EPRI’s new program aims to strengthen grid resilience
The Electric Power Research Institute has launched a global initiative to prepare future grids by modernizing how the electricity-generating sector detects, anticipates, and responds to emerging risks and manages technological transformation. The nonprofit energy research and development organization intends for the initiative, called Rapid Adaptation of Grid Defense, Analytics, and Resilience (RADAR), to provide a scalable framework, advanced tools, and targeted training for strengthening grid resilience and reliability.

Fuel injection by means of solid cryogenic pellets is expected to provide a sound and efficient tool. Hence, the installation of a pellet launching system will be a necessity. Yet, pellets are considered as a serviceable actuator for integrated supplementary functions as, e.g., fast and efficient delivery of seeding gas, or in case needed, the pacing of edge-localized modes. Consequently, a control scheme has to be developed that is capable of mastering the simultaneous actuations covering different tasks. Our scheme relies on pellet launching by a centrifuge accelerator, providing the option for precisely predictable pellet injection sequences. In order to develop a suitable actuator control scheme, as a first step the central part was brought into service at ASDEX Upgrade. It proved operational for feedback particle flux control of a single pellet source. In a subsequent step, it is now upgraded to enable multitasked control of the JT-60SA multipellet source currently under construction. In its finally designated configuration, this control scheme provides a potential solution for a reactor-grade system.
