| 摘 要： | 光照变化条件下基于改进的扰动观察法是一种最大功率点跟踪（MPPT）优化算法，可分离来自光照变化的影响，追踪扰动，并根据光照变化，用这些信息来优化追踪。当光照快速变化时，这种策略可以更迅速、更好地追踪，而且在稳态条件下使得在最大功率点处振荡更小。仿真结果显示，该方法在光照变化环境下可以快速、准确地追踪到最大功率点。

| Abstract: | Under the conditions of irradiation change, an improved method of perturb and observe （P＆O） is a kind of optimized algorithm of maximum power point tracking （MPPT）, which can separate the effects of the irradiation change to track perturbation and uses this information to optimize the tracking according to the irradiation change. When the irradiance is changing fast, this strategy can track faster and better, and in the steady-state conditions it leads to lower oscillations around the maximum power point. The simulation results show that the improved method provides a quick and accurate tracking even in the conditions of irradiation change. |
