Abstract
The power quality of PV generation is greatly affected by the maximum power point tracking (MPPT) algorithm. Researching an improvement measure of MPPT algorithm, is an effective way to reduce the power quality problems caused by the PV generation system and improve the micro grid power quality. The drawbacks of a commonly used variable step perturbation algorithm and its effects on the power quality of micro-grid are analyzed. According with the drawbacks, an improved variable step perturbation algorithm is proposed combining with the mathematical model of PV cells. And the simulation analysis show that through improving the MPPT algorithm can effectively improve the power quality of micro-grid which contains PV generation system.
