智能电网信息物理系统（CPS）利用各种物理组件来提供对电网的更好了解和精细控制，同时通过集成先进的通信技术来传输巨大的数据量。为了更好地为智能电网CPS中的应用提供服务，通信网络必须同时考虑提高系统吞吐量和满足实时性的要求。为了解决这一问题，本研究提出了一种新的沟通策略。该策略是基于不同的智能电网CPS应用程序的时间性能特征，它还利用时间和空间的可用频谱资源，通过频谱共享技术进行传输。最后，以IEEE 14节点系统为例，验证了该方法的有效性。一个重要的实时应用，即实时电压稳定性的提高，已经在案例研究中进行了研究。实验结果表明，该通信策略能够提高智能电网CPS的吞吐量和时间敏感应用的时间性能。
Smart grid cyber-physical system (CPS) exploits various physical components to provide better knowledge and delicate control of the power grid, while the huge data volume is transmitted via the integration of advanced communication technologies. To provide better services for the applications in the smart grid CPS, the communication network has to consider the aspects of both improving the system throughput and meeting the real-time requirement. In order to address this issue, a new communication strategy is proposed in this study. The strategy is based on the time performance features of different smart grid CPS applications, which also exploits both temporal and spatial available spectrum resources for transmitting via spectrum sharing techniques. Moreover, the performance has been verified by a case study based on IEEE 14-bus power system. An important real-time application, namely real-time voltage stability enhancement, has been investigated in the case study. Results show that the proposed communication strategy is able to improve the throughput of the smart grid CPS and the time performance of time sensitive applications.
