Automatic Blackout Recovery Through a Deterministic Load Flow

The authors have developed AGORA (advanced grid observation reliable algorithms), a deterministic load flow solution that has enabled the development of automatic blackout recovery software for control centers in transmission operators. This restoration system is based on the deterministic, no iterative solution of the load flow equations. The no iterative nature of this load flow does not require an initial point and will execute full computation every time, even at the verge of voltage collapse. Based on this load flow solution, the authors have developed breakthrough technologies for the operation of control centers. The most important breakthrough is the automatic blackout recovery system. This system provides the user with a list of maneuvers (restoration plan) that ensure that the blackout situation will be corrected, and the system brought back to normal operation conditions in the optimal time. This plan guarantees that every maneuver is feasible and will improve the system conditions. This restoration plan is dynamic. The plan will be recalculated if the system is changed or the operator decides to take a different path, both cases invalidating the actual plan
