The contrariety of the computational effort and accuracy is solved well. (4) The results of the IEEE RTS 24-bus test system show that the proposed method is efficient in system evaluation.

• （4）IEEE-RTS 24节点算例结果验证了本文所提出的MCMC方法应用在电力系统可靠性评估中的正确性，相比于传统的蒙特卡洛方法，MCMC方法可以显著提高计算指标的收敛速度，节省计算时间，提高计算的稳定性，并显示出在大型电力系统可靠性评估中具有很大的优越性。
