Title: Research on MPPT of photovoltaic power generation system
Abstract: As to the problem of tracking slow and easy vibration in photovoltaic power generation system,an improved incremental conductance algorithm was proposed.The algorithm acquired the output current and voltage of PV at first,and then filtered and tracked the maximum power point.If the deviation between outputting power and the nominal maximum power point was larger,the algorithm used constant step size increment,and could rapidly reach the maximum power point;if the deviation between the outputting power and the nominal maximum power point was smaller,the algorithm used dichotomy and variable step size increment.The algorithm was achieved in TMS320F28335 DSP platform,and succeeded application in MPPT system.The experimental results prove that this tracking system can rapidly track maximum power point,and can reduce power lose.
