| Abstract: |
| To deal with the high dimensionality and computational density of the Optimal Power Flow model with Transient
Stability Constraints (OTS), a credible criterion to determine transient stability is proposed based on swing curves
of generator rotor and the characteristics of transient stability. With this method, the swing curves of all generator
rotors will be independent one another. Therefore, when a parallel computing approach based on the MATLAB
parallel toolbox is used to handle multi-contingency cases, the calculation speed is improved significantly. Finally,
numerical simulations on three test systems including the NE-39 system, the IEEE 300-bus system, and 703-bus
systems, show the effectiveness of the proposed method in reducing the computing time of OTS calculation. |
