摘要

本文提出了一种新的控制策略，用于降低双级单相光伏逆变器中光伏电压在两倍电网频率下的振荡。它是基于分析计算的占空比补偿，能够导致一个几乎恒定的PV电压。重点研究了基于fpga的数字实现的性能优化;实验结果验证了该方法的有效性。

FPGA-based controller for mitigation of the 100 Hz oscillation in grid connected PV systems

This paper illustrates a new control strategy for reducing the photovoltaic (PV) voltage oscillations at twice the grid frequency in double-stage single-phase PV inverters. It is based on the analytical calculation of the duty-cycle compensation which is able to lead to an almost constant PV voltage. The work is focused on the optimization of the performances of the FPGA-based digital implementation; the proposed approach is validated by means of experimental results.
