In recent years, residential and fielding photovoltaic generation systems are rapidly and massively connected to the distribution system in Japan. In addition, electric vehicles are gradually widespread, and there is a possibility that they will be introduced rapidly in the future. Furthermore, aggregators and Virtual Power Plant (VPP) operators will appear in the future, there is a possibility of collectively controlling them. Due to this influence, reliable voltage management and power flow management are becoming difficult, and technical development is becoming necessary.On the other hand, distribution system in Japan in recent years, line sensors are being installed in order to measure the voltage and power flow at each point distribution, and the introduction of a system that can monitor the state of the power distribution system in real time is progressing. We are also developing analysis tools that can simulate the state of the distribution system in detail. In addition, the progress of IoT technology is rapidly progressing, and methods of applying it to grid technology are proposed.In this paper, we describe the state of development of technology to apply the concept of digital twin proposed in the IoT technology to the operation and control in the distribution system, and the future development.
