Japan has been gradually liberalizing its electric power market since the 1990s. In April 2020, power generation and power transmission were legally separated as the final stage of the three-stage electric power system reform that began in 2015. Since the number of distributed energy sources (including renewable energy sources) will continue to rise, there is a need to develop individual fundamental technologies for distributed energy sources. It is also necessary to create more secure, more resilient systems to smooth the public implementation of said technologies and support the electricity market.

Our research focuses on peer-to-peer (P2P) trading of electricity between prosumers who possess distributed power sources such as solar power generation systems. We will construct and test a system to conduct virtual P2P electricity trades on the Tokyo Tech campus. Using the data we acquire through these virtual trades, we will analyze aspects such as electricity trading platforms, prosumer behavior and price trends. Based on the insights we gain, we will pursue technical development collaborations from the viewpoint of the electricity trading market.
