摘要: |
流域梯级水风光综合能源基地配建抽水蓄能构建水风光蓄互补系统,是提高风光消纳能力、加速可再生能源一体化开发的重要途径。水风光蓄互补系统因地制宜既可配置混合式抽水蓄能,又可配置传统常规抽水蓄能。针对何种配置方式更优问题,从调度运行需求出发进行了研究。首先量化分析了水风光资源的季节互补性和日内互补性。然后分别考虑配置混蓄与纯蓄,基于精细化流域梯级水电模型,以负荷跟踪偏差率最小、弃能最小、水量利用率最大为目标构建了水风光蓄互补系统短期优化调度模型,从调度运行角度探究不同抽蓄形式对水风光蓄互补系统的影响。最后,通过某流域梯级水风光一体化基地算例表明,配置混蓄相较于配置纯蓄,不同运行场景下负荷跟踪偏差率均更小、弃能均降低、水量利用率均提高,综合运行效率也得到提升,表明配置混蓄对水风光蓄互补系统调度运行的提升优于纯蓄。研究可为流域清洁能源基地、抽水蓄能规划建设及调度运行提供决策支持。 |

Abstract: |
The constructions of pumped-storage hydropower plants (PSHPs) and the hydro-wind-solar-storage (HWSS) complementary system within a cascade HWSS integrated energy base along the river basin are important means of improving the consumption of wind and solar power and accelerate the integrated development of renewable energy. The HWSS complementary system can be configured with hybrid or traditional pure PSHPs according to the local geographic conditions. To select the optimal configuration, this paper starts with the demands of the dispatching operation. First, the seasonal and intraday complementarities of hydro, wind, and solar (HWS) resources are quantitatively analyzed. Then, based on a refined cascade hydropower plant model along the basin and considering the respective configurations with hybrid and pure PSHPs, a short-term dispatching optimization model for an HWSS complementary systems is constructed with the minimum load tracking deviation rate, minimum energy curtailments, and maximum hydropower utilization rate as objectives. The impacts of different forms of PSHPs on the HWSS complementary system can thus be explored from the perspective of the dispatching operation. Finally, a case study on a cascade HWS integrated base along the basin shows that the configuration with mixed PSHPs exhibits smaller load tracking deviation rates, lower energy waste, and higher hydropower utilization rates, in different operating scenarios, than the configuration with pure PSHPs. The overall operating efficiency is also improved, which indicates a better improvement of the HWSS complementary system’s dispatching operation by the configuration with mixed PSHPs than that with pure PSHPs. This research can provide decision support for the planning and dispatching of clean energy bases and PSHPs along river basins. |
