The energy storage system (ESS) has advantages in smoothing the fluctuations, shifting peaks, filling valleys and improving power qualities. In particular, on distribution networks, ESS can effectively alleviate the spatial-temporal uncertainties brought by the extensive access of distributed generation (DG) and electric vehicles (EVs) [ 1, 2 ].
