摘要
为实现光伏发电系统的快速功率响应,研究了一种新型的双PI闭环控制策略.通过在传统PI控制基础上增加前置反馈和后置反馈机制,显著提高了系统的动态响应速度和稳态控制精度.仿真结果表明,新型双PI闭环控制策略在电压波动和负载变化情况下,能够更快速地调节系统输入和输出,确保更高的功率响应速度和电压、电流的稳定性.
Abstract
This paper investigates a novel dual-PI closed-loop control strategy to achieve rapid power response in photovol-taic(PV)systems.By adding pre-feedback and post-feedback mechanisms to the traditional PI control,the dynamic re-sponse speed and steady-state control accuracy of the system are significantly improved.Simulation results show that the new dual-PI loop control strategy can quickly adjust system inputs and outputs under voltage fluctuations and load chan-ges,ensuring higher power response speed and stability of voltage and current.
