Abstract: |
As the power control technology of wind farms
develops, the output power of wind farms can be constant,
which makes it possible for wind farms to participate in
power system restoration. However, due to the uncertainty
of wind energy, the actual output power can’t reach a
constant dispatch power in all time intervals, resulting in
uncertain power sags which may induce the frequency of
the system being restored to go outside the security limits.
Therefore, it is necessary to optimize the dispatch of wind
farms participating in power system restoration. Considering
that the probability distribution function (PDF) of
transient power sags is hard to obtain, a robust optimization
model is proposed in this paper, which can maximize the
output power of wind farms participating in power system
restoration. Simulation results demonstrate that the security
constraints of the restored system can be kept within
security limits when wind farm dispatch is optimized by
the proposed method. |
