Abstract
Power flow in an electric power network is optimized during multiple time periods of operation of the electric power network by solving an optimization problem represented by an objective function by first initializing variables and constraints of a branch and bound (BB) tree, wherein nodes in the BB tree represent feasible regions of the optimization problem. Upper and lower bounds on the objective function are solved using the BB tree. A lowest upper bound and a lowest upper bound are updated. If difference between the lowest lower bound and the lowest upper bound is less than a threshold, the power flow is outputted based on the lowest lower bound and the lowest upper bound.
