| 摘 要： | 为在光伏并网发电系统中通过应用最大功率点跟踪(Maximum Power Point Tracking,MPPT)技术提高光伏电池的利用率,针对两级式单相光伏并网发电系统,选取基于前级变换器的MPPT控制策略.该控制策略中,前级采用改进的变步长扰动观察法实现MPPT;后级通过直流母线电压反馈构成电压电流双闭环控制,实现母线稳压.运用PSIM 9.0进行建模仿真,结果表明,该控制策略能够很好地实现MPPT和直流母线稳压,系统的动态响应速度较快,稳定性较好.

| Abstract: | To improve the utilization of photovoltaic (PV) cell by the Maximum Power Point Tracking (MPPT) technology in the PV grid connected generation system, for two stage single phase PV grid connected generation system, MPPT control strategy based on the first stage converter is adopted. In this control strategy, the improved perturbation and observation method with variable step size is used to realize MPPT in the first stage; DC bus voltage regulation is achieved through the voltage and current double closed loop control which is realized by the DC bus voltage feedback in the second stage. The model of the system is established and simulated by PSIM 9.0. The result shows that the control strategy can realize MPPT and DC bus voltage regulation well with faster dynamic response and better stability. |
