Self-Adaptiveive Step Size Adjustment Method of Digital-Analog Hybrid Simulation towards Urban Energy Internet

The digital-analog hybrid simulation for urban energy internet is an significant technical method to verify the optimization strategy of urban energy internet operation. A comprehensive optimization objective design method is put forward in this paper. The method is used for the simulation step size of urban energy internet in the mixed simulation of digital and analog. Also an adaptive mechanism for the simulation step size according to an adapted filtering ideal transformer interface model is designed. The degree of effectiveness and degree of accuracy of the proposed method were verified through numerical examples.
