Abstract

This paper proposes a new concept named Flexible, Reliable and Intelligent ENergy Delivery System (FRIENDS) as a future power distribution system. In FRIENDS, new facilities called Quality Control Centers (QCCs), which consists of Voltage Control type Inverters, Distributed Generators (DGs), Energy Storage Systems (ESSs), etc., are installed between distribution substation and customers. By controlling and operating those inverters and DGs in QCCs adequately, balancing the supply and demand can be realized. Particularly, when the power supply from the transmission network is interrupted, isolated local network which consists of some QCCs are composed in order to realize uninterruptible power supply. In the isolated network, the DGs and ESSs in QCCs are employed as backup generators. This paper proposes a distributed and autonomous method for balancing the power system supply and demand during interruption period. This paper also investigates the effectiveness of the proposed method through computational simulations using MATLAB and LabVIEW. The results obtained using our hardware with MATLAB and LabVIEW were also compared with that of the one obtained using PSCAD.

电力系统平衡使用朋友

本文提出了灵活、可靠、智能的能源输送系统(FRIENDS)作为未来配电系统的新概念。在FRIENDS，被称为质量控制中心(QCCs)的新设施，由电压控制型逆变器、分布式发电机(dg)、储能系统(ess)等组成，安装在配电变电站和客户之间。通过充分控制和运行qcc中的逆变器和dg，可以实现供需平衡。特别是在输电网供电中断的情况下，采用由若干个qcc组成的隔离局域网络来实现不间断供电。在隔离网络中，qcc中的dg和ess作为备用发电机。本文提出了一种分布式、自治的电力系统中断期供需平衡方法。本文还通过MATLAB和LabVIEW的计算仿真验证了所提方法的有效性。用MATLAB和LabVIEW对硬件进行了仿真，并与PSCAD进行了比较。
