Probabilistic Load Flow Calculation Method Based on Multiple Integral Method Considering Correlation of Photovoltaic Generation
摘要
Abstract
Due to the impact of the correlation and uncertainty of photovoltaic (PV) generation on power system, it is necessary to apply probabilistic load flow (PLF) considering correlation of PV generation to obtain the statistics of system characteristic quantities. A modified Nataf transformation was proposed to handle the correlation of PV generation in this paper. Based on the traditional Nataf transformation, a third-order polynomial normal transformation was adopted to reduce computational effort of traditional Nataf transformation. In order to simplify the computational complexity induced by the nonlinear relationship between input and output variables of PLF, multiple integral method (MIM) and Gram-Charlier expansion were introduced. Based on load flow calculation corresponding to specified input variables, high precision results of output statistics can be estimated. An IEEE 39-bus system was tested in the simulation study. The simulation results verified the effectiveness, accuracy and efficiency of the proposed algorithm. Comparison between cumulant method and MIM confirmed the limitation of cumulant method and well performance of MIM.关键词
