Power Systems Lab
Machine-translated · View original
The lab designs power systems that make the best use of renewable energy.
AboutAbout the lab
Delivering electrical energy economically and reliably.
The Power Systems Lab studies technologies for generating and delivering electrical energy effectively, economically, and stably.
It approaches power systems from many angles, including software, hardware, and systems perspectives.
In recent years, the lab has been developing technologies for making use of renewable energy generation such as solar and wind power.
Its research themes range widely, from hydrogen energy and microgrids to power trading between consumers.
Key terms
- Renewable energy
- Energy that can be obtained repeatedly from natural forces, such as solar and wind power. The amount of power generated varies with the season and the weather
- Microgrid
- A small power grid that manages the supply and demand of electricity and energy within a relatively small area, such as a district or city block
- Consumer (electricity customer)
- The side that buys electricity from a power company and uses it, such as ordinary households, factories, and buildings

*Illustrative imageHydrogen Energy
Because the output of renewable energy depends on the weather, storing surplus electricity by converting it into hydrogen is being considered. The lab studies how to resolve the remaining issues of cost, efficiency, and safety at each stage: producing, storing, transporting, and using hydrogen.
*Illustrative imageSector Coupling
The lab considers that shared electric vehicles can carry not only people and goods but also electric power. It plans delivery routes together with energy management of groups of microgrids, and studies how to move electric power across time and space.
*Illustrative imagePeer-to-Peer (P2P) Power Trading Between Consumers
A model in which consumers exchange electricity directly with each other, without going through a power company, is being considered. Assuming a framework that gives participating consumers economic benefits, the lab evaluates the advantages that such trading brings and studies mechanisms for determining trading prices.
*Illustrative imageAI-Based Generator Operation Planning
Deciding which generators to run and when, so that the total of fuel, start-up, and maintenance costs is minimized, is called unit commitment (generator start-stop scheduling). The lab applies AI to this problem to achieve more economical operation.
