Photovoltaic panel configuration parameter setting method

How to reconfiguration a PV module?

The proposed reconfiguration process is obtained by inserting switch matrix between the PV modules, the required number of switches is 2 × M × N single-pole m-throws. The proposed configuration can be controlled to enhance the current and voltage capabilities of the PV modules.

What is PV reconfiguration?

The reconfiguration of PV systems consists of modifying the electrical connections between the panels to increase the power production of a PV array operating under mismatched conditions. In the literature, the reconfiguration applications use different hardware structures, where the most common architectures are SP and TCT.

What are the performance parameters of PV array configurations?

The FF and efficiency of all configurations are nearly 73.99% and 14.1541% respectively. For all the configurations, the mismatch loss is almost zero and the voltages and currents generated at GPPs are almost same. TABLE 1. Variation in performance parameters of PV array configurations b. Under corner shading pattern c. Under center shading pattern

Why is a reconfiguration process important in photovoltaic system?

A reconfiguration process is an important task in photovoltaic system which aims to choose the best configuration for maximizing output power. In this paper, some of the most developed PV reconfiguration strategies for different PV array topologies presented in the literature have been discussed.

How a PV module is connected?

A connection of the number of PV cells in series can obtain the PV module and the connection of number of PV modules in series or in parallel to get required load voltage and currents referred to as PV array which is shown in Figure 1B. The relation between the PV module's output current and voltage is specified by Equation (2).

Which PV array configuration is better under different PSCs?

The authors in Reference 15 investigated the performance of series (S), Series-Parallel (SP), Bridge-Link (BL), and Honey-Comb (HC) PV array configurations under various PSCs by considering 5 × 5 PV array and they concluded that in most of the cases the performance of HC configuration is superior.
