Seeking the improvement of frequency and voltage regulation of distributed energy resources (DERs) in islanded microgrids, this paper presents a novel distributed control paradigm based on distribution-level phasor measurement units (D-PMUs) monitoring. First, a novel strategy denoted synchrophasor aggregation is proposed. This strategy takes advantage of the high resolution, low latency and time-stamped synchronized measurements provided by D-PMUs to obtain a local foreknowledge of DERs steady-state operating condition during the system dynamics. Based on this information, novel measurement-based control parcels are developed to provide stabilizing and corrective adjustments of generators contribution. These controllers are able to effectively improve DERs dynamic performance, i.e. damping oscillations, overshoot and frequency nadir, while significantly speeding-up the realization of steady-state goals. Stability proof and steady-state analysis are developed. Comparative case-studies with state-of-art controllers, as well as with traditional SCADA systems, are conducted to evaluate the performance and robustness of the proposed controller under different scenarios, including: loading variation, communication failure, loss of generation, and plug-and-play capacity. Results showcase the proposed controller ability to significantly improve islanded microgrid regulation.

基于D-PMU的孤岛微电网DER的分布式电压和频率控制

为了改善孤岛微电网中分布式能源（DER）的频率和电压调节，本文提出了一种基于分布级相量测量单元（D-PMU）监视的新型分布式控制范例。首先，提出了一种新的策略，称为同步相量聚合。该策略利用了D-PMU提供的高分辨率，低延迟和带时间戳的同步测量，以在系统动态过程中获得DER稳态工作条件的本地预知。基于此信息，开发了新颖的基于测量的控制包，以提供发电机贡献的稳定和校正调整。这些控制器能够有效改善DER的动态性能，例如，抑制振荡，超调和频率最低点，同时大大加快了实现稳态目标的速度。开发了稳定性证明和稳态分析。进行了与最先进的控制器以及传统SCADA系统的比较案例研究，以评估所提出的控制器在不同情况下的性能和鲁棒性，包括负载变化，通信故障，发电损耗和插头播放能力。结果显示了拟议的控制器功能，可以显着改善孤岛微电网的监管。进行了评估，以评估所提出的控制器在不同情况下的性能和鲁棒性，包括：负载变化，通信故障，发电损耗和即插即用能力。结果展示了拟议的控制器功能，可以显着改善孤岛微电网的监管。进行了评估，以评估所提出的控制器在不同情况下的性能和鲁棒性，包括：负载变化，通信故障，发电损耗和即插即用能力。结果展示了拟议的控制器功能，可以显着改善孤岛微电网的监管。
