The invention discloses an interval-taylor-model-based system and method for forecasting a short-term load of a power system, and can be used for analyzing the influence of the basic data uncertainty to a forecasting result and saving the computing time greatly. The system comprises a data acquisition module used for leading data into a database module, a data preprocessing module used for describing the uncertainty of basic data via using an interval arithmetic so as to sectioning all the basic data and transmitting the result into the database module, a load forecasting and analyzing module used for forecasting the short-term load via using an interval taylor formula model short-term load forecasting formula, a result management module used for converting and outputting the result and transmitting the analysis result into the database module, and the database module used for storing the data generated by the data acquisition module, the data preprocessing module, the load forecasting and analyzing module an
