Abstract: Based on the optimized global maximum power point tracking algorithm,this paper uses voltage loop and current loop frequency division control to efficiently and accurately track the global maximum power point under moving shadow occlusion.Through designing multi-mode energy supply ways with photovoltaic and power battery and matching efficient electricity power management systems,the efficient and coordinated energy operation from the working mode to energy management is achieved to provide off-grid extended range power for the bus.
Key words: bus photovoltaic technology; global maximum power point tracking; efficient power management
