“…The IPSM algorithm application to MPPT worked correctly under adverse circumstances, to be specific, the irradiance changes. Authors in [37] simulate a PV array in which the algorithm applied to the MPPT for partial shading condition was a PSM, its fastest response time was 24 ms, in contrast with the 4 ms time response of the simulation test performed in this paper, as seen in Figure 11. Having a similar PV panels connection previously proposed by the authors, this result led to an improvement in the time response by 96%, however, for the same hardware in the loop test, the response to find the MPP was 3 s. The differences between the simulated and emulated results are due to the different data transmissions speed of the devices.…”

This article presents a method for the Maximum Power Point Tracking (MPPT) of a Photovoltaic (PV) panels array with partial shading, applying an Improved Pattern Search Method (IPSM). The method is simulated in PSIM @ and then implemented in hardware in the loop system, emulating the PV array on an industrial computer (Speedgoat) that allows real-time emulations and the IPSM is applied in an Arduino DUE. The experiments were carried out with TP245S-20/WD, KYOCERA KC200GT, YINGLY SOLAR JS65, and MSX60 photovoltaic panels. The results are the proper MPPT with changes in partial shading over time, inducing the increase and decrease of the maximum power point. The results obtained are the search for the global maximum power point in a matrix of panels in which, due to partial shading, it might have several local maximum power points, and thanks to the IPSM algorithm, it always manages to find the global maximum power point. Finally, the results are compared with other methods where it was found that IPSM had faster answers.

“…The limitations are oscillation around the MPP in steady state condition and tracking deviation from the maximum operating point under fast changing environment condition. The accurate perturbation value is important to provide good performance in both steady state and dynamic response [2], [14], [21], [22], [24], [25].…”

Improving power efficiency for a Photovoltaic (PV) system becomes important issue for researchers. To achieve maximum power extraction from PV panels, different kinds of Maximum Power Point Tracking (MPPT) methods have been investigating in the literature. In all techniques, direct and indirect mode approaches can be implemented. Based on the physical application of the PV system under different condition, the efficiency and convergence speed become important. In this paper, a grid connected simple single stage PV system by using different MPPT methods in direct and indirect modes has been analysed to find out the best mode and technique for a specific PV system application. Three of the most preferred MPPT algorithms: the perturb & observe (P&O), incremental conductance (Inc. Cond.) and fuzzy logic control (FLC) have been performed in MATLAB Simulink and compared their performance in direct and indirect modes in terms of convergence speed and tracking accuracy by the proposed single stage PV system. The results show that direct mode MPPTs have better tracking accuracy but less convergence speed than indirect MPPTs. Therefore, indirect mode MPPTs present better performance for the rapid atmospheric changing applications. Additionally, FLC based MPPT exhibits almost best tracking performance for direct and indirect modes.

“…It has a current source with a diode in parallel, making it a non-linear current source, which directly converts the solar irradiation into electricity by diffusing the motion of electron and holes within the PV cell. As it is a non-linear current source, it is essential to form the PV source to always operate on its MPPT so that maximum power can be attained [24]. Figure 1 illustrates the I-V curve characteristics at 25 • C. As irradiance decrease from 1000 W/m 2 to 100 W/m 2 , the I PV also decrease accordingly.…”

The penetration of renewable energy sources into the conventional power systems are evolving day by day. Therefore, in this paper, a photovoltaic (PV) connected thermal system is discussed and analyzed by keeping PV to operate at maximum power point (MPP). The main problem in the interconnection of these systems is load frequency fluctuations due to different load changing conditions. The model predictive controller (MPC) has the ability to predict the target value at real-time with fast convergence. Therefore, MPC is proposed to negate this problem by giving minimum oscillation. The comparison analysis is carried out with other conventional controllers, including genetic algorithm-based PI, firefly algorithm-based PI and PI controller. Simulation results clearly exhibit the outclass performance of MPC over all other controllers.
