摘要: Abstract The maximum power point (MPP) may be not tracked successfully because of the constraint conditions among some circuit parameters. To solve this problem, in paper, tracking (MPPT) photovoltaic (PV) system with inverter are found by analyzing its integrated mathematical model. Based on them, a variable-weather-parameter (VWP) MPPT control strategy is proposed. By use it, complex for combination DC/DC converter and can avoided, which ensures lower hardware cost, shorter design period better performance. Finally, simulation experiments show that proposed accurate reasonable regardless varying irradiance, temperature or load, verify feasible available to track MPP successfully, illustrate there performance than conventional perturb observe (P&O) method fuzzy method.
