The application discloses a kind of active
distribution system non-
simulation reliability evaluation methods considering flexible
interconnection, comprising:1 constructs the active
distribution system topological model including main power supply,
backup power supply, feeder
branch, sectionalizing switch, tie switch, flexible
interconnection equipment and load node;2 in single-line fault
scenario, three-way topological search is carried out along main power supply path,
backup power supply path and flexible
interconnection support path respectively, and recoverable power supply node set is obtained and
recovery domain division is completed;3 establish the non-
simulation calculation model of load node repair outage and switch switching outage;4 the variation of load node outage time before and after flexible interconnection access is unknown, and the equivalent linear equation set is established, and the
node level and
system level reliability index is solved.The application can depict the fault
recovery relationship when flexible interconnection equipment participates in multi-path collaborative
recovery, so as to improve the efficiency and accuracy of active
distribution system reliability evaluation.
