“…Also the output power of PV cell is dependent on irradiance and ambient temperature, which are dynamic variables throughout the day timings. In order to extract maximum power from the PV panel, MPPT techniques are applied [12][13][14]. Block diagram of a typical PV system in terms of components is shown in Fig.…”

The trend and need of shifting towards renewable energy sources for electricity generation, has attracted researchers towards photovoltaic (PV) systems for last few decades. Since PV generator has nonlinear behavior, and its output power is a function of solar irradiance and ambient temperature, therefore need of developing maximum power point tracking (MPPT) techniques remains the interest. Among various MPPT techniques, Perturb & Observe (P&O) and Incremental-Conductance (IC) are dominant. This paper describes these two algorithms and compares them in terms of their computational complexity and oscillations near maximum power point (MPP) using MATLAB ® & Simulink ® . Also testing conditions are based on the real environmental data collected at NED University, Karachi.

“…Electrical energy from photovoltaic is currently regarded as the prerequisite sustainable resource for both stand-alone as well as grid connected applications, since it is abundant and clean, offers zero input fuel cost, and is distributed throughout the earth [1]. In practical cases, photovoltaic modules operate over a highly intermittent nature of temperature and irradiance but the electrical parameters provided in the datasheet are only for the standard test conditions (STC).…”

“…As the PV systems are generally integrated with specific control algorithms in order to extract the maximum possible power, it is highly imperative that the MPP is achieved effectively and thus it is needed to design a model from which the MPPT algorithm can be realized in an effective way. Some MPPT techniques have been proposed in [1,3,4,10]. However, for simplicity, this paper adopts the Perturb and Observe (P&O) method for MPPT.…”

This paper proposes a simple, accurate, and easy to model approach for the simulation of photovoltaic (PV) array and also provides a comparative analysis of the same with two other widely used models. It is highly imperative that the maximum power point (MPP) is achieved effectively and thus a simple and robust mathematical model is necessary that poses less mathematical complexity as well as low data storage requirement, in which the maximum power point tracking (MPPT) algorithm can be realized in an effective way. Further, the resemblance of the P-V and I-V curves as obtained on the basis of experimental data should also be taken into account for theoretical validation. In addition, the study incorporates the root mean square deviation (RMSD) from the experimental data, the fill factor (FF), the efficiency of the model, and the time required for simulation. Two models have been used to investigate the I-V and P-V characteristics. Perturb and Observe method has been adopted for MPPT. The MPP tracking is realized using field programmable gate array (FPGA) to prove the effectiveness of the proposed approach. All the systems are modeled and simulated in MATLAB/Simulink environment.

“…Consldenng these issues, it is very important to operate a PV array at a point where maximum power could be obtain � d. Maximum Power Point Trackers (MPPT) are used for thIS purpose. A variety of MPPT techniques have been reported in literature [1,3]. These methods vary in their accuracy, cost of implementation, types of sensors required, ability to operate properly in shading conditions, and complexity of circuit etc.…”

The Power vs. Voltage (P-V) characteristic of a photovoltaic (PV) array is characterized by the presence of multiple maxima under partial shading conditions. Out of these only one is the global maximum. Conventional Maximum Power Point Tracking (MPPT) techniques may fail to track the global maximum which results inconsiderable power loss. Therefore, special MPPT techniques are adopted for MPP tracking of PV arrays under partial shading conditions. This paper propose � a technique which tracks the MPP of the array under partial shading conditions. In the proposed technique the PV array is disconnected from the load for negligibly short period of time and is connected to an external capacitor. During the charging time of the capacitor, the proposed circuit tracks the global MPP. This circuit is easy to implement and shortens the time duration needed for scanning the P-V curve of the array.
