A sociocultural study on solar photovoltaic energy system in India: Stratification and policy implication

Cleaner production is a simple defensive mechanism to protect the environment from pollution and depletion of resources. It is also envisioned to minimise the waste and capitalise on natural resources with effective utilization. Solar energy is a natural resource which can be converted into electricity using photovoltaic (PV) system. This article sheds insights on the implementation of solar PV system with interdisciplinary views and analyse motives and barriers for PV adoption by different citizen groups in India. A survey was conducted to understand the people's perception on solar PV energy system and to determine the level of acceptability among the citizens. The survey information was synthesised and consolidated from various perspectives and the result consigns the research findings into technical, human and socio-economic components. The findings were synthesised through cross-cultural, comparative and mixed-method research outcomes by means of Structural Equation Modelling (SEM), Dendrogram diagram and biplot interpretation. Statistical tools such as ‘IBM-SPSS Amos’ and ‘R’ language programming were also used to interpret the results. This article concludes by specifying the barriers that limit the retrofitting interventions, suggests possible measures and policies to overcome such barriers and promote solar energy in India.

Hardware Implementation of Solar Photovoltaic System based Half Bridge Series Parallel Resonant Converter for Battery Charger

The long established battery chargers are having many drawbacks such as prominent ripple charging current, less efficiency and bulky in size. To overcome these drawbacks of conventional battery charger, several charging circuits have been proposed and inevitability force to design a high-performance battery charger with small in size and improved efficiency. In this paper solar photovoltaic system based half-bridge series–parallel resonant converter (HBSPRC) charger is proposed for battery interface. The converter is designed to abolish low and high-frequency ripple currents and thus take full advantage of the life of secondary battery circuit. This is achieved by designing converter switches turn on at zero current and zero voltage with switching frequency greater than that of resonance frequency which leads to freewheeling diodes need not have very fast reverse-recovery characteristics. The performance of the power converters depends upon the control method adopted; in this work fuzzy logic controller is used for controlling the output voltage of HBSPRC. The fuzzy control scheme for the HBSPR converter has been designed and validated in hardware implementation of HBSPRC switching technique. From the results, it is found that the proposed battery charging system which reduces the switching loss and voltage stress across the power switches which increases the efficiency of the converter.

Real‐time implementation of SPV system with DSTATCOM capabilities in three‐phase four‐wire distribution system

This study deals with a real-time implementation of solar photovoltaic (SPV) grid integrated system possessing distributed static compensator (DSTATCOM) capabilities with three-phase four-wire voltage source converter (VSC) topology using least mean eighth control algorithm. The proposed system has an SPV array, a VSC, three single-phase non-linear loads connected to the grid and a ripple filter. The SPV and VSC together behave as a DSTATCOM and additionally supplies SPV power to the grid. The DSTATCOM reduces the total harmonic distortion of the grid currents, maintains the voltage of point of common coupling and improves the power factor. The maximum extraction of incident solar power on SPV array is achieved through an incremental conductance maximum power point tracking technique. The behaviour of the system is studied by developing a prototype with an SPV array simulator.
