Venue and Participation Options:
The seminar will be conducted both in-person and virtually. Attendees can opt for:

• - Physical Attendance: Kioi Forum, Chiyoda, Tokyo.
• - Live Streaming via Zoom Webinar.
• - Archived Recordings available for two weeks for convenience.

Key Topics to be Discussed

1. The Necessity for System Stabilization in Digital Age

From 13:00 to 14:10, Koichiro Yamaki will highlight the pivotal shift Japan has undertaken in power system development. Historically, Japan improved power supply reliability alongside expanding electrical systems, focusing on synchronizing AC systems and generators. However, with an increasing share of DC transmission and asynchronous generation, this seminar will explore new perspectives on system stabilization. The discussion will not only reflect on the historical transitions within Japan's power grid but also introduce overseas progress in the domain of DC and asynchronous generators.

Key subtopics include:

• - Historical context and evolution of system stabilization.
• - Current international trends.
• - Future expectations for Japan's efforts in system stabilization.
• - Potential utilization of new resources.
• - Strategies to ensure the expectations translate into actions.
• - Q&A session allowing attendees to engage directly with the speakers.

2. Next-Generation Power Grids and Stabilization Technologies

West Nishioka's segment, from 14:20 to 15:30, will discuss the ongoing energy transition and the escalating need for flexibility within the power system due to the rise of renewable energy and the advancement of electrification. This presentation will dissect how innovative solutions like HVDC and enhanced STATCOM technologies contribute to system stabilization. Furthermore, it will address challenges posed by inertia deficiency and domestic discussions surrounding synchronization capabilities.

Key subtopics include:

• - Changes in energy systems and the importance of flexibility.
• - The surge of HVDC technologies and their role in stabilizing the grid.
• - Application of Enhanced-STATCOM in system stabilization.
• - How battery systems can support grid stability.
• - Insights on inertia, synchronization capability, RoCoF, and frequency detection issues.
• - Q&A session providing an interactive platform for feedback and networking.
