Probabilistically Robust AC Optimal Power Flow

IEEE Transactions on Control of Network Systems, 2019
The increasing penetration of renewable energy resources, paired with the fact that load can vary significantly, introduce a high degree of uncertainty in the behavior of modern power grids. Given that classical dispatch solutions are "rigid," their performance in such an uncertain environment is in general far from optimal.
