Generalized Sigma approach to unit commitment with uncertain wind power generation
Extended the 3? unit commitment to study wind integration in congested power grids. Treated bus residual demands and line power flows as correlated random variables. Used a few representative scenarios to contain uncertainty with certain probability. Offering strikingly lower computational burden with reasonable accuracy. Measured computational performance using two comprehensive case studies.
