Journal ArticleDOI

Performance assessment of free standing and building integrated grid connected photovoltaic system for southern part of India

TL;DR: This study will assist architects and wider community to design buildings roofs with GPV system which are more aesthetic and account for noise protection and thermal insulation in the region of equatorial climate zones.
Journal ArticleDOI

Analysis of Fractional Order Sliding Mode Control in a D-STATCOM Integrated Power Distribution System

TL;DR: In this article, a fractional-order sliding mode control (FOSMC) was proposed for a D-STATCOM to compensate the low power distribution system by injecting/absorbing a specific extent of the reactive power under disturbances.
Journal ArticleDOI

An Original Hybrid Multilevel DC-AC Converter Using Single-Double Source Unit for Medium Voltage Applications: Hardware Implementation and Investigation

TL;DR: In this article, an original hybrid multilevel DC-AC converter configurations are proposed by using single-double source unit for medium voltage applications by derived by hybridization of single and double source units with polarity changer and cascaded with full-bridge converter.
Journal ArticleDOI

Experimental Investigations Conducted for the Characteristic Study of OM29 Phase Change Material and Its Incorporation in Photovoltaic Panel

TL;DR: In this paper, a heat transfer network was developed to minimize the experimental difficulties and represent the working model as an electrical resistance circuit, where liquid phase change material (PCM) is filled directly on the back surface of the PV module to overcome the conduction barrier and PCM attains the thermal energy directly from the PV modules.
Journal ArticleDOI

Infrared Thermography Based Defects Testing of Solar Photovoltaic Panel with Fuzzy Rule‐Based Evaluation

TL;DR: The new Thermal Pixel Counting algorithm to detect the above faults based on three thermal profile index values is proposed and results have been provided to validate the proposed method.
