Energy efficiency Optimization Strategy for the Coordinated Operation of Photovoltaic Power Generation and LED Lighting
WU Meng
Abstract：To address the energy efficiency losses caused by multi-stage"DC-AC-DC"conversion in traditional photovoltaic(PV)power generation and LED lighting systems,this paper proposes an energy efficiency optimization strategy for coordinated operation based on DC characteristics.Firstly,a PV-LED DC microgrid architecture is constructed to analyze the energy-saving potential of reducing conversion stages.Secondly,a direct drive strategy based on source-load impedance matching and a source-load linkage control mechanism based on DC Bus Signaling(DBS)are proposed to achieve millisecond-level power balance and flexible consumption under PV fluctuations.Finally,a hierarchical control architecture incorporating intelligent sensing and edge computing,along with a cross-domain interface standardization scheme,is designed.The results indicate that this strategy effectively eliminates redundant AC/DC conversion links,resolves the spatiotemporal mismatch between source and load,and significantly enhances the overall energy utilization rate and operational stability of the system.
