| Abstract: | Based on the rough set theory forecast and artificial neural network,a new method of load forecasting is put forward.The rough set is used to analyze the condition attributes reduction based on uncertain and incomplete original data.These attributes are then applied to the artificial neural network as the input vectors to forecast load.The improved genetic algorithm is used to amend neural network weights.The calculation examples show that the presented method is feasible and effective. |
