论文摘要
一些美国各州已经设定了清洁能源目标和目标，以使其电力部门脱碳。此类目标和目标的原因有很多，包括气候变化的越来越明显的影响。少数州（华盛顿，加利福尼亚州，纽约和弗吉尼亚州）的目标是到2050年或更早之前进行深度脱碳化，从今天起只有30年或更短的时间。避免灾难性气候影响所需的大量碳排放量（到2030年到2030年）的紧迫性需要比某些最初的目标（例如，在现在到2030年之间的30％可再生投资组合标准）更具雄心勃勃的努力（例如30％可再生投资组合标准），而最近几年的投资均比预期的是，经济能源更加清晰，很快就会投资。考虑到这一点，本报告研究了区域间交流和高压DC（HVDC）传输升级的组合，并增加了评估大规模传输扩展的好处。
Some U.S. states have set clean energy goals and targets in an effort to decarbonize their electricity sectors. There are many reasons for such goals and targets, including the increasingly apparent effects of climate change. A handful of states (Washington, California, New York, and Virginia) are aiming for deep decarbonization by 2050 or earlier, a mere 30 years or less from today. The urgency of substantial carbon emissions reduction (50% or more by 2030) needed to avoid catastrophic climate impacts requires even more ambitious efforts than some of the original targets (e.g., a 30% renewable portfolio standard) set for between now and 2030. With the cost of solar and wind energy falling faster than expected in recent years, economics are also driving rapid expansion of clean energy investments. With this in mind, this report examines combinations of interregional AC and High-Voltage DC (HVDC) transmission upgrades and additions to evaluate the benefits of large-scale transmission expansion.
