The lab studies energy systems toward a carbon-neutral society.

AboutAbout the lab
Toward a safe, secure, and prosperous carbon-neutral society
Matsuhashi-Mae Lab studies the entire energy system, including power systems, from the perspective of electrical engineering.
The lab aims to realize a safe, secure, and prosperous carbon-neutral society, covering global warming countermeasures and energy policy as well.
In the energy field, the lab believes it is important to achieve "S+3E": stable supply, economic efficiency, and environmental compatibility, all on the premise of safety.
Research themes are decided by respecting students' wishes as much as possible, within the bounds of the department's and the lab's policies.
Key terms
- Carbon neutrality
- The idea of balancing the emissions and the absorption of greenhouse gases such as carbon dioxide so that the net amount is zero
- S+3E
- An approach to energy that, on the premise of Safety, seeks to satisfy three Es at the same time: stable supply (energy security), economic efficiency, and environmental compatibility
- Bounded rationality
- The idea that, because people have limited information and limited capacity for judgment, they do not always make the choice that is most beneficial to them
ResearchResearch themes
The lab conducts diverse research from the perspective of electrical engineering on entire energy systems, including power systems, as well as global warming countermeasures and energy policy. Taking institutional reforms and developments in new technologies into account, it works to advance innovation in energy systems.
*Illustrative imageEnergy Research Reflecting Institutional Reforms and New Technologies
The lab tackles challenges in energy systems in light of institutional reforms, such as retail liberalization of electricity and gas and the unbundling of power generation and transmission, and new technologies related to smart grids, while also considering changes in consumer behavior in response to energy-saving measures.
*Illustrative imagePower Generation Mix and Energy Economy Models
The lab develops a power generation mix model that takes expanded deployment of renewable energy into account, and builds a new energy economy model that incorporates bounded rationality. It then integrates the two models to advance its research.
*Illustrative imageDesign and Control of Sustainable Systems
This research seeks to optimally balance the trade-offs among stability, efficiency, and environmental performance, on the premise of safety. Its core is methodology for system design, control, and optimization, ranging from the control of industrial equipment to the optimization of energy systems.
