This series of seminars is motivated by the need to hear from leaders in academia, government, and industry about major problems and opportunities in these rapidly changing systems. The talks vary from the big picture holistic presentations to the focused open R&D questions that must be addressed in order to simultaneously enable decarbonization and ensure high-quality service during normal conditions. As extreme events become more frequent, it is necessary to provide service without experiencing major widespread blackouts. The challenge of localizing the effects caused by triggering events by means of cooperative participation of diverse end-users with their many innovative hardware and software solutions, in coordination with system operators creates many open questions. Similarly, innovation for enabling end-to-end integration of novel resources, demand response, grid control, storage becomes essential for decarbonization. The emphasis of this series is on the systems aspects of these challenges and the opportunities offered by transforming today’s architectures that support flexible, seamless end-to-end participation of the large number of grid users.
