The access of high proportion of fluctuating power sources increases the power fluctuation of the contact line between the microgrid and the upper-level power grid.It challenges the safe and stable operation of energy system.Aiming at the problem of insufficient adjustable capacity of energy microgrid

an electric hydrogen energy microgrid architecture incorporating cluster electric vehicles is proposed. First

following the idea of "unified quantification of feasible domains"-"efficient aggregation of feasible domains" for resources

the adjustable capability of differentiated electric vehicles is quantified in a unified manner based on the virtual battery model.The power feasible domain of clustered electric vehicles is aggregated using the relaxed Minkowski summation method. Second

considering the uncertainty in photovoltaic output fluctuations

a stochastic optimization model for power suppression in the microgrid is established based on DTW-K-means scenario reduction.Finally

simulation results show that the proposed model has a positive effect in promoting the suppression of power fluctuations in the energy microgrid.
