The invention relates to the technical field of
power load regulation and control, in particular to an
electric vehicle charging and discharging load aggregation
potential assessment method,
system and device and a medium, and the method comprises the steps: obtaining a
traffic network topology and a power distribution
network topology, considering a travel demand in the
traffic network topology, considering charging and discharging
load distribution in the power distribution
network topology, and calculating the aggregation potential of the charging and discharging load; identifying space-
time distribution of charging and discharging loads of the
electric vehicle; based on the time-space distribution of the charging and discharging load and the time-domain fluctuation of the
bus load in the power distribution
network topology, evaluating the influence of the
bus load fluctuation on the
power flow distribution; the method comprises the following steps: constructing an
electric vehicle response quantity model based on time-space distribution of
charge and discharge loads, obtaining an electric vehicle intraday response capability condition based on
fuzzy reasoning, and evaluating the electric vehicle aggregation response potential based on an
evaluation result of influence of
bus load fluctuation on
power flow distribution and the electric vehicle intraday response capability condition. The problem of insufficient regulation potential mining caused by insufficient consideration of the global influence of the local charging and discharging behavior in the existing evaluation technology is effectively solved.
