Abstract: Disclosed is a power grid transmission and distribution cooperative dispatching method and system in a power market environment, relating to the technical filed of power market. The method includes: power grid transmission and distribution data are collected, and economic dispatching modeling is carried out on a hybrid system containing hydro-thermal power; linearization processing is carried out on nonlinear terms in the model; and accelerated solving is carried out on the model by adopting Benders decomposition, so that power gird transmission and distribution cooperative dispatching is optimized. The integration capacity of the power system containing hydro-thermal power to the renewable energy is enhanced, and the utilization efficiency of resources is improved, and the solving process is simplified in the present invention.

Abstract: The invention discloses a method for managing communication authority based on multi-energy equipment data flow using digital twin and a system thereof, comprising the following steps: generating a unique permission code; Establishing a data flow interaction channel; utilizing a broadcast detection mechanism to periodically check the data flow communication authority based on the channel and continuously remove the data flow interaction channel that is expired and illegally authorized, thus to complete the data flow communication management. The present invention has the advantages that the management is more scientific, the algorithm is clearer, more efficient and safer, and the level is well arranged; the channel resource utilization rate is improved, filling the gap in the current stage of a method for managing communication authority based on multi-energy equipment data flow using digital twin and a system thereof, and ensuring the real-time mapping between physical entities and virtual images.
