Comparative Study of Different Configuration Techniques to Address the Outcome of Partial Shading Conditions on Solar Photovoltaic System

Abstract

As per energy and power productivity of a solar photovoltaic (SPV) system is evaluated, Partial Shading Conditions (PSC) play a significant role. Under PSC, the panels of a SPV modules receive various levels of solar irradiance, as a result power generation of a SPV system diminishes, and these losses in SPV panels may be decrease by changing the configuration of the panels in array/module. The panels may be configure in many different configuration such as Series(S), Parallel (P), Series Parallel (SP), Total Cross Tied (TCT), Bridge Linked (BL), and Honeycomb (HC) to improve the output energy and power efficiency. This work is aimed to present all the configuration that already been presented in literature and result of PSC on SPV systems are referenced and analyzed. There are four configuration 4×4 array of solar photovoltaic panels to be discussed in this paper. Four configuration are Series parallel (SP), total cross tied (TCT), bridge linked (BL), and honey comb (HC). Four simulated models were performed to decide to effect of shadow with 10 shading patterns. The simulated results shows as a power against voltage (PV) curves of 4×4 array of SPV under PSC for above mentioned configuration. The PV curve of the proposed configuration is enhanced the power efficiency and the minute and exact finding of global maximum peak is simpler. The test of the simulated modules and its theoretical results ensure the effective implementation of this techniques in hardware setup also. It is confront that this work will be a reference of useful and important information for researchers in Solar panel area. The work presented in this papers envisages to be a source.

Reconfiguration and Analysis of PV Array based on Particle Swarm Optimization of Solar Plant

“…It has an advantage over other linking methods as in this method, the losses are reduced to a minimum, and it gives the best result under different shading patterns [10], [11]. The performance analysis of TCT is tested on different shading patterns, and results are verified after simulations [13]. Dominance square-based array reconfiguration scheme is evaluated [12] for power loss reduction in solar PV systems.…”

Recent developments of polymer-based encapsulants and backsheets for stable and high-performance silicon photovoltaic modules: materials nanoarchitectonics and mechanisms

“…In the past, researchers improved PV cell efficiencies with the help of different materials, introduced new designs (e.g., bifacial PV modules), and changed the module conguration. [21][22][23][24] The currently emerging bifacial PV modules are also capable of using light that is re-ected from the ground (Fig. 1b), while conventional PV modules only use sunlight that hits the top of the PV module.…”

Robust reconfiguration strategies for maximum output power from large-scale photovoltaic arrays under partial shading conditions

“…Series (S) and parallel (P) interconnections are the basic configurations that are used to provide the required power output [23]. Other existing configurations include SP (Series-Parallel), BL (Bridge-Linked), TCT (Total-Cross-Tied), and HC (Honeycomb) which are modified versions of basic configurations [24]. In the SP configuration, the SPV panels are connected in series and then in parallel to achieve the required output power.…”
