全球能源互联网, 2023 针对特高压直流闭锁等原因造成的受端电网频率严重跌落问题，提出一种储能紧急频率控制策略。首先，建立储能参与紧急频率控制的数学模型。其次，对于大功率缺额后发电机组惯性响应不足问题，提出了改进的频率变化率（rate of change of frequency，RoCoF）下垂控制策略以提高储能的惯量支撑，根据储能比例分配系数实时调节储能虚拟惯性及下垂控制出力；惯性响应阶段以RoCoF下垂控制为主、虚拟惯性控制为辅，抑制系统频率变化率；结合频率调节需求和储能系统出力特点提出不同区域的调频策略 ...

面向新能源大规模消纳的大容量储能多分区两阶段优化配置方法研究 [PDF]
全球能源互联网, 2021 目前国内外对适应新能源大规模并网消纳条件下的大容量储能在多分区的协同优化配置研究较少,多关注在电源侧和微网中储能的优化配置问题,储能在电网侧多分区的配置效率不高。为了提高大容量储能在多分区配置的合理性,提出了一种满足新能源消纳的大容量储能多分区协同两阶段优化配置方法。在系统内新能源装机容量一定的前提下,综合考虑电网调峰、系统备用容量充裕性和新能源利用率等因素,采用时序生产模拟方法和序贯子问题法,可以确定系统中不同分区储能配置的合理容量,实现了储能在适应大规模新能源并网消纳条件下容量合理配置的定量研究 ...

Retaining natural vegetation to safeguard biodiversity and humanity
Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Global efforts to deliver internationally agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services have been poorly integrated. These goals rely in part on preserving natural (e.g., native, largely unmodified) and seminatural (e.g., low intensity or sustainable human use) forests, woodlands, and ...

Conservation Biology, Volume 37, Issue 1, February 2023., 2023 Abstract Invasive species can dramatically alter ecosystems, but eradication is difficult, and suppression is expensive once they are established. Uncertainties in the potential for expansion and impacts by an invader can lead to delayed and inadequate suppression, allowing for establishment.

Global effects of forest modification on herpetofauna communities
Conservation Biology, Volume 37, Issue 1, February 2023., 2023 Abstract As the area covered by human‐modified environments grows, it is increasingly important to understand the responses of communities to the novel habitats created, especially for sensitive and threatened taxa. We aimed to improve understanding of the major evolutionary and ecological processes that shape the assemblage of amphibian and reptile ...

Methods in Ecology and Evolution, Volume 13, Issue 7, Page 1429-1435, July 2022., 2022 Abstract Over the past two decades, accelerometer (ACC) data have been increasingly used to study animal behaviours and energetics. However, the large amount of raw ACC data can be a burden to device storage and power consumption and in many cases may also require device retrieval for data collection.
