| Abstract: | The dynamic security region (DSR) method is a new approach to transient stability analysis of power systems. Compared with the pointwise approach, the new method is more helpful to control strategy of transient stability and the security assessment of the systems with load uncertainty. An analytical expression for the transient stability security region (TSSR) has been derived using a classical model of power systems. A prediction-correcting method based on the hybrid approach for the evaluation of generator power output limit and the TSSR has been developed. Calculation examples have been obtained on a 3-machine 7-nodes bus test system, and the important properties of TSSR are given. |
