Source-network-load-storage provincial-regional coordinated regulation and control method and system for new energy consumption

The invention discloses a new energy consumption-oriented source network load storage province and region coordinated regulation and control method and system. The method comprises the steps of calculating a power generation plan of each unit and a plan value of power transmission between a province and a region; the deviation power of the regional power grid is calculated through the actual wind power and photovoltaic power generation capacity of the regional power grid, the planned value of power transmission between provinces and regions before is corrected, and power balance of the regional power grid is achieved through energy storage and multi-element flexible resources of provincial dispatching and region dispatching; the provincial dispatching is used as an upper decision maker, and according to a pre-established provincial dispatching constraint condition, the power grid fluctuation is inhibited by cooperating with the local dispatching under the condition that the power deviation occurs in the local
