The maximum power point tracking (MPPT) is a strategy that allows imposing the PV array operation point on the maximum power point (MPP) or close to it under any environmental condition. The conventional incremental conductance (INC) algorithm is the most popular algorithm. But due to the fixed step size, its response speed is low under the rapid change of the solar irradiation level or load resistance. In this paper, a new MPPT technique is proposed to enhance the response speed. It consists of two stages: (1) the computing stage and (2) the regulating stage. The computing stage includes the coarse positioning operation and fine positioning operation. And an initial value of the duty cycle is generated in the computing stage, according to the characteristics of the DC-DC converter and the characteristics of the I‐V curve. The regulating stage regulates the duty cycle of the DC-DC converter with a small step size, which can improve the tracking efficiency. And the computing stage can enhance the response speed. A simulation comparison of the proposed MPPT technique with other techniques is carried out in MATLAB/Simulink under different scenarios. The simulation results reveal that the response of the proposed algorithm is 4.6 times faster than that of the INC under these scenarios, and the proposed algorithm has higher efficiency.

“…An alternative solution is to use the distributed approach, the classical layout of which is shown schematically in Figure 2 [32][33][34][35][36]. In this case, each PV module is equipped with a DC/DC converter that performs the MPPT function.…”

“…Moving away from these ideal assumptions toward more realistic situations, the energy performance of the distributed approach depends on the power stage efficiency and on the network topology. While the dependence of the distribute approach's efficiency on the environmental conditions and on the power stage efficiency have been discussed extensively in literature, as highlighted in [31][32][33][34][35], the same discourse cannot be extended to the role assumed by the dynamic reconfiguration of SCPVM-like tools for improving the energy performance of the distributed approach. Until now, reconfiguration techniques and distributed MPPT (DMPPT) have been considered as two alternative techniques.…”

The following two approaches can address the drawbacks associated with mismatching phenomena in photovoltaic (PV) plants: distributed maximum power point tracking (DMPPT) architecture and reconfigurable PV array architecture. Until now, these two approaches have represented alternative solutions. In this paper, for the first time, it is suggested that the two approaches can be used together. In particular, it will be shown how the joint adoption of the DMPPT and reconfiguration approaches can improve the performances of mismatched PV plants; here, performance is understood as the best compromise between the efficiency and reliability of the entire PV system. Numerical results confirm the above assumptions, providing the hints for the development of innovative reconfiguration techniques suitable for distributed applications.

“…Maximum power point tracking (MPPT) is one of the main functions carried out by power electronic interfaces that connect photovoltaic (PV) sources to loads and grid. Many MPPT techniques have been presented and discussed in the literature [1][2][3][4][5]. Among them, the perturb and observe (P&O) technique has emerged as one of the simplest, but nonetheless efficient, MPPT techniques and is widely accepted as a benchmark MPPT technique [6][7][8].…”

In this paper, a novel maximum power point tracking (MPPT) technique, which has been named T4S (a technique based on the proper setting of the sign of the slope of the photovoltaic voltage reference signal), is presented and discussed. It is specifically designed with reference to a single-stage grid-connected PV system. Its performance is numerically compared with that of the well-known and widely used perturb and observe (P&O) MPPT technique. The results of the numerical simulations confirm the validity of the proposed MPPT technique which exhibited a slightly better performance, under stationary and also time-varying irradiance conditions. In addition, the T4S technique is characterized by the following features: it does not require explicit power detection or calculation and, moreover, it allows the tracking of the maximum average power injected into the grid rather than the tracking of the maximum instantaneous power extracted by the PV source.
