Japan Looks To Distributed Control Theory To Manage Energy Market Deregulation

Hallie Siegel writes: Japan's power industry is currently centralized, but it aims to deregulate by around 2020. Coupled with this major structural market change, the expansion of thermal, nuclear and renewable power generation will place additional demands on the management of the country's energy market. Researchers from the Namerikawa lab at Keio University are working with control engineers, power engineers and economists to designing mechanical and control algorithms that can manage this large-scale problem.
