An Alternating Direction Method of Multipliers for Unit Commitment Optimization Based on Wind power Accommodation

With the increasing proportion of wind power access, the traditional model of unit commitment cannot meet the current development needs. In this paper, in order to better balance the cost and wind power economy, a comprehensive model considering operation cost and wind power accommodation is proposed to evaluate unit commitment problems. Based on the evaluation functions, the optimization of unit commitment problems is transformed into multi-objective constraints problem, the proposed algorithm by combining alternating direction method of multipliers and nonlinear fraction programming is proposed to solve the problem. The model and algorithms are applied to estimate a 10 unit system. It is show that the system needs to balance the cost and wind power economy, and the proposed modeling method can bring good results for unit commitment problems.
