“…This is due to constraints associated to the more or less limited voltage conversion ratio of the adopted DC/DC converters, to the finite voltage and current ratings of devices used in the power stage of SCPVMs and/or due to a non optimal value of the bulk inverter voltage [2] [25] [32].…”

“…In mismatching conditions, the output voltage of the SCPVMs providing higher powers can become very large, causing dangerous, potentially destroying, switch stresses. In order to avoid that the voltage stress of devices belonging to one or more SCPVMs exceeds a given maximum value V ds max , an output voltage limitation technique needs to be adopted [2]. In the case of the buck-boost topology, in addition to output overvoltage protection circuitries, also switch current limitation techniques need to be adopted [32].…”

“…A final additional aspect to take into account is represented by the impact of system parameters on effectiveness and stability of the DMPPT technique. The approach described in [2] allows to effectively analyze modules interaction and stability of a string of SCPVMs provided that the dynamics of the MPPT block in each SCPVM is slow enough for the closed-loop DC/DC converter to reach steady-state operation after each perturbation driven by the MPPT controller. Nonlinear systems stability criteria or small-signal double control loop design techniques should be adopted in cases in which MPPT techniques involving faster dynamics or nonlinear functions are used.…”

“…To mitigate the effect of partial shading and hot spot, a new topology called "DMPPT" is proposed and studied recent years [4,5]. In this topology, a DC/DC converter performs independently MPPT for each PV panel, thus eliminates the mutual effect of different PV panels, and increases the overall output power of PV array.…”

An analog integrated maximum power point tracking (MPPT) controller which is suitable for distributed MPPT (DMPPT) topology is presented in this paper. Without large numbers of external circuit components, the DC/DC converter together with its MPPT controller can be made small enough to be integrated into the junction box, which is practical and cost effective for DMPPT topology. Besides a negative feedback loop is used in the proposed system to make the output voltage of PV panel less susceptible to fluctuations of irradiation intensity and interference of switching noise. Meanwhile, an improved P&O algorithm is adopted to achieve a fast and precise tracking especially in fast changing weather conditions. Furthermore, the tracking precision is higher than 99.5% under different external environmental conditions.

An essential objective for many photovoltaic (PV) applications is represented by the so‐called maximum power point tracking (MPPT). Under uniform irradiance and ambient temperature conditions, the power versus voltage characteristic of a PV array is characterized by the presence of a unique point, termed maximum power point (MPP), where the power provided by the array itself attains its maximum value. Any other operating point leads to the extraction of a smaller PV energy. Therefore, in order to avoid the waste of PV energy, the working of the array in its MPP is mandatory. Since the position of the MPP continuously changes in time as a function of irradiance and temperature, it is necessary to continuously track it. Such an objective can be obtained by using proper MPPT control techniques. A large number of papers have appeared in the scientific literature during the last 15 years on the issue of MPPT, and as a result it may be difficult to decide the best technique for a given application. Therefore, this survey may hopefully be beneficial to students, researchers, and practitioners in PV systems. The article overviews the representative PV MPPT algorithms, organized into four main groups. The first group contains the so‐called “hill climbing” techniques, the second group contains the “curve fitting” techniques, the third group contains the “dynamical” techniques, and the fourth group includes all the techniques that do not belong to the first three groups.
