光照水电站光伏电源接入改造设计研究

Design and Research on the Integration of Photovoltaic Power Supply in Illuminated Hydropower Stations

光伏发电出力昼夜变幅大,为提高电能质量,减少光伏发电直接上网对电网系统的影响,文章从工程设计角度,介绍了对现有水电站进行改造方案,将光伏等新能源电源接入改造后的水电站,利用水电站原有送出通道接入电网,通过水电站良好的调节性能,实现了水光互补、优化利用的水电发展模式。

The output of photovoltaic power generation varies significantly between day and night.In order to improve the quality of electric energy and reduce the impact of direct grid connection of photovoltaic power generation on the power grid system,this paper introduces the retrofitting scheme of existed hydropower stations from an engineering design perspective.It involves integrating new energy sources,such as photovoltaic power,into the modified hydropower stations.By utilizing the existed transmission channels of the hydropower station to connect to the grid,and leveraging the excellent regulation performance of the hydropower station,the water and solar power complement each other,achieving an optimized and efficient hydropower development mode.
