Optimization on Power System Unit Commitment with Wind Power Based on Discrete Crisscross Algorithm
摘要
Abstract
Randomness and volatility of wind power brings serious challenges to safe and economic operation of the power system and reasonable wind power uncertainty model and unit commitment (UC)optimization method are critical to ensure safety and economy of day-ahead dispatching of the power system.Therefore,this paper presents a kind of UC optimization method for the power system with wind power based on discrete crisscross algorithm.According to day-ahead predictive val-ues and error distribution of wind power,this method adopts Latin hypercube sampling technique and Cholesky decomposi-tion to generate large numbers of wind power scenarios and uses synchronous back generation reduction method to reduce those wind power scenarios to small numbers of most likely scenarios.Aiming at minimizing the expected operational costs of thermal power generating units under the most likely scenarios,it establishes the UC optimization model,meanwhile it pro-poses the optimized method based on discrete crisscross algorithm to solve difficulties in UC optimization.Experimental sim-ulation verifies effectiveness of the proposed method.关键词
