This invention discloses a method and system for configuring and restoring flexible resources and mobile energy storage in a power distribution network, belonging to the field of smart power distribution network technology. Based on a typhoon wind field and wind and rain load model, this invention constructs a time-varying failure rate for power lines and uses Latin hypercube sampling to generate a set of failure scenarios. Typical scenarios are obtained through scenario reduction. Based on the failure scenarios, in the pre-disaster stage, the invention identifies the deployment locations of smart soft switches (SOPs) and mobile energy storage systems (MESSs) that minimize the sum of pre-disaster investment costs and post-disaster recovery period weighted load shedding costs. In the post-disaster stage, time-varying accessibility constraints are constructed based on road travel time preprocessing results, establishing a collaborative recovery model that includes SOP operation, network reconfiguration, and MESS time-varying scheduling. This invention, based on the collaborative configuration and post-disaster control of flexible resources and mobile energy storage, effectively reduces the configuration cost of the power distribution network while improving its support and recovery capabilities in the face of extreme disasters such as typhoons.

This smart power supply tap comprises a power supply plug, a power supply jack, a relay switch, an electric leakage detection circuit, a communication unit, and a control unit. The power supply plug is configured to be connectable to an outlet to which AC power is supplied, and is supplied with AC power from the connected outlet. An electric device is connected to the power supply jack. The relay switch switches between conduction and interruption between the power supply plug and the power supply jack. The electric leakage detection circuit detects a leakage current value. The communication unit receives a switching signal for the relay switch from the outside. The control unit controls conduction and interruption by the relay switch on the basis of the detection result of electric leakage or the switching signal for the relay switch from the outside. At this time, when the leakage current value is equal to or greater than a first threshold value, the control unit controls the relay switch to perform interruption, and notifies the outside of the occurrence of electric leakage via the communication unit. When the leakage current value is less than the first threshold value, the control unit does not perform interruption and notifies the possibility of abnormality of the electric device via the communication unit.
