Abstract
A novel model for on-line dynamic congestion management (DCM) under transient stability constraints is proposed. The DCM is modeled as a nonlinear programming problem to minimize the total adjusting cost in purchasing power. Based on the optimal control principle, the transient stability constraints and power transmission limitations are all represented by linear inequality constraints of generations. A case study of DCM is performed on the New England 39-bus test system. By comparison of the test results of the proposed model and a static congestion management method, it is validated that the proposed model is efficient in managing dynamic congestions and ensuring the security of power system operations.
