“…Thus, when the array is partially shaded by a shadow, seen in Figure 3(c), the shaded modules in array with TCT scheme are in the same row of its electrical arrangement while those in array with static scheme are in different rows, seen in Figures 3(a) and (b). Thus, the effect of shading is distributed over the static interconnected array thereby reducing the occurrence of shading of modules in the same row and enhancing the maximum power generated from photovoltaic array [14,15]. …”

“…It has been confirmed that P max of partially shaded photovoltaic arrays could be enhanced by optimizing the interconnections among its modules [8][9][10][11][12][13][14][15]. There are four typical interconnections, "series-parallel" (SP), "bridge-link" (BL), "totally cross tied" (TCT) and "honey comb" (HC).…”

“…Following, the static interconnection schemes are proposed, which is improved from TCT scheme and designed to show good performance through distributing shading effect over the array. Also, it is designed without switches, sensors and complicated control algorithms to make sure it is much economic than the electrically array reconfiguration scheme [14,15]. In [14,15], the illumination on every single module is assumed to be uniform.…”

“…Due to the serious partial shading influence on the power generation of PV arrays, Díaz-Dorado et al [17] utilized a metaheuristic method that is based on evolution strategies to calculate the best tilt angles of PV panels, considering the shading effect of obstacles and PV trackers. Indu Rani et al [18] enhanced power generation from PV modules under partial shading conditions using Su-Do-Ku Configuration approach. Paraskevadaki and Papathanassiou [19] optimized the output power of PV arrays considering shadow effect.…”

Optimal Tilt Angle of Photovoltaic Arrays and Economic Allocation of Energy Storage System on Large Oil Tanker Ship

This study optimizes the tilt angle of photovoltaic (PV) panels on a large oil tanker ship system and considers the impact of partial shading to improve the performance of the PV system. This work presents a novel method that considers the difference between the expected and real outputs of PV modules to optimize the size of energy storage system (ESS). The method also takes into account the cost of wasted power, the capital cost of the system, fuel cost and the CO2 emissions. Unlike on land, power generation using a PV on a ship depends on the date, latitude and longitude of the navigation. Accordingly, this work considers a route from Dalian in China to Aden in Yemen, accounting for the seasonal and geographical variations of solar irradiation. This proposed method adopts five conditions associated with the navigation route to model the total shipload. Various cases are discussed in detail to demonstrate the effectiveness of the proposed algorithm.

Summary This article intends to present a compendious review to extract maximum power in solar photovoltaic (PV) systems under varying environmental conditions and partial shading conditions by enumerating various circuit‐based topologies and different state‐of‐the‐art maximum power point techniques (MPPT). Partial shading reduces the overall efficiency of the PV system; therefore techniques that are dealing with partial shading play an important part in the power conditioning unit of all PV system connected to the stand‐alone mode or grid mode. Various circuit‐based topologies and various algorithms have been broadly discussed till date. As every algorithm is associated with its own merits and demerit, hence an extensive literature survey is required while planning for PV generating station under normal and partial shading condition. In this article, a comprehensive review of shading mitigation using different topologies has been done. The article on shading mitigation is broadly divided into two major groups. The first group includes all major circuit‐based topologies and the second group includes MPPT based techniques, which has been further classified into modified conventional techniques, soft computing techniques, and hybrid techniques. This comprehensive review presents an assessment of all techniques according to parameters like converter used, tracking speed, complexity, efficiency, number of sensors under partial shading condition would certainly provide a single platform to carry forward their research in solar PV application.
