Nowadays, the smart grid has demonstrated a great ability to make life easier and more comfortable given recent advances. This paper studies the above issue from the perspective of two important and very useful smart grid applications, i.e., the advanced metering infrastructure and demand response using the instrumentality of a set of well-known scheduling algorithms, e.g., best-channel quality indicator, log rule, round robin, and exponential–proportional fairness to validate the performance. To increase the data transmission bandwidth, a new concept of optical wireless communication known as free-space optical communication (FSO) system based on microring resonator (MRR) with the ability to deliver up to gigabit (line of sight) transmission per second is proposed for the two studied smart grid applications. The range between 374.7 and 374.79 THz frequency band was chosen for the generation of 10 successive-carriers with a free spectral range of 8.87 GHz. The ten multi-carriers were produced through drop port of the MRR. The results show up to 10 times bandwidth improvement over the radius as large as 600 m and maintain receive power higher than the minimum threshold (− 20 dBm) at the controller/users, so the overall system is still able to detect the FSO signal and extract the original data without detection.

如今，智能电网已显示出强大的功能，可以根据最近的发展使生活更轻松，更舒适。本文从两个重要且非常有用的智能电网应用的角度研究上述问题，即先进的计量基础设施和需求响应，它使用一组众所周知的调度算法，例如最佳通道质量指标，对数规则，轮循和指数比例公平性来验证性能。为了增加数据传输带宽，提出了一种新的概念，即基于微环谐振器（MRR）的光无线通信新概念，称为自由空间光通信（FSO）系统，该系统能够每秒传输千兆位（视线）传输针对这两个研究过的智能电网应用。范围在374.7和374之间。选择79 THz频带来生成10个连续频谱载波，其自由频谱范围为8.87 GHz。通过MRR的引入端口产生了十个多载波。结果表明，在高达600 m的半径范围内，带宽提高了10倍，并在控制器/用户处保持接收功率高于最小阈值（− 20 dBm），因此整个系统仍然能够检测FSO信号和提取原始数据而不进行检测。
