The invention discloses a chicken
flock optimization-based power distribution network
distributed power supply adaptive protection coordination method,
system and device, and a storage medium, and relates to the technical field of power
system relay protection, and the method comprises the steps: collecting
power grid operation data in real time through intelligent
electronic equipment of each node, and judging whether the
system state is changed or not; if the state is changed or a fault trigger
signal is received, carrying out
power flow and
short circuit calculation to obtain a newest fault current; evaluating action coordination of the main
relay and the
backup relay, and determining whether to start parameter optimization or not according to a result; if starting, constructing a model, solving by using a chicken
flock algorithm, and finally issuing optimization parameters to update a relay protection constant value; according to the invention, online adaptive setting of power distribution network protection is realized, the fault isolation precision and the
system stability are improved, and the risk of protection maloperation is reduced.
