The main themes of the two 2025 CIGRE symposia, “Changes Needed in the System for the Energy Transition” (Trondheim, May) and “Grid Enhancement, Strategic Planning, Technological Innovation, and Climatic Adaptation for a Resilient Future Energy System” (Montreal, September), clearly highlight the critical importance of technological innovation and energy transition in the electrical sector.Read More

he increasing number of Renewable Energy Resources (RES), and other installations, like energy storage, connected via converters, has given raise to concerns about the performance of the different protection and automation functions. Installations connected to the electric network with power electronic based converters are also known as Inverter Based Resources (IBR).Read More

The growing electrification of demand in the energy transition is driving the expansion of power electronics interfaced demand, and in particular new types of loads such as electrolysers, mega-chargers for electric vehicles and large data centres. These installations are increasingly influencing the behaviour and dynamics of the overall power system and pose unprecedented challenges to the grid. Today, the planning, connection, operational impact and technical behaviour of these large-scale demand facilities remain poorly scrutinised, as evidenced by recent experiences and perturbations in system operation in some jurisdictions.Read More
