| Abstract: | The principles and algorithms of non-sequential simulation and sequential simulation which are based on the Monte Carlo sampling technique are described. With the two kinds of simulation algorithms,the risk indices are calculated and compared,and an analysis of the convergence and accuracy of the risk indices is also made.The sequential simulation algorithm is suitable for dealing with the time-variant load and constraints and the dynamic process. Appropriate simulation schemes are suggested for executing various modules in the probabilistic security evaluation and economic evaluation. |
