Building a photovoltaic system is the process of designing, selecting and calculating the ratings of the equipment’s employed in the system. This process depends on a variety of factors such as geographical location, solar irradiation, and load re quirements. this paper presents a practical way to calculate the elements and components of the Stand-Alone PV energy system, And procedure an economic analysis for the system, will allow GUI designed by MATLAB knowledge of these components depending on the efficiency of the Inverter, power solar panels and capacity of batteries in local market, taking into account the climatic factors and hours of solar radiation in the system installation area, as well as the cost of the system and the payback time.
This paper deals with the analysis and study of performance of solar panels, so we choose working on the solar panel (module) MSX-50, in addition to improve his power by tracking the maximum power point, this is done by using boost (step up) choppe r to obtain the largest possible capacity of solar panel. We will determine a mathematical model equivalent to the real solar panel (not ideal) through studying photovoltaic cells, where we will use the iterative method in addition to the Newton-Raphson algorithm in order to determine the value serial resistance of module Rs parallel resistance of module Rp. As has been the implementation of perturbation and observation p&o algorithm in addition studying and designing the circuit of step up (boost) chopper, and selection the components (coil L, capacitor C), based on both the operation frequency f, ripple factor of output voltage and output current . Based on the our study, we have performed a modeling process of the solar module MSX-50 using MATLAB/SIMULINK program, where we designed a graphical user interface GUI to display the module characteristics and calculate resistance Rp and Rs, in addition to build an algorithm p&o and design circuit of boost (step up) chopper. The proposed model has been applied to the ohmic load according to the principle of the maximum power point tracking MPPT, and discuss the results of two cases wich are the following the solar module is connected directly to load, connected through chopper driven by p&o algorithm.
With the increase in reliance on solar energy to produce electricity, so many maximum power point tracking techniques for photovoltaic panels were developed to maximize the produced energy and a lot of these are well established in the literature. These techniques vary in many aspects such as: simplicity, convergence speed, digital or analogical implementation, required sensors, cost, range of effectiveness, as well as in other aspects. This paper presents a comparative study of ten widely-adopted mppt algorithms; their performance is evaluated from energy point of view using the simulation tool (Matlab), considering different solar irradiance variations. Also, an economic evaluation has been made to make a comparison according to performance and cost, to determine the optimal choice.
Since the invention of Fuzzy logic and fuzzy control, the latter has been growing in spread and importance in many applications and devices in many life aspects. This maybe due to the easy use of a fuzzy control system, and for being far of math co mplications. Even if the plant model is unknown, a self-organizing fuzzy controller (SOFC) can improve the response of an already exist linear control table, or even can build a control table from scratch, by assessing current performance of the controller and adjusting the control table accordingly. This paper provides a simple article that shows how to design and use a self organizing fuzzy controller, through a simulation example using MATLAB & Simulink in which a variable torque loaded DC motor speed regulation is done. The simulation showed the ability of the controller to provide a good response and decrease speed error by a notable amount at load torque changing times. This paper can be used as textbook material for students or researchers interested in the field of adaptive control, especially self-organizing fuzzy control.
This research deals with improving the efficiency of solar photovoltaic (PV) power systems using a Maximum Power Point Tracker controller (MPPT controller), based in his work on the Maximum Power Point Tracking techniques via the direct control met hod. Which used to control the duty cycle of DC-DC Voltage Converter, to achieve the photovoltaic system works at a Maximum Power Point under different atmospheric changes of the solar insolation and ambient temperature. In this context, our work is focused on the simulation of the components of the power generating system, such as the photovoltaic system, DC-DC Boost Converter and a MPPT controller in Matlab/Simulink environment. The simulating of the MPPT controller was based on several algorithms such as: Constant Voltage algorithm, Perturb and Observe algorithm and Incremental Conductance algorithm by using Embedded MATLAB function. The simulation results showed the effectiveness of the MPPT controller to increase the photovoltaic system power compared with non-use of a MPPT controller. The results also showed the best performance of MPPT controller based on Perturb and Observe and Incremental Conductance algorithm, compared with constant voltage algorithm in tracking the Maximum Power Point under atmospheric changes.
