In smart grid, a strong communication network plays a very important role, which makes the power grid more controllable and observable. It is a very tough task to study the mutual impact between these two systems due to their different characteristics. This paper proposes a generic and systematic approach for quantitatively studying the impact of communication failures on power grid's measurement...
An ultra high voltage (UHV) ac and dc interconnection will become the foundation of China’s future smart grid. Due to the wide spread of interconnected regions, the distance between control stations will increase dramatically. Therefore, the communication system’s reliability and real-time performance will become increasingly crucial. However, failures of the communication system, such as interruptions,...
With the development of strong and smart grid, power grid and communication system become highly interconnected and mutually dependent. Complex network approach is applied in this paper to describe the interactive characteristics of hybrid power and communication systems in terms of topologies. Qualitative analysis of the impact of communication system on power grid is straightforward. However, quantitative...
SDH communication network is critical for the WARMAP system (a Power System Security and Stability Defense System) which transmits data and control command among different layers of control stations and devices. Figuring out the impact of communication failure on WARMAP will ensure the proper functioning of WARMAP. Firstly, this paper introduces the framework and workflow of WARMAP. And then, through...
