Bifurcation and Chaos in Converter Interfaces in Solar PV Systems-A Review

Abstract

The paper attempts to present a detailed study of the nonlinear phenomena that includes bifurcations, sub-harmonics and chaos in an effort to arrive at the appropriate choice of converter interface suitable for specific PV systems and evolve criterions for their design and control. The resurgence of switching dc-dc converters as power processing units in renewable energy applications appear to open up new perceptions for harnessing energy efficiency. The focus orients to review the modelling techniques used for nonlinear analysis in the different operating modes of the converter and identify the gap in the related domain with special relevance to the converter interfaces in solar PV systems. The exercise incites to explain the forms of bifurcations, the routes to chaos and the associated control techniques for arbitrating its significance in this perspective. The benefits of analysis of nonlinear phenomena in regulatory applications claim a new space in energy processing applications and forge to explore their role as maximum power point (MPP) trackers. The emphasis endeavours to enhance the scope of use of solar energy and offer a fresh dimension to support the clean energy act and perpetuate the desire to enliven a greener world.

The Impact of Urbanization and Industrialization on Energy Security: A Case Study of China

“…Zeng et al [67] constructed energy security indicators using multicriteria decision-making techniques based on the priorities stipulated in EU energy policy, and described the energy security trends of Baltic countries from the economic, energy supply chain, and environmental dimensions. (4) Expected welfare loss evaluation method: Yergins [68], Bohi and Toman [41], Winzer [61], Nikolaidis and Poullikkas [69], and Subashini and Ramaswamy [70] pointed out multiple layers of changing risk sources and influences of energy security which were manifested by significant differences during distinct periods and in different countries. These influences can be discussed under the uniform standards through expected welfare loss, thus enabling an overall evaluation on energy security.…”

A Unique Bifurcation Structure in One-Dimensional Model of Current-Controlled Step-Up DC–DC Converter with Photovoltaic Module

“…Studies of power conversion circuits using PV module include maximum power point tracking control [12][13][14]. On the other hand, the bifurcation phenomenon is also being energetically analyzed [15,16]. The occurrence of bifurcation phenomenon in power conversion circuits increases current and voltage ripples [17].…”
