摘要

本文提出了一种针对部分被遮光罩覆盖的光伏阵列的新型功率补偿系统。该控制策略采用双电层电容器(EDLC)作为储能器件，在主系统和控制系统的系统配置上都优于使用电池或DC-DC变换器。此外，EDLC的能量流可以通过仅检测EDLC端子电压的继电器来简单地控制。通过仿真分析验证了该系统的控制特性。并通过实验室样机系统的实验结果验证了系统的可行性。

A power compensation strategy based on electric double layer capacitors for a partially shaded PV array

This paper presents a novel power compensation system for a photovoltaic (PV) array that is partially covered by a shade. The control strategy adopts electric double layer capacitors (EDLC) as a energy storage device, which brings advantages into the system configuration of both main and control system over using a battery or DC-DC converters. In addition, the energy flow of the EDLC can be simply controlled by a relay with only detecting the terminal voltage of the EDLC. The control characteristics of the proposed system are examined by simulation analyses. And, the system feasibility is demonstrated and verified from experimental results of the laboratory prototype system.
