virtual private cloud based power dispatching automation system architecture and application
IEEE Transactions on Industrial Informatics, 2019Co-Authors: Dongxu Yang, Hua Wei, Yun Zhu, Jian-cheng TanAbstract:This paper presents the framework of a power-dispatching automation system (PDAS) based on a virtual private cloud, which extracts advantages of technologies, such as a virtual private cloud, a virtual private network, an https protocol, etc. Unlike existing on-premise or public cloud hosted PDASs that are vulnerable and may be subject to blackouts due to extreme conditions, such as natural disasters or cyberattacks, the proposed framework operates more safely and securely under those conditions, while at the same time meeting the reliability requirements for power systems as well. This paper presents the theory, architectural design, characteristics, and implementation process of the system, as well as its reliability and cyber security measurements. The annual failure time of the proposed system is reduced from 61.2 to about 0.43 min, about 142 times less than those of existing PDASs. This framework has been implemented in the Lipu power system in China since May 2016. Results show that the proposed system is reliable, safe, and cost-effective, with a bright prospect for future applications.

wavnet wide area network virtualization technique for virtual private cloud
International Conference on Parallel Processing, 2011Co-Authors: Weida Zhang, Luwei Cheng, Choli WangAbstract:A virtual private cloud (VPC) is a secure collection of computing, storage and network resources spanning multiple sites over Wide Area Network (WAN). With VPC, computation and services are no longer restricted to a fixed site but can be relocated dynamically across geographical sites to improve manageability, performance and fault tolerance. We propose WAVNet, a layer 2 virtual private network (VPN) which supports virtual machine live migration over WAN to realize mobility of execution environment across multiple security domains. WAVNet adopts a UDP hole punching technique to achieve direct network connection between two Internet hosts without special router configuration. We evaluate our design in an emulated WAN with 64 hosts and also in a real WAN environment with 10 machines located at seven different sites across the Asia-Pacific region. The experimental results show that WAVNet not only achieves close-to-native host-to-host network bandwidth and latency, but also guarantees more effective VM live migration than existing solutions.

power television and tele dialogue system based on virtual private cloud
2020 4th International Conference on Power and Energy Engineering (ICPEE), 2020Co-Authors: Shaojun Yang, Hua Wei, Shengchao Qin, Le ZhangAbstract:This paper proposes a power television and tele-dialogue system architecture based on the virtual private cloud. The architecture uses HTML5 technology to replace NPAPI plug-in technology, which eliminates the network security threats caused by the defects of NPAPI plug-ins, and dramatically improves the security of the system. With the help of technologies such as WebRTC and WebSocket, real-time communication of the browser is realized, the waste of terminal equipment and server performance is reduced, and the security of data transmission is improved. Compared with the traditional system architecture, the average total connection time of this system is only 10.912%, which significantly reduces the response time of the system. The proposed architecture promotes the power dispatching system from the traditional four to the current six types of “tele-” functions and gives better play to the role of cloud dispatching system in power production, operation, and management.

A WeChat-Based System of Real-Time Monitoring and Alarming for Power Grid Operation Status under virtual private cloud Environment
Complexity, 2020Co-Authors: Chunjie Lian, Hua Wei, Xiaoqing Bai, Zhongliang LyuAbstract:The existing power grid alarm system using SMS (SMSAS) is complex and suffers some problems such as high latency in data transmission, low reliability, and poor economy. For solving these problems, this paper proposes a WeChat-based system under the virtual private cloud environment to achieve real-time monitoring and alarming for the power grid operation status (WMAS). For WMAS, the WeChat mini program (WMP) is adopted, and it has the dedicated data channel using the Https protocol, which is set up in the WMP and the web API to encrypt the data content to ensure the integrity of the data. Combined with virtual private cloud technology, the hardware resources are virtualized, and the proposed system has strong disaster recovery capability, which significantly improves the flexibility and reliability of the system. Compared with SMSAS, our simulation shows that the time from sending to receiving the information in the proposed system is reduced from 4.9 seconds to 172 milliseconds, with the latency reduced by 28 times. On the contrary, the reliability of the proposed system is as high as 99.9971%, and the annual failure time is 15.24 minutes, which is 380 times lower than 96.51 hours of the SMSAS. The proposed system has been implemented in the Lipu power system in Guangxi, China. More than one year of stable operation indicates that the proposed system is safe, reliable, flexible, and convenient with a bright prospect for future applications.

wavnet wide area network virtualization technique for virtual private cloud
International Conference on Parallel Processing, 2011Co-Authors: Weida Zhang, Luwei Cheng, Choli WangAbstract:A virtual private cloud (VPC) is a secure collection of computing, storage and network resources spanning multiple sites over Wide Area Network (WAN). With VPC, computation and services are no longer restricted to a fixed site but can be relocated dynamically across geographical sites to improve manageability, performance and fault tolerance. We propose WAVNet, a layer 2 virtual private network (VPN) which supports virtual machine live migration over WAN to realize mobility of execution environment across multiple security domains. WAVNet adopts a UDP hole punching technique to achieve direct network connection between two Internet hosts without special router configuration. We evaluate our design in an emulated WAN with 64 hosts and also in a real WAN environment with 10 machines located at seven different sites across the Asia-Pacific region. The experimental results show that WAVNet not only achieves close-to-native host-to-host network bandwidth and latency, but also guarantees more effective VM live migration than existing solutions.
