Abstract: load forecasting is an important foundation work of the control of power grid and power system planning. The load forecasting system researched in this paper adapted 3 layer construction which based on VB, .NET, and it established an forecasting platform which integrates province with town. It has 3 major functions: analysis of the feature of load, load forecasting and examination management, and this load forecasting system also has the functions of various kinds of load forecasting including: ultra short-term, short-term, extended
short-term, medium-term and long-term load forecasting. It took the meteorological factor and specific circumstance of the region into consideration, which embodies the intelligence of self-organization, self-learning and self-adapting. Now this system has been put into service in Hunan power grid, the practical application indicates that: this system can reduce the pressure of load forecasting and promote the precision of the forecasting, and it has a wonderful vista of popularization and application.
