中文摘要
在直流配电网络中,大量分布式资源以互联微网形式接入,以挖掘信息物理融合下的资源调节潜力。然而,物理不确定性(如出力波动)与信息不确定性(如通信拥塞)易叠加引发严重的有功功率波动。为此,分别从微网层和资源层研究基于信息物理跨空间认知与协同的有功功率控制方法。针对微网层,提出依赖潮流约束的集中式控制方法生成最优指令,并设计需求驱动的网络匹配机制保障通信可靠性;针对资源层,提出组合式容错控制策略以应对外部扰动,并设计双层优化策略支持即插即用场景下的多场景灵活调控。最后通过算例验证所提方法的有效性。
English Abstract
In the DC distribution network, massive distributed resources are connected as networked microgrids to exploit the regulation potential of resources under cyber-physical fusion. However, it cannot be ignored that physical uncertainties, such as generation fluctuations, and cyber uncertainties, such as communication congestion, will easily be superimposed to cause severe active power fluctuations. To address these issues, active power control based on cyber-physical cross-space understanding and cooperation is studied for microgrids and resources, respectively. For microgrids: 1. Considering the multifaceted factors in regulation, the power flow constraints-dependent centralized control method is studied to generate the optimal control commands; 2. Considering the need to build a wired network for microgrids to ensure communication quality, a demand-driven network matching method is designed to provide reliable network support. For resources: 1. Considering the presence of external disturbances in the regulation process, a combinatorial fault-tolerant control strategy is proposed to tolerate faults actively and achieve a flexible response of resources to microgrids' commands; 2. Considering the need to build a wireless network for flexible communication under plug-and-play of resources, a dual optimization strategy is proposed to provide reliable network support for multi-scenario regulation. Related case studies are presented in the final.
