Facilities planning technologies using graph structured deep reinforcement learning

Uses AI to reduce maintenance and renewal costs for electric power system facilities.


  • A reinforcement learning approach that can be applied to capital investment planning and other cost minimization problems. Input data on optimization targets with complex structures into original graph neural networks to learn models using deep reinforcement learning frameworks and resolve reward maximization (cost minimization) problems.

Applications



  • Create facilities renewal plans for electric power systems

Benchmarks, strengths, and track record



  • In numerical experiments using model systems, confirmed 10% reductions in capital investment costs + maintenance costs compared with Monte Carlo simulations.
