Robust AC Optimal Power Flow With Robust Convex Restriction

Electric power grids regularly experience uncertain fluctuations from load demands and renewables, which poses a risk of violating operational limits designed to safeguard the system. In this paper, we consider robust AC OPF problem that minimizes generation cost while requiring certain level system security in presence uncertainty. The requires satisfy for all uncertainty realizations within specified set. Guaranteeing robustness is particularly challenging due non-convex, nonlinear flow equations, may not always have solution. work, extend previously developed convex restriction robust restriction , inner approximation non-convex feasible region accounts injections. We then use an algorithm obtains solutions problems by solving sequence optimization problems. demonstrate our its ability control versus operating trade-offs using PGLib test cases.
