Conventional maximum power point tracking (MPPT) algorithms are designed under assumption that all modules are uniformly insulated and therefore can be characterized by a single maximum power point (MPP). At increasing power level PV arrays become larger in area. Moreover, to achieve a reasonable voltage level modules are connected in series, creating strings. These two factors make any array susceptible for any mismatch in their current-voltage characteristics. Under partial shading condition (PSC), when PV modules receive different insulation, multiple maxima occur in power curve of the array. This leads to a tracking error of the MPP and results in significant decrease in efficiency of the system. This paper describes Global Maximum Power Point Searching (GMPPS) methods which are designed specifically for searching global MPP (GMPP). Three hardware methods, which are based on fast sweeping of the characteristics via additional circuitry are described and compared. Three-level boost (TLB) converter is utilized as a DC-DC converter performing GMPPS. Simulation results are provided with 15 kWp PV string model.

“…Therefore, the proposed SPP-FOCV method which is improvement of the standard FOCV method, is also is not intended for implementation under partial shading conditions. A lot of special MPPT methods for partial shading conditions were developed and presented in the literature [56][57][58].…”

This paper proposes two new Maximum Power Point Tracking (MPPT) methods which improve the conventional Fractional Open Circuit Voltage (FOCV) method. The main novelty is a switched semi-pilot cell that is used for measuring the open-circuit voltage. In the first method this voltage is measured on the semi-pilot cell located at the edge of PV panel. During the measurement the semi-pilot cell is disconnected from the panel by a pair of transistors, and bypassed by a diode. In the second Semi-Pilot Panel method the open circuit voltage is measured on a pilot panel in a large PV system. The proposed methods are validated using simulations and experiments. It is shown that both methods can accurately estimate the maximum power point voltage, and hence improve the system efficiency.

“…Cloud cover, trees, buildings, and bypass diodes cause numerous power peaks on the PV string [12,14]. One of the main challenges of designing MPPT schemes is to the need to quickly detect global MPPs (GMPPs) instead of searching for other local MPPs (LMPPs) under partial shading conditions (PSCs) [15]. Numerous MPPT techniques for investigating the performance of an overall PV system will be reviewed, and their advantages and drawbacks will be identified.…”

This paper elaborates a comprehensive overview of a photovoltaic (PV) system model, and compares the attributes of various conventional and improved incremental conductance algorithms, perturbation and observation techniques, and other maximum power point tracking (MPPT) algorithms in normal and partial shading conditions. Performance evaluation techniques are discussed on the basis of the dynamic parameters of the PV system. Following a discussion of the MPPT algorithms in each category, a table is drawn to summarize their key specifications. In the performance evaluation section, the appropriate PV module technologies, atmospheric effects on PV panels, design complexity, and number of sensors and internal parameters of the PV system are outlined. In the last phase, a comparative table presents performance-evaluating parameters of MPPT design criterion. This paper is organized in such a way that future researchers and engineers can select an appropriate MPPT scheme without complication.
