竞争机制下基于改进遗传算法的火电机组启停

A modified genetic algorithm solution to confirm thermal unit commitment operation under competitive mechanism

电力市场正逐步引入厂网分开竞价上网的竞争机制,而发电厂的发电情况与电网的经济运行有极大的关系。在这种运行模式下,火电机组的优化启停数学模型需要进一步改进。本文从发电厂利润最大化角度出发,建立火电机组启停的数学模型,并提出用优化遗传算法确定火电机组启停的方法。该方法能有效克服一般遗传算法在机组优化组合中的不足,提高了收敛速度,对发电机组优化组合问题具有实用价值。

The competitive mechanism of the separation of net and factory begins coming into our country' s electricity market. Based on this mode the mode of thermal Unit commitment operation needs updating. In view of this the article brings up a solution method based on modified genetic algorithm. This method can overcome effectively the shortcomings of general genetic algorithm and enhance convergence speed.
