This paper establishes a distributed cooperative control framework for multiple dc-ESs in a dc microgrid and presents the small-signal stability analysis of the system. The primary level implements a droop control to coordinate the operations of multiple dc-ESs. The secondary control is based on a consensus algorithm to regulate the dc-bus voltage reference, incorporating the state-of-charge (SOC) balance among dc-ESs. With the design, the cooperative control can achieve average dc-bus voltage consensus and maintain SOC balance among different dc-ESs using only neighbor-to-neighbor information. Furthermore, a small-signal model of a four dc-ESs system with the primary and secondary controllers is developed. The eigenvalue analysis is presented to show the effect of the communication weight on system stability. (2018-09-05, PDF, 1852KB, 下载20次)

为了提高微电网在故障条件下的稳定性,本文提出了一种超导磁储能(SMES)、有源超导故障限流器(SFCL)和分布式发电单元通过无线网络通信的协调控制。这种协调控制可以在严重或永久性故障的情况下顺利地将微电网与主电网分开,并且如果故障是次要的或临时的,则有助于微电网实现故障穿越(FRT)操作。详细介绍了建模、控制策略和网络体系结构。此外,在Matlab中实现了包括SMES、SFCL和光伏发电单元的10 kV级微电网的仿真分析。在协调控制的性能评估中,不仅考虑了严重故障和小故障,而且考虑了不同的通信延迟。结果证实了所提出的协调控制的有效性。
To enhance the stability of a micro-grid under fault conditions, this paper proposes the coordination control of a superconducting magnetic energy storage (SMES), an active superconducting fault current limiter (SFCL), and distributed generation units via wireless network communications. This coordination control can smoothly separate the micro-grid from the main network in case of severe or permanent faults, and assist the micro-grid to achieve the fault ride-through (FRT) operation if the fault is minor or temporary. Details on the modeling, control strategy, and network architecture are presented. Moreover, the simulation analysis of a 10 kV class micro-grid including the SMES, SFCL, and photovoltaic generation units is implemented in MATLAB. Concerning the performance evaluation of the coordination control, not only severe and minor faults, but also different communication delays are taken into account. The results confirm the effectiveness of the proposed coordination control. (2018-06-21, PDF, 633KB, 下载19次)
