Description

Technical field:

[0001] The invention belongs to the field of power demand analysis and prediction, and in particular relates to a multi-dimensional and multi-factor based power demand forecasting system framework. Background technique:

[0002] Power demand analysis and forecasting is an important daily work of dispatching operation departments and power service departments at all levels of the power system, and is the main basis for formulating power generation plans and transmission schemes. Improving the technical level of load analysis and forecasting is conducive to planning power consumption management, rationally arranging power grid operation mode and unit maintenance plan, helping to save coal, oil and power generation costs, formulate a reasonable power supply construction plan, and improve the economic benefits of the power system and social benefits.

[0003] However, based on economic transformation and key industry development, regional pattern and main funct...
