Study and application of OLAP data warehouse in decision of power system dispatching

A real power system is selected as the research background. Based on analyzing and reorganizing the originally existing dada sources, the power system dispatch data warehouse is formed and snowflake mode cubes for multi-dimension data are established. By using OLAP and data mining technology, forecasting load, analyzing and inquiring data warehouse are realized from different point view and multi-layers.
