基于功率增量变化百分比的变步长功率追踪方法研究

Variable Step Size Power Tracing Method Based on Percentage of Power Increment Variation

针对传统太阳能发电功率追踪中存在的精度低或不稳定等问题,提出一种以功率增量变化百分比为控制因素的变步长功率追踪方法。仿真结果表明,文中提出的方法不仅具有较好的稳定性,也能避免振荡问题。

To solve the problems of low precision or instability in traditional solar power generation power tracking,a variable step size power tracking method based on the percentage change of power increment is proposed.Simulation results showed that the proposed method not only had good stability,but also can avoid oscillation.
