The IEEE PES ISGT Europe 2026 focuses on the transformation of electric power systems under the pressure of decarbonization, digitalization, and decentralization. The conference will explore cutting-edge developments in smart grid technologies, renewable integration, grid stability, and energy market design. It provides a forum for researchers, industry professionals, regulators, and technology providers to present innovative tools, models, and practices that support the transition to a resilient, flexible, and sustainable electricity system. Emphasis will be placed on interoperability, real-time control, AI-driven solutions, and the evolving roles of utilities, consumers, and prosumers in a multi-vector energy environment.
