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 ...

Facilitating biodiversity conservation through partnerships to achieve transformative outcomes
Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Conservation biology is a mission‐driven discipline that must navigate a new relationship between conservation and science. Because conservation is a social and political as well as an ecological project, conservation biologists must practice interdisciplinarity and collaboration.

Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Conservation decisions are invariably made with incomplete data on species’ distributions, habitats, and threats, but frameworks for allocating conservation investments rarely account for missing data. We examined how explicit consideration of missing data can boost return on investment in ecosystem restoration, focusing on the challenge of ...

Balancing making a difference with making a living in the conservation sector
Conservation Biology, Volume 36, Issue 3, June 2022., 2022 Abstract Goals play important roles in people's lives because they focus attention, mobilize effort, and sustain motivation. Understanding conservationists’ satisfaction with goal progress may provide insights into real‐world environmental trends and flag risks to their well‐being and motivation.

Biodiversity Soup II: A bulk‐sample metabarcoding pipeline emphasizing error reduction
Methods in Ecology and Evolution, Volume 12, Issue 7, Page 1252-1264, July 2021., 2021 Abstract Despite widespread recognition of its great promise to aid decision‐making in environmental management, the applied use of metabarcoding requires improvements to reduce the multiple errors that arise during PCR amplification, sequencing and library generation.

全球能源互联网, 2021 并网型微电网的混合储能容量配置方法一般仅考虑其经济性，难以解决微电网联络线功率波动问题，会对电网产生不利影响。为了权衡混合储能的经济性与联络线功率波动平抑效果，提出了基于非合作博弈的混合储能容量优化配置方法。首先，以混合储能和联络线作为参与者，建立非合作博弈模型；其次，引入入侵杂草算法中繁殖机制和变异算子改进遗传算法，并求解模型；最后，对传统多目标优化模型、单目标优化模型和非合作博弈模型的优化结果以及传统、改进遗传算法的求解结果进行对比。结果表明：参与者进行博弈时可独立且客观优化目标函数 ...
