【Abstract】 Based on the analysis of the new requirements involved in Bus load forecasting under Energy-Conservation Based Generation Dispatching, the platform of bus load forecasting was proposed and designed. B/S structure mode and J2EE technology architecture as well as high-performance network database were applied in this platform. Focusing on bus load analysis and forecasting, some practical functions including module of data acquisition, data management, post-forecasting evaluation and report-checking management were integrated in this platform. Proposing key technologies such as bus load modeling, the pool of forecasting models, adaptive training mechanism and forecasting process control, the system was applicable for the new requirements. This is a flexible networked software platform for intensive data analysis, accurate demand forecast and integrative forecasting management. It can serve as an effective supporting tool for improving bus load forecast accuracy, ensuring secure and economical operation of power system.更多还原
