Professor Jun-ichi Imura of Tokyo Institute of Technology and others have developed a technology that can maintain a well-balanced power supply and demand using the latest technology called section prediction with reliability.This makes it possible to respond to changes in power generation due to changes in the weather.

 Incorporating renewable energy in a well-balanced manner in addition to thermal power generation and nuclear power generation will enable stable power supply and demand while reducing the burden on the environment and costs.However, among renewable energies, photovoltaic power generation, which has been attracting particular attention in recent years, has the problem that the power generation efficiency varies greatly depending on the amount of clouds on that day.If the ratio of solar power generation is increased in the future, how to make up for this fluctuation will become a big issue.

 Therefore, it is important to predict the amount of solar power generation in advance and increase the amount of other power generation accordingly.The group used a technique called confidence interval prediction to enable such predictions.Prediction with confidence can be used to predict the expected amount of solar radiation and its reliability over time.In other words, it turns out that the amount of solar power generation can only generate this much at worst, and it is possible to predict in advance the amount that will need to be supplied from other power sources.

 Prediction interval with reliability is a method that is becoming the mainstream in the world in forecasting power generation of renewable energy.In the future, in addition to these predicted values, we aim to build a system that derives the optimum operation method for the entire power supply system while taking into account the cost of starting and stopping thermal power generation.

Tokyo Institute of Technology

The pinnacle of science and engineering university that continues to produce science and engineering people with high aspirations and a Japanese spirit, mastering the knowledge that creates the times, refining their skills

Tokyo Institute of Technology was established as the Tokyo Institute of Technology in 1881 (Meiji 14), when modernization of industry was an urgent need.Since its establishment, it has continued to produce excellent research results with excellent science and engineering human resources, and is still at the top of Japan's science and engineering universities.Tokyo Institute of Technology requires not only a high degree of specialization but also liberal arts […]
