摘　　要：随着物联网技术的逐渐成熟,智能终端设备的大面积接入是大势所趋,智能终端设备接入后的配电网运行模式亟待研究。首先,研究了配电变压器监测终端(distribution transformer supervisory terminal unit,TTU)在电力系统中的信息采集和通信方式;其次,结合TTU的及时响应和智能处理优势,研究了新型智能配电网的运行模式,建立了智能配电台区运行的分布式自主弹性调度模型;最后,以算例的形式进行了验证分析,证明该调度策略不仅可提升可再生能源的就地消纳水平,而且能够在小概率高风险事件下最大限度保障负荷不间断供电。With the gradual maturity of the internet of things(IoT)technology,the large-scale access of smart terminal equipment is the general trend.The operation mode of the distribution network after smart terminal equipment access is urgently needed for research.This paper first studies the information collection and communication methods of TTU in the power system.Then,combining the advantages of TTU's timely response and intelligent processing,this paper studies the operation mode of the new smart distribution network.Finally,this paper establishes a distributed autonomous resilient dispatching model for the operation of the smart distribution area,and verifies this model in the form of an example.The results prove that the dispatching strategy not only realize the local consumption of renewable energy,but also maximize the uninterrupted power supply of load under small-probability-high-loss events.
