摘要

提出风光新能源接入大水电基地下梯级水电站群中长期调度方法。基于优化的典型输电功率曲线,以水库日平均实际下泄流量为边界,开展水风光互补小时尺度的长系列运行调度模拟,进而提取新能源弃电率与水电出力的响应函数,再将其嵌入水风光互补中长期调度模型中,采用模拟-优化方法推求适应性调度规则。以某清洁能源基地为实例,结果表明：随着水电出力的增加,弃电率先下降后抬升,水电出力在适中范围内可使得风光弃电率较小;相比于常规调度,单纯优化水电运行方式可降低风光弃电率3.71%,系统总发电量提升1.74%;嵌套响应函数的互补运行优化使得风光弃电率下降7.68%,系统总发电量提高2.15%。因此,所提方法可进一步挖掘水电灵活性,协调水电与新能源的互补关系,进而提升水风光互补系统整体互补效能。

Abstract

This paper proposes a medium- and long-term scheduling method for wind and solar power integration into cascaded hydropower stations. Based on optimized typical transmission power curves, with the daily average actual discharge flow of reservoirs as a boundary condition, a long-term hourly-scale simulation of hydro-wind-solar complementary operation is conducted. Subsequently, the response function between renewable energy curtailment rate and hydropower output is extracted and embedded into the medium- and long-term hydro-wind-solar complementary operation model. A simulation-optimization method is adopted to derive adaptive operating rules. A case study on a clean energy base demonstrates： As hydropower output increases, the curtailment rate first decreases and then rises, with moderate hydropower output leading to lower wind and solar curtailment rates. Compared with conventional scheduling, optimizing hydropower operation alone reduces wind and solar curtailment rate by 3.71% and increases total system generation by 1.74%. The complementary operation optimization incorporating the response function further reduces wind and solar curtailment rate by 7.68% and enhances total system generation by 2.15%. Therefore, the proposed method can further exploit hydropower flexibility, coordinate the complementary relationship between hydropower and new energy, and improve the overall complementary efficiency of hydro-wind-solar integrated systems.
