英文摘要：

The load forecasting is an important task of power utilities, which is wildly used in the dispatching and operation planning of power systems, and the accurate load forecasting is helpful for the security and stability of power systems as well as reducing the power generation costs. With the estabhshment and development of the power market, load forecasting will play a more important role in power systems. The definition and meaning of load forecasting were introduced. The current load forecasting methods were classified and the basic theories, advantages and disadvantages of different methods were described. Finally, the future development direction of the load forecasting methods was discussed.
