Abstract Private land protection is an important and growing tool to address biodiversity loss and climate change. Thus, better empirical evidence on the effectiveness of private land protection and organizational practices, such as targeting of lands for protection and choice of protection mechanism (i.e., fee simple land acquisition and conservation ...

随着风电、光伏的大规模并网,电力系统面临灵活调节能力不足的挑战。水电运行灵活,通过与风光协同规划、互补运行,能有效平抑新能源出力波动,保障并网消纳。水风光协同规划的关键之一在于对水电灵活调节能力进行准确建模,其中振动区约束不容忽略。为此,提出了考虑水电振动区的水风光协同规划模型。该模型首先利用组合数学技术将水电机组振动区合成为电站振动区;然后,综合考虑振动区约束及梯级水力联系、水力发电方程等各项约束,实现对水电系统的准确建模;最后,耦合水电系统与新能源、联络线等相关运行约束形成水风光协同规划模型 ...
