The invention belongs to low-voltage network load prediction technical field, a kind of low pressure grid based on KNN and roulette algorithm is provided to become more meticulous load forecasting method, this method combines KNN algorithms and carries out classification work according to development degree to all grids first, then the large user in region is found out to stop over grid, calculate the probability that all types of grids are increased with friction speed, its load growth is finally calculated using roulette algorithm, and its interior index is updated every year to complete the renewal of its development degree, so as to complete the stochastic and dynamic prediction of load.Forecasting Methodology of the present invention is effectively using the non electrical quantity information of urban planning and plot property etc. and low-voltage customer load strong correlation come auxiliary power prediction work, while taking into account the load development randomness of actual grid, load prediction is relatively reliable efficiently. |
