TY - JOUR A1 - Schultz, RĂ¼diger A1 - Wollenberg, Tobias T1 - Unit commitment under uncertainty in AC transmission systems via risk averse semidefinite stochastic programs JF - RAIRO-Operations Research N2 - This paper addresses unit commitment under uncertainty of load and power infeed from renewables in alternating current (AC) power systems. Beside traditional unit-commitment constraints, the physics of power flow are included. To gain globally optimal solutions a recent semidefinite programming approach is used, which leads us to risk averse two-stage stochastic mixed integer semidefinite programs for which a decomposition algorithm is presented.
