Abstract: |
The risk assessment was applied to analyzed the affect of transmitting power limit with the static load proportion parameter, based on the uncertain factor of load characteristic and parameter change. The Monte Carlo method may simulate the load characteristic change, and sample the static load proportion parameter at random, according to the load characteristic change. A set of risk index system, which described the influence of the load parameter change resulting in the transmitting limit, was put forward. The index system includes probability and loss risk of instability, probability and income risk of stability, total income risk. Then, the algorithm of risk assessment was studied based on stochastic load parameter. The transmission Cross-Section of one province power network was used as the example, and the risk index was received by simulation computing.
