With the continuous development of distributed energy, the distribution grid's demands for flexibility and operation efficiency are improved rapidly. However, massive devices connected to the distribution grid make the service data of the distribution grid grow explosively and bring difficulties to the processing and decision-making. This paper constructs a digital twin-enabled computation offloading architecture of distribution gird and proposes a service priority-driven digital twin-enabled autonomous decision-making algorithm based on price matching to realize autonomous decision-making of computation offloading. It can address the conflicts among devices and achieve service priority awareness by increasing the matching cost of servers based on the service priority. Simulation results show that the proposed algorithm has the superior performance in delay and service satisfaction rate.
