Advanced grid development

风能和太阳能光伏发电是世界上增长最快的能源。这一趋势表明，在未来2-3年内，风电和太阳能光伏发电在电网中的渗透率将显著增长。从1996年到2014年，风电在公用电网中的渗透率几乎从6100兆瓦成倍增长到293,500兆瓦。光伏电池的价格在过去十年中急剧下降，并导致进一步利用太阳能光伏发电的重大技术和经济激励，并导致其在公用电网中的高度渗透。预计2017年全球光伏发电容量为322，000兆瓦。加拿大太阳能发电能力从2009年的约50兆瓦增加到2014年的（估计）2000兆瓦。此外，令行业观察人士惊讶的是，大型太阳能光伏发电厂，例如，290兆瓦和550兆瓦的发电厂在技术上和经济上也是可行的，并成功地融入了公用电网。

Wind energy and solar-PV energy are the world fastest-growing energy resources. This trend indicates that the level of penetration of the wind and solar-PV power in the electric power grid will significantly grow within the next 2-3 decades. From 1996 to 2014, the level of wind power penetration in the power utility grid has almost exponentially increased from 6100-MW to 293,500-MW. The price of PV-cells has dramatically dropped during the last decade and resulted in significant technical and economical incentives for further utilization of solar-PV power and resulted in its high depth of penetration in the utility grid. The estimated global PV-power capacity for 2017 is 322,000-MW. The Canadian solar electricity capacity has increased from about 50-MW in 2009 to (estimated) 2000-MW in 2014. Furthermore, to the surprise of the industry observers, large-size solar-PV power plants, e.g., 290-MW and 550-MW plants, also have become technically and economically viable and successfully integrated in the utility grid.
