Popis:	In general, conventional Optimal Power Flow(OPF) solutions utilize some optimization techniques at a single case. In the OPF solution method, all the available variables are used to solve the problem. In practical operation, such a solution is not a practical consideration because the control actions would be too many to be implemented. In this paper, sensitivity factors combined with dynamic programming technique are used to solve short term (one day) dynamic optimal power flow. A two-step real time real power dispatch method considering inconforming load change is used to solve real power dispatch, and then, the sensitivity factors are used to solve reactive power dispatch with some constraints. Finally, the dynamic programming technique is used to minimize the control actions to as little as possible. The advantages of this method are simple and easy to implement, and it would greatly enhance the operators' planning.
