【摘要】：智能电网背景下的孤岛微网是典型的信息物理系统(CPS),在面对通信安全威胁、需求侧主动参与控制、分布式电源"即插即用"等新问题时,需要拓展传统的信息物理融合思维,开发不完全依赖于中央控制器的协同技术。基于此,提出了含有以频率为触发信号的需求侧单元、可再生能源发电、柴油发电及电池储能单元的孤岛微网有功控制模型。提出了一种完全分布式的协同控制方法使系统能以经济最优的方式实现频率的快速恢复,分为一致项、频率反馈和反馈系数设定这3个部分。其中一致项控制各发电单元遵循等微增率准则运行,频率反馈控制系统频率的快速恢复,计及了全局感知信息和误差校对信息的反馈系数,提高了系统的控制性能。仿真算例验证了所述模型与方法的有效性与可靠性。
[Abstract]:The island microgrid in the context of smart grid is a typical information physical system. In the face of communication security threats, demand-side active participation in control, distributed power "plug and play" and other new problems, we need to expand the traditional thinking of information physics fusion. Develop collaborative technologies that are not entirely dependent on central controllers. Based on this, the active power control model of isolated island microgrid with demand side unit, renewable energy generation unit, diesel power generation unit and battery energy storage unit with frequency as trigger signal is proposed. A fully distributed collaborative control method is proposed to enable the system to achieve fast frequency recovery in an economical and optimal manner, which is divided into three parts: consistent term, frequency feedback and feedback coefficient setting. Among them, the consistent item controls the operation of each generating unit according to the equal micro-increase rate criterion, and the frequency feedback control system can recover the frequency quickly. The feedback coefficient of global perceptual information and error proofreading information is taken into account, and the control performance of the system is improved. The effectiveness and reliability of the proposed model and method are verified by simulation examples.
