Aiming at the problems of large scale; complex constraints and difficult solution for day-ahead security-constrained unit commitment (SCUC) in the wind power interconnection grids; the proposed decentralized coordination optimization strategy based on target cascade analysis technology is proposed. The problem is decomposed into the upper optimization problem which is responsible for the coordination of voltage phase angle between the boundary nodes; and the lower optimization optimization the regional power generation schemes in parallel. The system operation uncertainties such as wind power; load forecasting error and forced shutdown of conventional units are quantified in each region with the expected wind power curtailed (EWPC) and the expected energy not supplied (EENS); which are introduced into the target function as punishment to comprehensively optimize the system reliability and economy. The effectiveness of the proposed model and algorithm is verified by two simulation examples of the 2-area with 12-node system and the IEEE RTS96 three-region interconnection system. © 2020; Editorial Board of Acta Energiae Solaris Sinica.
