摘要: The invention discloses a probabilistic power flow determination method and system based on system. comprises the following steps of: acquiring data of plurality wind turbines; A Gaussian mixture model input variables is constructed according to all turbines. Genetic algorithm used solve parameters model. include weight coefficient each sub-component, mean value sub-component variance sub-component. MixtureModel with Input Variables Determined by Parameters; Obtaining linear equation tidal current equation; According equationmodel equation, joint probability density function output obtained determine can greatly reduce fitting error, has good effect fan, thereby improving analysis precision current, more accurate stability theline, whole process simple calculation speed fast.
