Abstract:
 For the wide range of input and high utilization requirements of photovoltaic power generation system,the research achieved maximum energy capture througha variable step iteration golden section control. A dynamic simulation model was established based onengineering software,the results of which shows the feasibility of the system meanwhile stability of the algorithm. Energy conversion hardware cir-cuit with floating-point digital signal processor TMS320F28035 was designed,as well theimplementation in software based on golden section control. The experimental results verify the effectiveness of the algo-rithm. The system converged at new maximum power point in 30ms after the condition changed,which showed a fast convergence time. The high efficiency system has astrong robustness. The implementation of the algorithm can provide a reference for engineering practice and application of photovoltaic power gener-ation system.
