Two-stage stochastic robust optimal scheduling of virtual power plants
considering source load uncertainty
Abstract
Aiming at the optimal scheduling problem of virtual power plant ( VPP )
with multiple uncertainties on the source-load side, this paper proposes
a two-stage stochastic robust optimal scheduling method considering the
uncertainty of the source-load side. This method combines the
characteristics of robust optimization and stochastic optimization to
model the source-load uncertainty differentiation. The Wasserstein
generative adversarial network with gradient penalty ( WGAN-GP ) is used
to generate electric and thermal load scenarios, and then K-medoids
clustering is used to obtain several typical scenarios. The min-max-min
two-stage stochastic robust optimization model is constructed, and the
column constraint generation ( C & CG ) algorithm and dual theory are
used to solve the problem, and the scheduling scheme with the lowest
operating cost in the worst scenario is obtained.
