摘要:

对能源的需求正以前所未有的速度增长,远远高于使用传统和绿色技术的能源发电能力的增长率。特别是,电力行业一直被评为所有其他能源市场中最具活力的增长市场之一。基于可再生能源的分布式(分散式)能源发电是满足如此巨大的能源需求增长的有效和可靠的解决方案[1]。然而,为了管理动态和复杂的分布式系统,必须实时测量、收集、交换和处理大量数据。智能电网管理智能能量输送网络,该智能能量输送网络使能由公用事业公司操作的数据集中器与安装在最终用户处的智能电表之间的双向通信。特别地,动态电网负载和峰值负载管理是通过电网进行双向通信的两个主要驱动力。窄带电力线通信(NB-PLC)和非授权频段(低于1 GHz或2.4 GHz)中的无线通信是用于支持日益增长的智能电网应用的两种主要通信系统。此外,由于NB-PLC和未许可无线链路经历具有显著不同统计的信道和干扰,因此在两个链路上同时发送相同的信息信号显著增强了智能电网通信可靠性。在这篇文章中,我们比较了各种分集合并方案,同时电力线和无线传输。此外,我们开发了一个实时的混合PLC/无线系统的测试平台,以证明通过PLC/无线分集相结合,在一个单一的链路性能实现的性能增强。

英文摘要:

The demand for energy is growing at an unprecedented pace that is much higher than the energy generation capacity growth rate using both conventional and green technologies.In particular, the electric power sector is consistently rated among the most dynamic growth markets over all other energy markets. Distributed (decentralized) energy generation based on renewable energy sources is an efficient and reliable solution to serve such huge energy demand growth [1]. However, to manage dynamic and complex distributed systems, a massive amount of data has to be measured, collected, exchanged and processed in real time. Smart grids manage an intelligent energy delivery network enabled two-way communications between data concentrators operated by utility companies and smart meters installed at the end users. In particular, dynamic power-grid loading and peak load management are the two main driving forces for bidirectional communications over the grid. Narrowband power line communications (NB-PLC) and wireless communications in the unlicensed frequency band (sub-1 GHz or 2.4 GHz) are the two main communications systems adopted to support the growing smart grid applications. Moreover, since NB-PLC and unlicensed wireless links experience channel and interference with markedly different statistics, transmitting the same information signal concurrently over both links significantly enhances the smart grid communications reliability. In this article, we compare various diversity combining schemes for simultaneous power line and wireless transmissions. Furthermore, we developed a real-time testbed for the hybrid PLC/wireless system to demonstrate the performance enhancement achieved by PLC/wireless diversity combining over a single link performance.
