Event Overview

Amid growing efforts to achieve a decarbonized society and ensure a stable energy supply, public and policy interest in numerical simulation analysis of power and energy supply-demand systems is rapidly increasing.

This seminar will highlight the latest trends in electricity and energy policy, and introduce cutting-edge analytical methods and practical case studies in the fields of power and energy systems.

Professor Ryoichi Komiyama, our featured speaker, specializes in energy system analysis, energy modeling, and policy analysis. He has been involved in numerous system analyses and policy recommendations in these fields.
In this seminar, he will discuss not only the current state of simulation analysis and its policy implications, but also its potential applications in industry and government.
The event aims to provide practical insights for researchers, policymakers, and professionals working in the energy sector.

The seminar will be moderated by Associate Professor Ken Oshiro from the Faculty of Environmental Earth Science at Hokkaido University.

[About Prof. Ryoichi Komiyama]
Prof. Komiyama received his Ph.D. in Electrical Engineering from the Graduate School of Engineering, the University of Tokyo in 2003.
He previously served as a Senior Researcher at the Institute of Energy Economics, Japan (IEEJ), and held positions as Assistant and Associate Professor at the University of Tokyo before assuming his current role in 2022.
His research focuses on numerical simulation analysis of energy systems and policy evaluation in the fields of energy and environment.

[About the Project and the Seminar Series]
The JST Social Scenario Research Project aims to contribute to the realization of a carbon-neutral society in Japan, emphasizing sustainable development through science and technology. This initiative envisions a desirable future society and explores the pathways, options, and strategies to achieve it. Since April 2023, the project has expanded to integrate knowledge from a broad range of researchers, including those from the humanities and social sciences, fostering further development and societal contribution. A key aspect of the project is the “Social Scenario for Accelerating Carbon Neutral Transition,” focusing on both quantitative and qualitative analyses of carbon-neutral technologies, and developing strategies for societal implementation and system design.

The seminar series with scenario experts is part of this effort, facilitating the exchange of knowledge and strategies to accelerate the transition to a carbon-neutral society.

As part of the webinar series of the Japan Science and Technology Agency (JST) program “Social Scenario Research for the Realization of a Low-Carbon Society,” we held an online seminar on September 9, 2025.

In this seminar, Professor Ryoichi Komiyama, an expert in energy system analysis, energy modeling, and policy analysis with extensive experience in system analysis and policy recommendations, delivered a lecture entitled “Advances in Power and Energy Supply-Demand Analysis: Policy Trends and Prospects for Numerical Simulations”

[Discussion & Q&A]
Discussions focused on the robustness (resilience) of power system operations. It was emphasized that, in addition to optimization results obtained through SCUC/SCED, combining simultaneous feasibility tests (SFT) and reliability assessments is essential for addressing uncertainties. In response to questions regarding whether simultaneous markets and optimization methods might favor specific power sources, particularly nuclear power, it was explained that these approaches are designed as short-term operational optimizations based on marginal costs and are neutral in nature, often prioritizing renewable energy sources with low marginal costs. Furthermore, it was noted that the locational incentives provided by nodal pricing emerge over the medium to long term, and that careful consideration of physical and institutional constraints is necessary.
