摘要 | According to the insufficient of the wind power accommodation assessment, this paper proposed a new probabilistic assessment method. In the method, the randomness of the system load is considered. Firstly, the Gaussian mixture model of the power load is constructed. Secondly, the sample space of the load power is obtained by slice sampling from the probability model of load power. Finally, the sample values are substituted into the power flow equation to calculate the power flow and the value of the maximum wind power is determined under the condition of system safety operation constraints. The results of traditional research methods and the proposed method are compared in the reconstructive IEEE 39-bus system. When the sample size is 3000, the standard deviation of S-MCMC (Markov chain Monte Carlo with slice sampling) is only 0.08%, which shows that the proposed method has high accuracy and effectiveness. © 2019, Editorial Board of Acta Energiae Solaris Sinica.
