水光互补技术研究及应用

Hydro-photovoltaic complementary technology research and application

青海省具有优良的太阳能资源和广阔的荒漠化土地资源,具备大规模开发太阳能光伏发电条件。为了实现青海地区光伏发电大规模开发与高原生态保护的共同推进,本文创新性地提出了"虚拟水电"的概念。将光伏电站作为水电站的额外机组,通过水轮发电机组的快速调节作用补偿光伏发电的出力波动,以达到优化光伏发电电能质量的目的。同时,开展了光伏电站对当地生态的影响研究,开展了经济作物种植试验研究,在光伏电站带动高原生态环境建设方面取得了一定成果。

Qinghai Province has excellent solar resources and vast resources of decertified land, providing an ideal condition for large-scale development of solar photovoltaic power. This paper describes a new concept, virtual hydropower, that was aimed at large-scale development of photovoltaic power in Qinghai and ecological protection of the plateau regions in China. In this concept, a photovoltaic power plant is used as an additional unit of a hydropower station that rapidly adjusts its generating units and compensates for fluctuations in the photovoltaic power output so as to achieve an optimized total power output. Besides, studies were carried out on the impact of photovoltaic power plants on the regional ecological systems and on the cultivation of economic crops. Thus, progress has been made in using photovoltaic power plants to improve the ecological environment in the plateau regions.
