Today, advancements in relaying capabilities offer several alternatives such as the centralization of protection and control and the digitization of secondary systems. Distribution system operators (DSOs) must ensure a delicate balance between maintaining system stability and accommodating the diverse interests of stakeholders, including independent power producers (IPPs) and end consumers, who demand an uninterrupted power supply with high-quality parameters. Originally, these systems operated radially to carry power from the substation to the end users. However, increasing penetration of inverter-based DERs (IBDERs) is. Quantum communication represents a paradigm shift in secure information transmission, leveraging the fundamental principles of quantum mechanics to achieve theoretically unbreakable encryption. The field emerged from the convergence of quantum physics and information theory, with quantum key. Zurich, August 19, 2024 – Today, Hitachi Energy achieved another milestone in extending its distribution automation offering with the launch of the Relion REF650 multi-application protection and control relay, specifically designed for medium-voltage power distribution grids.
