Communication Technologies for Smart Grid: A Comprehensive Survey
With the ongoing trends in the energy sector such as vehicular
electrification and renewable energy, smart grid is clearly playing a more and
more important role in the electric power system industry. One essential
feature of the smart grid is the information flow over the high-speed, reliable
and secure data communication network in order to manage the complex power
systems effectively and intelligently. Smart grids utilize bidirectional
communication to function where traditional power grids mainly only use one-way
communication. The communication requirements and suitable technique differ
depending on the specific environment and scenario. In this paper, we provide a
comprehensive and up-to-date survey on the communication technologies used in
the smart grid, including the communication requirements, physical layer
technologies, network architectures, and research challenges. This survey aims
to help the readers identify the potential research problems in the continued
research on the topic of smart grid communications
LoRaWAN communication implementation platforms
A key role in the development of smart Internet of Things (IoT) solutions is played by wireless communication technologies, especially LPWAN (Low-Power Wide-Area Network), which are becoming increasingly popular due to their advantages: long range, low power consumption and the ability to connect multiple edge devices. However, in addition to the advantages of communication and low power consumption, the security of transmitted data is also important. End devices very often have a small amount of memory, which makes it impossible to implement advanced cryptographic algorithms on them. The article analyzes the advantages and disadvantages of solutions based on LPWAN communication and reviews platforms for IoT device communication in the LoRaWAN (LoRa Wide Area Network) standard in terms of configuration complexity. It describes how to configure an experimental LPWAN system being built at the Department of Computer Science and Telecommunications at Poznan University of Technology for research related to smart buildings
