考虑时空互补特性的风光水火多能源基地联合优化调度

为促进风能、光能等新能源发电的消纳,实现风光水火多能源基地联合优化调度的调峰效益、经济效益以及环保效益的最大化,本文在分析风、光、水、火多能源介质时空特性的基础上,提出了一种以最小化火电机组运行成本、弃风量、弃光量、弃水量为优化目标的考虑风光水火时空互补特性的多能源基地联合优化调度模型,为特高压输电背景下送端多能源基地联合优化调度问题提供了一种参考方案。文中算例以时空差异特征显著的新疆地区和东部某区域的多能源基地为研究对象,通过实际算例的计算分析,验证了文中模型理论上能够促进新能源发电的消纳,降低火电机组的运行成本。

Combined Optimization Dispatching of Multi-source Hybrid Power BasesConsidering the Time-space Complementary Characteristics

In order to promote the power generation absorption of new energy like wind/light energy, and realize the maximization of pitch peak benefit, economic benefit and environmental protection benefit of combined optimization dispatching of multi-source hybrid power bases, based on the analysis of time-space characteristics of multi-source hybrid power, we put forward a combined optimization dispatching model of multi-source hybrid power that takes the minimum of operating cost, wind curtailment volume, light curtailment volume and water curtailment volume of thermal power unit as the optimization goal, and provide a reference method for the sending system combined optimization dispatching of multi-source hybrid power bases under the background of ultra-high voltage power transmission. The example takes multi-source hybrid power bases in the Xinjiang region and in the eastern part of a region as study abject, which have significant temporal and spatial differences. Through the calculation and analysis of practical examples, the model is verified theoretically can promote the absorption of new energy and reduce the operation cost of thermal power units.
