The proposed paper is mainly focused on achieving stable operation of microgrid having reconfigurable architecture leading to huge variation in network parameters. The variation in network parameters may not be easily handled by conventional droop controllers, which are mainly designed while assuming fixed network configuration. However, these assumptions become invalid for a microgrid having small mesh network with reconfigurable structure. Therefore, it is most important for a microgrid to remain stable not only during various changes in droop characteristics but also during dynamic topological changes. The $L_1$ controllers are well known for their robustness under wide parametric variations. Therefore, a novel $L_{1}$ adaptive controller has been designed to achieve enhanced stability of microgrid under the varying network configuration and variable droop controller characteristics. The proposed method is simulated in MATLAB/ Simulink and verified on field programmable gate array (FPGA)-based real world hardware platform.

${}_1$ 带小网状网络的交流微电网自适应下垂控制

所提出的论文主要侧重于实现具有可重构架构的微电网的稳定运行,从而导致网络参数的巨大变化。网络参数的变化可能不容易被传统的下垂控制器处理,这些控制器主要是在假设固定网络配置时设计的。然而,对于具有可重构结构的小网状网络的微电网,这些假设变得无效。因此,对于微电网来说,最重要的是不仅在下垂特性的各种变化期间而且在动态拓扑变化期间保持稳定。这$L_1$控制器以其在广泛参数变化下的鲁棒性而闻名。因此,一部小说 $L_{1}$自适应控制器旨在提高微电网在变化的网络配置和可变下垂控制器特性下的稳定性。所提出的方法在 MATLAB/Simulink 中进行了仿真,并在基于现场可编程门阵列 (FPGA) 的现实世界硬件平台上进行了验证。
