading occurs; without the scheme, an unnecessary scans of the entire P-V curve is initiated. Consequently, MPPT transient efficiency is increased by 30-35%. In addition to this, the calculated irradiance is utilized to update the open circuit voltage of the array, thus eliminates the use of temperature and irradiance sensors.

The purpose of this work is to design and to discuss various strategies to optimize the production of a wind energy conversion chain based on the doubly fed induction generator (DFIG), by capturing the maximum power at the wind turbine, using maximum power point tracking (MPPT) and pitch control. The proposed controls allow the generator to monitor the optimal operating points of the turbines regardless of wind speed variations, system parameters disturbance, and parameters variation. Simulation of WECS based on a 1.5 MW wound rotor induction generator under MATLAB/SIMULINK is carried out using the PI controller (PIC), RST controller and fuzzy logic controller (FLC). Analysis and comparisons are made for different operating scenarios: Reference tracking, robustness under variable wind speed conditions and parameters variation. The application of FLC provides a very interesting outcome for the robustness and the dynamic challenges.

The simulation results prove that the novel MPPT tactic has a high convergence speed to locate the MPP, especially at fast solar irradiation and load variation with zero oscillation under steady-state operation, which takes less than 9.6 milliseconds (ms) under the MATLAB/Simulink software and 0.24 microseconds (μs) under Proteus environment. That means it is about six times faster than P&O and five times faster than INC MPPT methods, and its tracking efficiency is between 99.40% and 99.86%. Furthermore, the novel MPPT tactic shows the best tracking accuracy and better ability to mitigate power losses under overall simulation scenarios compared with other traditional MPPT methods.

The target of this paper is the enhancing the PV system performance by improving the PV and DC-DC boost converter output power. On the PV side, a new proposed MPPT technique in [1] is used to track the available maximum power (MPP). On the other hand, on the boost converter side, high ripples minimizing are obtained in the output power, current, and voltage. Next, three test simulations under stable and variable solar irradiation are carried out to examine and evaluate the tracking effectiveness of the proposed MPPT technique compared with the celebrated Increment of Conductance (INC) MPPT method. The simulation results prove the best performance and the good ripples minimizing in the input and output side of the boost converter using the proposed MPPT tactic, where the ripple amplitude can be reduced six times compared to the INC MPPT method. In addition, the proposed MPPT tactic presents a better efficiency in both static and dynamic conditions with an average value attending 99.86% and 99.6%, respectively, compared to the INC MPPT method which presents an average efficiency of 94.23% and 95.28% in static and dynamic conditions respectively. In this work, the MATLAB/Simulink tool was used in the simulation implementation.

An improved MPPT tactic is proposed in this paper for temperature variation in photovoltaic panel sourced boost converter. In this article the improved algorithm has easily added to a novel MPPT tactic proposed in [1]and it can significantly improve the tracking accuracy, without increasing the implementation complexity of the PV systems. The improved technique has been simulated in Matlab/Simulink environment. In addition, the proposed algorithm yielded consistently more favorable results than did the MPPT algorithm in [1].

Enhancing PV system performance and efficiency requires improving the extraction of the maximum available power from the PV generator and reducing the output losses from the used DC-DC converter. A new proposed MPPT technique in the second cited reference is used to track the available maximum power (MPP) from the PV generator. On the other hand, the interleaved boost converter is used to minimizing the output current, voltage, and power ripples. Two simulation scenarios are provided to examine and evaluate the tracking effectiveness of the proposed MPPT technique using the interleaved boost converter. The first one is carried out under sudden variation of solar irradiation however the second is made under slow variation of solar irradiation. The simulation results demonstrate the good performance of the proposed approach combining the new proposed MPPT algorithm with the interleaved boost converter compared to the conventional boost converter. The simulation implementation is carried out using the MATLAB/Simulink software tool.

This paper presents an intelligent control technique for the Maximum Power Point Tracking (MPPT) of a photovoltaic (PV) system using adaptive neuro-fuzzy inference system (ANFIS) under variable solar irradiation conditions. The MXS 60 PV Module specifications is considered for the analysis and models of solar PV module and a DC/DC Boost converter are developed in MATLA/SIMULINK environment. Initially, an MPPT controller is designed using Perturb and Observe (P&O) method. However, this conventional method cannot track rapid changes in the solar irradiation effectively. Hence, an intelligent controller is designed using ANFIS which draws much energy and fast response under continuously changing operating conditions. The PV module with proposed MPPT controller is analyzed in stand-alone mode.  The major disadvantage with PV system is its uncertain and intermittent power output which depends on weather conditions. PV module alone cannot supply reliable power to the isolated load effectively. To overcome this, PV module can be connected to the grid. It serves two purposes; in case of deficit solar irradiation, power can be taken from the grid and when there is surplus irradiation, power can be fed to the grid.  In order to predict the power supplied to the load and grid under different operating conditions sensitivity analysis has been carried out for the PV system with designed MPPT controller is simulated using HOMER Pro Software.

Modern scientific advances have enabled remarkable efficacy for photovoltaic systems with regard to the exploitation of solar energy, boosting them into having a rapidly growing position among the systems developed for the production of renewable energy. However, in many cases the design, analysis, and control of photovoltaic systems are tasks which are quite complex and thus difficult to be carried out. In order to cope with this kind of problems, appropriate software tools have been developed either as standalone products or parts of general purpose software platforms used to model and simulate the generation, transmission, and distribution of solar energy. The utilization of this kind of software tools may be extremely helpful to the successful performance evaluation of energy systems with maximum accuracy and minimum cost in time and effort. The work presented in this paper aims on a first level at the performance analysis of various configurations of photovoltaic systems throug...

This paper develops and discusses an improved MPPT approach for temperature variation with fast-tracking speed and reduced steady-state oscillation. This MPPT approach can be added to numerous existing MPPT algorithms in order to enhance their tracking accuracy and response time and to reduce the power loss. The improved MPPT method is fast and accurate to follow the maximum power point under critical temperature conditions without increasing the implementation complexity. The simulation results under different scenarios of temperature and insolation were presented to validate the advantages of the proposed method in terms of tracking efficiency and reduction of power loss at dynamic and steady-state conditions. The simulation results obtained when the proposed MPPT technique was added to different MPPT techniques, namely, perturb and observe (P&O), incremental conductance (INC), and modified MPP-Locus method, show significant enhancements of the MPP tracking performances, where the average efficiency of the conventional P&O, INC, and modified MPP-Locus MPPT methods under all scenarios is presented, respectively, as 98.85%, 98.80%, and 98.81%, whereas the average efficiency of the improved P&O, INC, and modified MPP-Locus MPPT methods is 99.18%, 99.06%, and 99.12%, respectively. Furthermore, the convergence time enhancement of the improved approaches over the conventional P&O, INC, and modified MPP-Locus methods is 2.06, 5.25, and 2.57 milliseconds, respectively; besides, the steady-state power oscillations of the conventional P&O, INC, and modified MPP-Locus MPPT methods are 2, 1, and 0.6 watts, but it is neglected in the case of using the improved approaches. In this study, the MATLAB/Simulink software package was selected for the implementation of the whole PV system.

The photovoltaic energy is one of the renewable energies that has attracted the attention of researchers in the recent decades. The photovoltaic generators exhibit nonlinear I-V and P-V characteristics. The maximum power produced varies with solar insolation and temperature. It requires maximum power point tracking (MPPT) control techniques to extract the maximum available power from PV arrays. Due to partial shading condition, the characteristics of a PV system considerably change and often exhibit several local maxima with one global maxima. Conventional Maximum Power Point Tracking techniques can easily be trapped at local maxima under partial shading. This significantly reduced the energy yield of the PV systems. In this paper, various MPPT algorithms for uniform insolation and partial shading conditions are reviewed with their merits and demerits. Also, some new algorithms are proposed which are shown to be more efficient than the existing ones.
