Popis: | In this paper, an interval programming based optimal power flow model is proposed to consider the interval uncertainty of wind power in the operation of hybrid AC and DC power systems. In the proposed model, the prediction error of the wind power and the uncertainties of the realistic limits of the branch flow are treated as interval numbers. Also, both the post-contingency short-term and long-term security operation are considered to achieve a more secure power system operation by the fast control of voltage source converters. The proposed uncertain optimization model is transformed into a deterministic optimization one by using the interval order relationship conversion. Finally, the proposed model is validated by the simulations on the modified IEEE 14-bus system. |
