Abstract: To integrate the growing amount of renewable resources in the grid, power system operation problems are increasing in size and complexity. In recent years, machine learning or AI-based approaches have gained significant attention both in academia and industry. A main challenge in adopting these algorithms arises from the constraints in power system problems, which are hard limits that must be satisfied at all times. Tools like neural networks, can limit their outputs to be in simple regions, but there is no obvious way of forcing complex constraint satisfaction at the output. In this talk, we show a neural network architecture that guarantees constraint satisfaction by construction, without relying on steps like projections. By exploring the interior of the feasible set, we demonstrate improved efficiency and closed-loop performance for optimal power flow and model predictive control problems.
