Given the increasing share of variable renewable energy resources (VREs), power system operations need to account for associated uncertainty with a fine resolution. This paper formulates an adaptive robust optimal flow, which secures hourly schedule against uncertain intrahour injections. The is characterized by spatially correlated polytopic sets. Second-order cone programming relaxation emplo...

Under the competitive environments, power companies may calculate optimal power flow (OPF) in many occasions: especially for such real time applications as contingency analysis and congestion management. However, caused by congestions, etc., it is not guaranteed that OPF has the feasible solution in every calculation case. This paper proposes a new optimal power flow calculation model applicabl...
