中国和加拿大如何应对限风问题——来自加州的教训

How Could China and Canada Handle Their Wind Curtailment Issues——Take California as an Example

2015年《巴黎气候协定》达成后,全球风电发展规模的持续增长将继续改变许多司法管辖区的能源供应结构。几十年前,大多数地区的供应组合以水电、煤炭和天然气为主。再生能源是能源组合中的一小部分,因此至关重要。然而,可变可再生能源的高普及率也带来了一些挑战。限风限电是一种维护系统平衡的可靠性方式,但同时,过度限电也会使脱碳目标和投资者对可再生能源的信心产生负面影响。本文通过比较中国、加拿大(阿尔伯塔省)和美国(加州)在处理弃风问题上的法律政策,提出了完善中国和阿尔伯塔省法律制度的建议。

The sustained growth in the scale of global wind power following the 2015 Paris Climate Agreement has and will continue to change the energy supply mix in many jurisdictions.A few decades ago,the supply mixes in most jurisdictions were dominated by hydro,coal and natural gas.Variable renewable sources of energy,once a small part of the energy mix,are now becoming critical.However,the higher penetration of variable renewable energy also presents several challenges,such as wind curtailment.Curtailment serves as a means to maintain system balance and reliability;simultaneously,excessive curtailment negatively affects the decarbonization targets and investor confidence in renewable power.By comparing the legal policies of China,Canada(Alberta Province)and USA(California)in dealing with wind curtailment,this paper puts forward some suggestions for the improvement of the legal system of China and Alberta.
