The requirements made on the dispatch scheduling system by the current rapid development of ultra-high voltage (UHV) power grids in China are elaborated. By referring to the actual demand for the UHV power grid integrated dispatch scheduling in future and the status quo of the dispatch scheduling available

a service-oriented architecture (SOA) based auxiliary decision-making system of integrated dispatch scheduling is proposed

and an integrated dispatch scheduling auxiliary decision-making service set is designed. The corresponding key technologies are researched

and the prospects for the integrated auxiliary decision-making system proposed.
