Design and Implementation of a Novel High-performance Stand-alone Photovoltaic LED Lighting System

Abstract

This paper presents a novel high-performance standalone photovoltaic (PV) lighting system which can provide functional illumination based on high power White LEDs. An improved incremental conductance Maximum Power Point Tracking (MPPT) method is proposed in PV system to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A novel strategy to charge the battery is designed from the analyses and comparison results. In order to provide a steady-state operating environment for high power White LEDs, a specially designed LED drive module is implemented. Further more, a self-adapting dimming control is designed to maintain a stable indoor illuminance. Experimental results show the performance of the proposed photovoltaic lighting system.

Analysis and implementation of soft‐switched bidirectional buck‐boost DC‐DC converter for solar PV‐fed LED street lighting systems

“…The load on the grid can be reduced by using renewable energy resources. Several architectures of an SPV-fed LED street lighting systems (SLS) [3][4][5][6][7] are reported in the literature. It offers more advantages like high luminous efficacy, long life, better color rendering properties, and fast response.…”

“…The power consumption can be reduced by using energy-efficient light-emitting diode (LED) lighting systems. Flyback and Cuk converters, 3 buck converter, and active clamp forward converter, 4 two similar sepic converters, 5 integrated sepic-forward converter, 6 and integrated buck-boost and boost circuits 7 are some of the reported topologies for battery charging/discharging applications. 2 In order to reduce energy consumption, an energy-efficient lighting system like the SPV-fed LED-street lighting applications are gaining wide importance.…”

A High-Performance Stand-Alone Solar PV Power System for LED Lighting

“…In PV lighting system, choosing the electronic components is very important for cost reduction, reliability, and efficiency [2,7]. PV panel and high power white LED array are the most expensive components of the overall system, so the microcontroller board should make full use of them.…”

“…LED lighting system supplied by batteries is one of most popular solutions to home, public lighting, vehicle, and signalizing lighting system [5][6][7][8][9][10][11][12].…”

“…The parameter is inverse proportional to the current absorbed from the PV panel to get fast convergence to the MPP tracker. It is expected that this algorithm shows some inherent oscillation around the MPP [7].…”
