  Increasing penetration of wind and renewable generation poses significant
challenges to the power system operations and reliability. This paper considers
the real-time optimal transmission switching (OTS) problem for determining the
generation dispatch and network topology that can account for uncertain energy
resources. To efficiently solve the resultant two-stage stochastic program, we
propose a tractable linear decision rule (LDR) based approximation solution
that can eliminate the uncertainty variables and lead to fixed number of
constraints. The proposed LDR approach can guarantee feasibility, and
significantly reduces the computational complexity of existing approaches that
grows with the number of randomly generated samples of uncertainty. Numerical
studies on IEEE test cases demonstrate the high approximation accuracy of the
proposed LDR solution and its computational efficiency for real-time OTS
implementations.
