Study on the Calculation of the Optimal Power Operation Considering Line Contingencies

상정사고를 고려한 전력계통 최적운용에 관한 연구

The power system scheduling process is formulated as an optimization problem with linear inequality constraints. AC Loadflow method is used for the problem solution and line losses are considered. The constraints under consiceration are generator power limits, load schedding limits and line capacity limits. In solving the objective function the Dual Relaxation method is adopted. Tests indicate that the method is practical for real time applications.
