This conference paper presents a selection of best practice examples from the ISGAN Annex 6 case book, focusing on the development of smarter and stronger electricity transmission and distribution systems. It highlights how different countries are addressing the challenges associated with integrating renewable energy sources, maintaining system stability, and ensuring reliable power supply. The document illustrates a range of technological solutions, including advanced monitoring systems, high-voltage direct current (HVDC) technologies, flexible AC transmission systems (FACTS), and smart voltage control, demonstrating their role in enhancing grid flexibility and performance. Through real-world case studies—from Europe, the United States, Africa, and beyond—the publication showcases how innovations can be applied across different levels of the power system, from large-scale transmission networks to local distribution grids and end-user engagement. It also emphasises the increasing importance of digitalisation, data sharing, and interoperability in enabling more efficient and resilient grid operation. In addition, the paper highlights the evolving role of consumers, who are becoming active participants in energy systems through demand response, distributed generation, and new market mechanisms. Overall, the document provides valuable insights into practical solutions and lessons learned from international experience, supporting policymakers, system operators, and stakeholders in advancing the transition towards more flexible, secure, and sustainable electricity networks.
