Accessing power grid of intermittent distributed energy and controllable elements such as energy storage devices and flexible loads have increased the complexity of optimal dispatch of active distribution network. Proposed here is the architecture and application of multi-source coordinated optimal dispatch

plus researches on a series of key technologies

including multi-source information blend

fast simulation

optimal dispatch strategy and its implementation and evaluation. Also

the “3D” optimization objective in sequential

spatial and operational scales is designed

alongside spatial-scale optimal strategy of distribution network-feeder-autonomous region and sequential-scale optimal strategy of long time-short time-real time

as well as the assessment method of optimal strategy. Finally

the application scenarios of multi-source coordinated optimal dispatch for the active distribution network are devised.
