“…The choice of the search step-size algorithm influences the oscillation around the MPP and the algorithm convergence time towards that point. For this, we find some MPPT algorithms use a variable size to make an adequate combination between precision and speed [22], [23]. One of these algorithms is that given in [23] when the fixed step size is replaced by a variable step size equal to 0,01 multiplied by the power difference.…”

To exploit the maximum power generated by the photovoltaic (PV) panel, it is necessary to use the maximum power point tracking (MPPT) controller. The main concern of MPPT algorithms is how to reach the maximum power point (MPP) quickly with less oscillation. To achieve this objective, this paper studies and compares the performance of different MPPT algorithms with a new proposed criterion of variable step size in terms of convergence speed towards the MPP and reduced oscillations around it. The proposed method utilizes a simple way to build multi-operating zones. In each field, the step size depends on the closeness to the MPP. The simulation results are obtained under Proteus and Arduino software; we use physical security information management (PSIM) software for the modeling of the PV panel and MATLAB software to display the comparative results between the different algorithms.

This paper covers a new topology, a synchronous wind turbine generator, and a solar photovoltaic generator. The Permanent Magnet Synchronous Generator is linked to the grid by back-to-back voltage source converters (BtB VSC), consisting of a two-stage rectifier and a five-stage Neutral Point Clamped inverter, operated by the Space Vector Pulse Width Modulation technique. A solar photovoltaic system has a direct interface with the capacitor of the DC link of the BtB VSCs, with no additional DC/DC conversion stage, while the efficiency of the system is maximized. This work features a Perturb and Observe algorithm Maximum Power Point Tracking for to extract the optimum power from both wind turbine and solar PV generator. The application of Space Vector Pulse Width Modulation control scheme is used for harmonics compensation THD. A proportional integral regulator is used to regulate the DC link voltage. A prototype is tested under various conditions, wind velocity variations as well as under several photovoltaic solar isolations. The present work has been treated using Matlab/Simulink. Simulation results proved efficiency provided by this controlling approach: reduced distortion of harmonic and increased power factor.

Abstract-Maximum power point tracking (MPPT) algorithm seek the MPP to maximize delivered the power of a photovoltaic panel. From several MPPT algorithms, the perturb and observe (P&O) algorithm is commonly used algorithm because of its easy implementation. However, it is not the most efficient algorithm due to the perturbation step is fixed. By using the high step size, the MPP tracking became fast but there would be a high steady state error and by using the low step size, there would be less steady state error but the MPP tracking became slow. Resulting in a waste of energy in steady-state conditions when the working point passes through the MPP and poorly dynamic performance indicated when the setpoint changes due to solar irradiation changes. In this paper, a modification variable step-size of the P&O algorithm has been proposed with setting the step-size automatically at each point of work. To validate the concept of modification variable step-size, simulation using PSIM has been carried out. Compared with the conventional P&O method with fixed step-size, the proposed modified P&O method can increase tracking speed and efficiency in the system.
