区域风能规划中的风资源参数及等效风速序列求解方法

Wind Resource Parameters and Equivalent Wind Speed Sequence Solution in Regional Wind Energy Planning

在面积较广阔、建有多个风速观测站的区域风能规划中,缺乏能够描述区域等效风资源状况的风速数据以及相应的求解方法。针对区域等效风速序列及风速分布特性参数难于求解的问题,调查总结了常用风能规划模型中用于描述风速变化特性及风资源分布的重要参数,分析了参数选择对风能规划的影响,提出基于多维自回归模型的区域等效参数及区域等效风速序列求解方法,给出一种仅利用月平均风速合成风速数据的方法。以可再生电力混合优化模型为计算平台,以建有多个风速观测站的某区域为算例,参数求解方法及合成风速方法的合理性进行了验证分析。结果表明,2种方法都能够求得合理的区域等效风速数据;利用月平均风速合成风速数据的方法,能够合成具有一定可参考性的、适用于区域风能规划的风速数据。

In regional wind energy planning multiple wind speed observing stations, it is absent of that wind speed data and its solving approach, which can describe regional equivalent wind resource condition well It is important but is difficult to solve regional equivalent wind speed sequence and wind speed distribution characteristic parameters. For this, it was summarized that important wind resource parameters, which describe wind speed distribution and wind resource situation, in commonly used wind energy planning models. Then, the impact of these parameters on energy planning was analyzed. Solution approaches for these parameters were proposed based on multidimensional regression model. Besides, an approach synthesizing wind speed sequence was presented, using only the monthly average wind speed on the platform of Hybrid Optimization Model for Electric Renewables （HOMER）. Validating analysis was carried out on a region owning several wind observation stations. The results show that the proposed methods achieve reasonable wind speed data; and the synthesizing wind speed method can gain wind speed sequence referenced and is applied to energy planning to some extent.
