摘要

本文提出了一种用于直流微电网能量管理的五电平双向飞电容DC-DC变换器拓扑结构。与传统的双电平DC-DC转换器不同,在这种拓扑结构中存在多个飞行电容器,可以在提高效率的情况下具有更高的电压增益转换比。五个电压电平的存在使变换器的优势在于降低了功率开关上的电压应力,并在其输入端采用了小尺寸的电感滤波器。此外,具有双向潮流的能力使转换器能够有效地将储能设备(如电池)集成到高压直流微电网中。利用所建立的数学模型,提出了一种有限控制集模型预测控制(FCS-MPC)算法,以实现双向潮流和三飞电容电压平衡的多目标。此外,考虑了由光伏系统、负载和电池组成的直流微电网,以评估所设计的FCS-MPC算法在不同负载和光伏功率注入下的有效性。

Operation and Control of Five-level Bi-directional Flying Capacitor DC-DC converter in DC microgrid
This paper presents a five-level bi-directional flying capacitor DC-DC converter topology for energy management application in a DC microgrid. Unlike traditional two-level DC-DC converter, the presence of multiple flying capacitors in this topology brings the possibility of having a higher voltage-gain conversion ratio at enhanced efficiency. The existence of five voltage levels give the converter an advantage of having reduced voltage stress on its power switches and a low-sized inductor filter at its input. Additionally, the capability of having bi-directional power flow enables the converter to integrate energy storage devices such as the battery to a high voltage DC microgrid effectively. A finite control set - model predictive control (FCS-MPC) algorithm is formulated using the developed mathematical model in order to yield the multi-objective of bi-directional power flow and three flying capacitor voltage balancing. Furthermore, a DC microgrid comprising photo-voltaic (PV) system, load, and battery are considered to assess the effectiveness of the designed FCS-MPC algorithm under varying load and PV power injections.
