摘要

本文采用人工神经网络技术对太阳能光伏板电源的最大功率点进行跟踪。在光伏(PV)面板和单相电压源逆变器(VSI)的直流链路之间接口有升压变换器。同步参考帧(SRF)-锁相环(PLL)用于同步VSI与电网电源。VSI控制保持恒定的直流母线电压。为了保证系统整体性能稳定和可控性,提出了一种基于人工神经网络的LCL滤波器双级1相VSI的TMPP算法。带谐波补偿器(HC)的比例谐振控制器控制VSI电流。在实际动态情况下观察了所提出的系统行为,结果令人满意。

Artificial Neural Network Based Double Stage Grid Connected Solar Photovoltaic Supply System
In this paper, an artificial neural network technique (ANN) is used for tracking of maximum power point (TMPP) of a solar photovoltaic panel based power supply (SPPBPS). A boost converter is interfaced between the photovoltaic (PV) panel and DC link of single-phase voltage source inverter (VSI). A synchronous reference Frame (SRF)-Phase-locked loop (PLL) is used to synchronize the VSI with the grid supply. The VSI control maintains constant DC bus voltage. An ANN based TMPP is proposed for double stage 1-phase VSI with LCL filter to ensure stable overall system performance, and controllability. A proportional resonant controller with harmonic compensator (HC) controls VSI current. The proposed system behavior is observed under real dynamic situations and found satisfactory.
