A Dynamic Probabilistic Load Flow Method Considering Random Distribution of the Unbalance Power
Probabilistic load flow (PLF) is a basic tool for uncertain study. To improve the fitting degree between analysis results and actual situation, a dynamic probabilistic load flow (DPLF) method considering distribution of the random unbalance power is proposed in this paper. Based on the probabilistic characteristic analysis for dynamic random variables, bus injection uncertainties caused by random wind power and loads can be represented as their moments and cumulants. Then the distribution model of unbalance power considering random factors is established and the calculation method of bus distribution participation factors is discussed. Results of a real power system in China with 151 buses and 252 branches are analyzed and compared to those obtained by Monte Carlo simulation. A numerical test shows that the effectiveness of the proposed method.
