Load Shedding Method of Power Restoration of Distribution Network Based on SOP

Soft Open Point (SOP), which can accurately control the power flow on both sides and increase grid flexibility, is a power electronic device replacing the traditional tie switch. This paper considers the application of SOP and the impact of different load shedding scheme on power restoration in distribution network. A mixed integer second-order cone programming (MISOCP) is used to solve the problem. Finally, the test is implemented in the IEEE 33-bus system. The result demonstrates that SOP is conducive to the power restoration of distribution network. And completely load shedding is better than part of load shedding without considering the criticality of the load.
