Aiming to illuminate the path towards integrating energy harvesting (EH) technologies into modern electric power systems, thereby enabling more efficient and sustainable energy solutions, this paper explores energy harvesting within electric power systems and points out its potential to power data communication purposes. In this sense, we examine the overarching principles of EH in these systems, spotlighting both the merits and limitations associated with energy extraction across varying voltage levels and electric signal frequency bands. Central components of EH devices, alongside a spectrum of harvesting methodologies, are thoroughly reviewed. Also, we showcase a case study that provides a quantitative assessment of EH potential in electric power systems. The manuscript culminates in a forward-looking analysis of EH, considering emerging technologies that promise to redefine the landscape. These include integrating hybrid power line and wireless systems, strategies for optimal power allocation, enhancements in physical layer security, the innovative concept of negawatts, advancements in harvesting circuit designs and applying non-orthogonal multiple access techniques

“…In [110], this technology was implemented to deliver 20 W of power to online monitoring sensors with the application in smart grids and with a charging distance of 1.1 m in a 110-kV HV line and efficiency of 20.2%. An HV insulator string with WPT capability was designed to harvest energy from the magnetic field of AC power lines and transmit power to online monitoring sensors using the domino-resonant concept, in which coil-resonators were embedded in insulator discs to transfer power between ends of the insulator structure [111,112].…”

HVDC transmission systems are becoming more prevalent because of the advantages they offer. They are more efficient and environmentally friendly and are becoming preferred in distributed power generation. The reliable operation of HVDC transmission lines requires distributed, online monitoring, which is not as well-developed as those in an HVAC system. The advancement of HVDC systems will require online monitoring that provides information on the operating and environmental conditions, mechanical stress on the conductors and the structure, vegetation clearance, and security of the system. This perspective paper provides a thorough overview of the state-of-the-art technologies that are applicable to the monitoring of HVDC transmission lines. The challenges and future direction in the development of sensors for HVDC applications are highlighted. One of the key challenges unique to HVDC transmission lines is energy harvesting from the transmission line conductors to provide power for the monitoring equipment. This paper reviews the potential technologies for energy harvesting from HVAC transmission lines and their suitability for employment in HVDC transmission lines.

“…Also, another option could be the use of a coupled electric motor and electric generator by means of an insulated shaft (one device on the platform and the other at ground level). Finally, some proposals of magnetic power transfer can be found in [24], [25] which are based on dominoresonators, and they could also be considered to transmit low power levels.…”

Power Flow Controllers (PFCs) or Current Flow Controllers (CFCs) are expected to be required in future High Voltage Direct Current (HVDC) grids to aid in the current distribution. This work analyses the feasibility of this kind of devices from the implementation point of view. First, the needs of a PFC as a medium voltage converter floating at high voltage are assessed. Then, the paper discusses the challenges to implement one of these converters, such as the sizing of the power electronic elements, cooling management, insulation from ground, etc. Most of them are already tackled in other existing devices in the field of high voltage. Powering the PFC semiconductors gate-drivers and other auxiliary systems at high potential is seen as a particular point to take into account when building the device.
