To support the flexible aggregations of multiple resources

such as the distributed power

controllable load and energy storage under the novel power system

to implement the interaction between power grid and the aggregations

a virtual power plant system which can support dynamic aggregation of equipment is designed and implemented. The proposed virtual equipment packaging technology can eliminate the differences between equipment

and establish virtual units in a unified measurement standard. The equipment-level power generation forecasting and multi-load forecasting engines ensure the prediction accuracy and the flexibility of aggregations. The solution of the cloud-edge collaboration achieves the vertical aggregation of resources. Through deployment verification

the system can dynamically aggregate multiple types of resources to participate in grid interaction

and effectively improve the accuracy of new energy generation power prediction and load prediction

achieving flexible resource efficiency

precision

and flexible regulation，further ensuring the safe and stable operation of the power grid.
