2015

This paper provides a comprehensive review of the maximum power point tracking (MPPT) techniques applied to photovoltaic (PV) power system available until March, 2014. A good number of publications report on different MPPT techniques for a PV system together with implementation. But, confusion lies while selecting a MPPT as every technique has its own merits and demerits. Hence, a proper review of these techniques is essential. Since, MPPT is an essential part of a PV system, extensive research has been revealed in recent years in this field and many new techniques have been reported to the list since then. In this paper, a detailed description and then classification of the MPPT techniques have made based on features, such as number of control variables involved, types of control strategies employed, types of circuitry used suitably for PV system, transient responce and practical/ commercial applications. This paper is intended to serve as a convenient reference for future MPPT users in PV systems.

A review study of photovoltaic array maximum power tracking algorithms

There are numerous maximum power point tracking (MPPT) algorithms for improving the energy efficiency of solar photovoltaic (PV) systems. The main differences between these algorithms are digital or analog implementation, simplicity of the design, sensor requirements, convergence speed, range of effectiveness, as well as hardware costs. Therefore, choosing the right algorithm is very important to the users, because it affects the electrical efficiency of PV system and reduces the costs by decreasing the number of solar panels needed to get the desired power. This paper provides the comparison of 62 different techniques used in tracking the maximum power based on literature survey. This paper is intended to be a reference for PV systems users.

Maximum Power Point Tracking of PV Arrays using Different Techniques

The increasing demand for electricity and depleting fossil fuels made the solar Photovoltaic (PV) systems to be a better alternative for the future power requirements. The fact that the output of the PV system is dependent upon the solar irradiance and temperature demands a means to maximize the output of the PV system by continuously tracking the maximum power point(MPP) under changing atmospheric conditions. This paper presents the design and implementation of various techniques like perturb and observe (P&O) method, incremental conductance method, constant current method and constant voltage method. The performance of the techniques have been analyzed through simulation

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.

A Comparative Study on Maximum Power Point Tracking Techniques for Photovoltaic Power Systems

This paper provides a comprehensive review of the maximum power point tracking (MPPT) techniques applied to photovoltaic (PV) power system available until January, 2012. A good number of publications report on different MPPT techniques for a PV system together with implementation. But, confusion lies while selecting a MPPT as every technique has its own merits and demerits. Hence, a proper review of these techniques is essential. Unfortunately, very few attempts have been made in this regard, excepting two latest reviews on MPPT [Salas et al., 2006], [Esram and Chapman, 2007]. Since, MPPT is an essential part of a PV system, extensive research has been revealed in recent years in this field and many new techniques have been reported to the list since then. In this paper, a detailed description and then classification of the MPPT techniques have made based on features, such as number of control variables involved, types of control strategies employed, types of circuitry used suitably for PV system and practical/ commercial applications. This paper is intended to serve as a convenient reference for future MPPT users in PV systems. Index Terms-Maximum power point tracking (MPPT) techniques, photovoltaic (PV) array.

Design and Comprehensive Analysis of Maximum Power Point Tracking Techniques in Photovoltaic Systems

Advanced Technologies for Solar Photovoltaics Energy Systems, 2021

In this chapter the performance of various maximum power point tracking techniques for Photovoltaic (PV) systems has been presented, under uniform and non-uniform irradiance conditions. Under uniform irradiance conditions, the powervoltage curve of PV systems is nonlinear and contains one peak point whose location appertains to the irradiation and surface temperature of the PV system. Partial shading on PV modules reduces the generated power than the maximum power generated from each module separately. The traditional techniques of tracking the maximum power point are designed to track the global peak but they always failed to capture the exact point. In this chapter, different techniques of maximum power point tracking have been introduced, analyzed, and simulated. MATLAB, SIMULINK, and PSIM software have been utilized to simulate the PV systems under various shading conditions. Furthermore, the response of the different techniques of maximum power point trackers has been evaluated...

Simulation and Analysis of Maximum-Power-Point-Tracker for Photovoltaic Arrays

2013

This paper presents an efficient way to search for the photovoltaic array's (PA's) maximum power point (MPP). The incremental conductance is used as the basis for the search process. The algorithm consists of two stages. First, it tries to reach the nearby MPP determined by the operating voltage based on the empirical formula. A modified incremental conductance algorithm is then utilized to reach the real MPP. Finally, a digitized high-performance solar photovoltaic power conversion system is developed and verified. The design method based on the adaptive MPPT algorithm is proposed to generate the optimal power output. A DSP-based control system for synchronization of plural AC power sources has also been implemented.
