太阳能发电技术的应用与发展

随着全球能源需求的不断增长,能源、环境和气候变暖等问题日益突出。倡导低碳经济运行,提高资源利用率,加大利用可再生能源力度,进一步减少化石能源消耗,保护生态环境,共同推进人类社会和谐可持续发展,已成为全社会的共识和责任。文章介绍了太阳能光发电与太阳能热发电的基本方式和发电技术,阐述了随着能源市场份额的不断增长,需要重点关注和解决独立运行与并网运行的安全、可靠及系统兼容问题,并指出将太阳能发电与智能电网、大容量热储存系统进行整合,是今后太阳能发电的方向。

通往100%可再生能源之路

构网型逆变器可以满足我们对电网的需求。由考艾岛公用事业合作社运营的卡帕亚太阳能+储能设施(前页图)存储了52兆瓦时的能量,采用的是特斯拉的Powerpack2电池系统。在理想条件下,该设施的光伏板(本页上图)的发电功率为13兆瓦。另一座太阳能+储能设施位于考艾岛西南部的美国海军太平洋导弹靶场(本页下图)。

Integrating high levels of variable renewable energy into electric power systems

As more variable renewable energy(VRE)such as wind and solar are integrated into electric power systems,technical challenges arise from the need to maintain the balance between load and generation at all timescales.This paper examines the challenges with integrating ultrahigh levels of VRE into electric power system,reviews a range of solutions to these challenges,and provides a description of several examples of ultra-high VRE systems that are in operation today.

Guest Editorial:Special Section on Integrating Ultra-High Levels of Variable Renewable Energy

Wind and solar energy have seen significant decreases in the cost of these technologies over that last decade which has lead to increasing levels integrated into the grid.They also offer unique benefits such as no fuel costs,quick installation,and no pollution.But as more variable renewable energy(VRE)such as wind and solar is integrated into electrical power systems.
