## 2 Power Communication Network and Its Information  
As one of the largest physical networks of the power companies, the electric power communication network carries the core business of power grid operation and enterprise management, and is an important guarantee for the security, stability and economic operation of the grid. With the development of these years, great progress has been made in the construction of the SG system. However, in the era of increasing network information, power information system will contain more contents. Paper [6] proposed to integrate the current power private network with the ubiquitous power Internet of Things (IoT) to form a power physics and social information system. It will bring more challenges to make full use of data including social factors to improve the openness of the power communication network. As a cyber-physical system (CPS) in the energy field, SGs require designers to take into account social, physical, and informational elements. In other words, while deeply integrating physics and information, it also takes into account the influence of social factors such as risky behavior among decision makers in the electricity market on the SG.  
As shown in Figure 1, after incorporating data related to social factors into the electric power communication network, the integrated energy system will combine the two advantages of high reliability of the SG and the openness of the human-machine-Internet of Things. Therefore, among current smart grid construction requirements, IoT is planned to be considered as part of the public network for access through private power networks. At the same time, the access of distributed energy sources makes the data sources in the power communication network more complicated. Meanwhile, other forms of energy information, such as heat and natural gas, can also be accessed through a dedicated power network, thereby forming a smart energy system that uses electricity as its main energy source.  
After the SG and the ubiquitous Internet of Things merge into the power CPS, different information networks can be accessed to the power private network. The influx of heterogeneous data not only makes the processing of information more difficult, but also brings greater challenges to the communication security of the private network. This requires that the unauthorized data from the public network must satisfy the internal network security information standards before it is allowed access to, which are able to ensure the information security of the intranet. In the face of the above problems arising from the integration of the Internet and the private network, it is proposed to establish a data virtual platform to aggregate the power data received from the underlying interface on the virtual platform. The platform can convert heterogeneous data transmitted by different protocols into a unified format and avoid the multiple development of technicians in advanced applications. At the same time, it also has the development potential of embedded security mechanism. It can securely clean and encrypt data entering the internal network, and reduce the risk of intrusion from data traffic and data interaction.
