Abstract:In view of the problems that extreme disasters can cause distribution network lines to be disconnected and loads to lose power，a two-stage distribution network resilience improvement strategy considering mobile energy storage and soft open point as flexible resources is proposed. First，a two-stage pre-disaster robust optimization model is built under the power distribution-traffic coupling network，and pre-disaster deployment of mobile energy storage under the worst photovoltaic output scenario is carried out，and the location and quantity deployment plan of mobile energy storage is obtained. Then，based on the pre-disaster deployment plan，a multisource coordinated post-disaster fault recovery hybrid second-order cone programming model is established，and then the optimal dispatch of soft open point，mobile energy storage，and electric vehicle charging and discharging are taken into consideration to obtain the optimal post-disaster fault recovery. The scheme and numerical example analysis verify the effectiveness of this strategy.
