Abstract: After extreme events and major outages in the distribution system (DS), restoring the de-energized loads becomes the priority of network operators. In such conditions, static energy storage systems (SESSs) and mobile energy storage systems (MESSs) are critical resources for DS outage management to fast restoration of the network. Finding the de-energized islands and associated loads, investigate the optimal load pickup sequence along optimal dispatch of energy storage systems (ESSs) are the main challenges of network outage management in outage duration. Motivated by these challenges, this paper presents a new load restoration strategy by black start distributed generators and non-black start distributed generators and enhances black start service considering static/mobile energy storage systems, and interdependency between transportation and power grids. To this end, a new method is presented, which indicates the formed de-energized islands and their loads after fault occurrence in the network. This method also can check the radiality constraint of the network. In addition, in this paper, a new algorithm is presented that evaluated the best load pickup sequence by considering the priorities of the loads. Various case studies and scenarios are carried out in an IEEE 123-bus distribution system considering the different numbers of faulted lines, damaged roads MESSs and SESSs. Simulation results confirm the efficiency of the proposed restoration strategy.
