“…However, with the proposed approach, we overcome drawbacks due to large gains in the circuits when the gradient of the PV generator characteristics has a very large absolute value. We remark that the integrator input v is proportional to the gradient in MPPT circuits based on ESC [7], and proportional to the gradient divided by the Hessian in MPPT circuits based on NL-ESC [10].…”

“…For such a purpose, many authors have proposed different MPPT methods [1][2][3][4][5][6][7][8][9][10][11][12][13]. These methods have deserved attention not only from the power electronics field but also from the automatic control domain.…”

“…Such techniques appeared during the 1950s [12,13] and most of them use the block schema that is shown in Figure 1. Several authors have described MPPT circuits based on ESC for photovoltaic application [3][4][5][6][7]. MPPT schemas have also been applied to other power generation applications [8,9].…”

“…Thus, it can be extended to ESC methods reported in [5,7,11,13]. It should be noted that it can not be used in other ESC methods that do not use external dithering signals and can be categorized as self-oscillating ESC methods.…”

Abstract:The paper adapts the Newton-like Extremum-Seeking Control technique to extract the maximum power from photovoltaic panels. This technique uses the gradient and Hessian of the panel characteristic in order to approximate the operating point to its optimum. The paper describes in detail the gradient and Hessian estimations carried out by means of sinusoidal dithering signals. Furthermore, we compare the proposed technique with the common Extremum Seeking Control that only uses the gradient. The comparison is done by means of PSIM simulations and it shows the different transient behaviors and the faster response of the Newton-like Extremum-Seeking Control solution.

“…Based on ESC method, the other technique proposed is the sinusoidal ESC (SESC) (Leyva et al 2012). With a small modification in gradient detector, it is also called as scalar gradient based ESC (SGESC) (Ghaffari et al 2015) and this technique has been implemented.…”

Photovoltaic (PV) system is one of the reliable alternative sources of energy and its contribution in energy sector is growing rapidly. The performance of PV system depends upon the solar insolation, which will be varying throughout the day, season and year. The biggest challenge is to obtain the maximum power from PV array at varying insolation levels. The maximum power point tracking (MPPT) controller, in association with tracking algorithm will act as a principal element in driving the PV system at maximum power point (MPP). In this paper, the simulation model has been developed and the results were compared for perturb and observe, incremental conductance, extremum seeking control and fuzzy logic controller based MPPT algorithms at different irradiation levels on a 10 KW PV array. The results obtained were analysed in terms of convergence rate and their efficiency to track the MPP.Article History: Received 3rd Oct 2016; Received in revised form 6th January 2017; Accepted 10th February 2017; Available onlineHow to Cite This Article: Naick, B.
