Abstract	The trend toward deregulation has posed more challenging requirements on the traditional scheduling models, e.g. incorporating transmission components in the dynamic economic dispatching (DED) and introducing time-related constraints in optimal power flow (OFF). In this paper, the authors describe an algorithm for the integrated DED/OPF problem. Both time-separated (including full AC network constraints: voltage, angle, reactive power and branch flow etc.) and time-related constraints are considered and combined in a single optimization problem which is solved by a direct nonlinear interior point method (IPM). A border blocked system is derived and further decomposed into time-separated sub-matrices whose sizes merely rely on network sizes and 4*4 block structure is the same as the node admittance matrices. Hence, the Newton OPF techniques can be fully utilized. The numerical examples that range from 30 to 118 bus system with up to 24 hour periods have shown the proposed method is a very promising optimization tool for the emerging power market.
