  This paper adopts a two-stage sample robust optimization (SRO) model to
address the wind power penetrated unit commitment optimal energy flow (UC-OEF)
problem for IEGSs. The two-stage SRO model can be approximately transformed
into a computationally efficient form. Specifically, we employ linear decision
rules to simplify the proposed UC-OEF model. Moreover, we further enhance the
tractability of the simplified model by exploring its structural features and,
accordingly, develop a solution method.
