Using the model of the solar cell for determining the maximum power point of photovoltaic systems

2007

This paper proposes a technique for accelerating the convergence to the maximum power point of photovoltaic (PV) systems based on the model obtained from manufacturer's generator data. The influence of the temperature over the PV array performance is considered, and no measurement of solar radiation is required. No knowledge of the load model and no expensive sensor circuitry are necessary. The tracking speed is much faster than non model-based techniques at the expenses of an increase in the computational complexity. Simulation and experimental results are presented and demonstrate the feasibility of the proposed solution.

Investigate the maximum power point of photovoltaic system at different environmental conditions

International Journal of Electrical and Computer Engineering (IJECE), 2023

The main objective of this work is to implement a circuit-based simulation model of a photovoltaic (PV) cell in order to investigate the electrical behavior of the practical cell with respect to some changes in weather parameters. The simulation model consists of three subsystems: photovoltaic cells, DC/DC converter and MPPT controller based logic fuzzy control. The maximum power control function is achieved with the appropriate power control of the power inverter. Fuzzy logic controller has been used to perform MPPT functions to get maximum power from the PV panel. The proposed circuit was implemented in MATLAB/Simulink. The obtained results show that the output sequence is non-linear and almost constant current to the open circuit voltage and the power has maximum motion to voltage for certain environmental conditions.

Review of the modern techniques of Maximum Power Point Tracking for the solar photovoltaic systems

The energy generation of a solar photovoltaic (SPV) system is directly dependent on solar radiation intensity and its availability. The energy generation from the PV module is also affected due to climatic parameters such as ambient temperature, humidity, rainfall, wind and dust. To extract the maximum power from PV array Maximum Power Point Tracking (MPPT) technique is applied. At varying operating conditions, MPPT algorithms automatically detect the maximum power and supply to the load. In the present paper ten different MPPT techniques have been identified and analyzed. These different techniques have been well developed in the papers individually. In the present study a comprehensive review of popular MPPT techniques is presented.

Ecofriendly green power technology i.e. Solar Photovoltaic based electricity generation is the rapid developing and a promising source of energy for today's and future world. This has been catalyzed due to the increment of global warming and the depletion of fossil fuel. In this paper, an extensive literature review is conducted for the evaluation of the maximum power point tracking techniques to get the maximal energy extracted from the Photovoltaic panel considering the effects of electrical and environmental parameters.

A study on Maximum Power Point Tracking techniques for Photovoltaic systems

There is an increase in global energy demand day by day. The best source of energy that can be chosen is renewable energy. Solar energy is available in abundance. Hence to meet the growing demand, solar energy is converted to electrical energy by using Photovoltaic (PV) systems. The PV systems have non-linear characteristics. Their energy conversion efficiency is very low. Hence Maximum Power Point Tracking (MPPT) is used to increase the efficiency of the system. It is used to ensure that maximum available energy is extracted under varying environmental conditions such as solar irradiation, temperature, load, etc. This further ensures that the available generating systems are used efficiently given the high cost of PV systems. Various algorithms have been implemented to design an MPPT based PV system. This paper gives a comparative study of the available algorithms to implement MPPT. The implementation of MPPT techniques began in 1970’s. These techniques differ in efficiency, complexity, cost, power generated and so on. Before choosing an appropriate technique to design a PV system, it is necessary to study the characteristics of the available methods. This is important as the effective utilization of the available PV infrastructure is required. This paper presents the study of the available techniques on the basis of their characteristics. Major and common techniques namely, Perturb and Observe, Incremental Conductance, Fractional Open Circuit Voltage, Fractional Short Circuit Current and Particle Swarm Optimization have been studied. MATLAB simulations have also been presented. A concluding report has been presented to find out the most optimized technique.
