Under the background of establishing a new power system with new energy as the main body, and in order to meet the development needs of new power system, a construction scheme of main distribution integrated dispatching and control system is proposed. By establishing a dispatching and control platform suitable for the participation of distributed generation and controllable load in a wide area, the method of combining cloud control and local control is adopted. The monitoring and control functions of the main power grid and distribution network are organically combined, which will effectively improve the coordination ability of source-grid-load-storage and the consumption level of clean energy.
