发电侧电力市场下的梯级水电厂日优化运行研究

Study on optimal daily operation of cascade hydropower plants under the generation side power market

本文对边际电价的预测方法进行分析,并立足于电力市场现状,从目标函数、约束条件、算法等方面着手,构建梯级水电厂日优化模型,最后通过案例分析的方式,以某梯级发电厂为例,对边际电价与日运行优化结果进行分析,结果表明,时间序列思想与边际电价变化规律相符合,总体预测准确性较高,该方法科学可行。

This paper analyzes the forecast method of marginal electricity price, and based on the current situation of power market, constructs the daily optimization model of cascade hydropower plant from the aspects of objective function, constraint condition, algorithm and so on. Finally, taking a cascade power plant as an example, the results of marginal electricity price and daily operation optimization are analyzed.
