| Abstract: |
| The multi-step high-order Taylor series method of transient stability calculation is studied. The principle of its optimal integral scheme is proposed：when the step，order and precision are determined，some weight coefficients may be set as zero according to the calculation load and the others be figured out according to the requirements of algorithm for convergence and stability. The proposed principle is applied to design the 2-step 2-order optimal integral scheme and case study shows that，compared to the general multi-step high-order method or the single-step high-order method，its stability and speed are enhanced. |
