Smart Grid Lab
Machine-translated · View original
A lab that links electric power and data to make full use of renewable energy.
AboutAbout the lab
Solving power system challenges with data science.
The Smart Grid Lab researches the development and demonstration of algorithms and models that link electric power and data so that enough renewable energy is available when it is needed.
Renewable energy such as solar power has unstable generation output, so it is difficult to secure enough of it when it is needed.
A smart grid is a next-generation power network technology that aims to make supply more efficient and stable in power systems with a large share of renewable energy.
It grasps electricity usage and generation in real time and uses that data to make effective use of power.
Key terms
- Smart grid
- A next-generation power network technology that grasps electricity usage and generation in real time and uses data to make effective use of power
- Reinforcement learning
- A method used for optimal control of storage batteries. Inference with a trained model is fast, making it well suited to real-time control
- P2P electricity trading
- A system in which people who generate electricity and people who want to use it buy and sell electricity directly with each other within a local area

Renewable energy such as solar power has unstable generation output, so it is difficult to secure enough of it when it is needed. This lab works on developing and demonstrating algorithms and models that link electric power and data so that enough renewable energy can be used when it is needed.
*Illustrative imageOptimal control of storage batteries
As renewable energy spreads, uncertainty in both generation and demand is growing, and flexible control with storage batteries is attracting attention as a key to keeping supply and demand balanced. The lab studies optimal control methods for storage batteries using reinforcement learning.
*Illustrative imageP2P electricity trading using blockchain
This theme covers peer-to-peer (P2P) electricity trading, in which individuals buy and sell surplus electricity from household solar power directly with each other within a local area. In addition to blockchain-based trading, improving processing time and fees and determining prices are treated as separate topics.
