Resilience enhancement of active distribution networks in the presence of wind turbines and energy storage systems by considering flexible loads

•Providing a stochastic MILP model for distribution system resilience enhancement.•Reducing the ENS by optimal placement of sectionalizing switches and backup DGs.•Reducing the ENS by applying DR program on normal and low priority loads.•Utilizing the maximum generation potential of DERs through topology change.•Improving voltage profile by placement of sectionalizing switches and backup DGs.•Considering different type of loads in the model.
