Network Virtualization System for Smart Grid Data Acquisition System

Abstract

The smart grid is an intelligent electrical grid system which can enable an interaction between consumer and producer by adapting information technology on power planting, electric power transmission, and power consumption. In this system, consumers and producers can exchange information about the use of electricity in real time. By using this advantage, the consumers can notice the time which has low charges and adjusting the power consumption. Also, the producer can operate electric power supply elastically by supplying the electricity adjusting to the power demand. To achieve this, the smart grid system consists of not only traditional electrical components such as power plant, substation, electrical meter, but also all devices which consume electrical power including TV, refrigerator, IoT devices. As the number of devices grows and the network becomes more complex, the number of packet types in the smart grid system has grown up. Also, the types of data traffic become more varied than before. For example, critical command traffics, use of electricity from the home remote terminal, a large number of sensing data from the IoT devices can be exchanged by the network. However, not all the packet type has the same properties and requirements. In traditional network infrastructure, the administrator should set up a new physical network infrastructure to offer the different network requirements for each type. In this study, we show some benefits of network slicing which can offer different properties corresponding to the type of packets and its importance.
