AI summary

A distributed energy system, an energy intelligent terminal, and a control method thereof are disclosed. It determines an error between the sum of initial random external input power that can be assumed by each of all the energy intelligent terminals and target power, updates the alternative operation mode for each energy intelligent terminal in an iterative manner when the error satisfies an iteration start condition until an iteration exit condition being satisfied, and determines the alternative operation mode for each energy intelligent terminal in the final iteration period as the operation mode for next duty cycle so as to regulate operation mode of the distributed energy system in real time according to the target power and energy consumption power of load to which each energy intelligent terminal corresponds. The distributed energy system has ad hoc network capability with the characteristics of fast deployment and plug and play terminals.
