Meshed Multi-Terminal Direct Current (MMTDC) Grid Protection and Control

近几十年来，全球对气候变化的关注与日俱增。为了实现能源部门的脱碳和更可持续的能源系统，应增加可再生资源在整个能源组合中的份额。风能是生产清洁能源的低成本替代能源之一，并提供了一种对冲更高的碳燃料成本的手段。最近，在风力发电项目上进行了大量投资。2014年，加拿大安大略省、魁北克省、艾伯塔省、新斯科舍省和爱德华王子岛共安装了37个风力发电项目，总装机容量为1871兆瓦。随着今年安大略省270兆瓦风力发电项目的安装，加拿大的风力发电装机容量最近已超过10千兆瓦。可再生资源的大规模整合，特别是风能，给电力系统的运行带来了各种挑战，并正在推动对改变现有输电基础设施的研究。

In recent decades, there has been a worldwide growing attention towards climate change. To move towards the decarbonisation of the energy sector and a more sustainable energy system, the share of renewable resources in the overall energy mix should be increased. Wind energy is one of the low-cost alternatives for generating clean energy and provides a hedge against higher carbon fuel costs. Recently, significant investments have been made in wind generation projects. In 2014, 37 wind power projects, totaling a production of 1871 MegaWatts (MWs), were installed in the Canadian provinces of Ontario, Quebec, Alberta, Nova Scotia and Prince Edward Island. With this year’s installation of the 270 MWs wind project in Ontario, Canada’s installed wind generation has recently surpassed 10 GigaWatts. The large integration of renewable resources, in particular wind energy, poses various challenges to the operation of the electrical power system, and is driving research into changing the existing transmission infrastructure.
