全球能源互联网, 2020 火电灵活性改造，特别是降低机组最小稳定功率，可有效增强系统调峰能力，缓解弃风弃光问题。但灵活调节需求随风光电源、负荷和电网运行特性动态变化而难以准确估计，火电厂易陷入过度投资或无序竞争的两难抉择而延迟乃至放弃改造，导致实际改造容量远低于国家规划预期。因此，如何在保证可再生能源消纳目标前提下科学规划火电机组的灵活性改造容量成为地区能源管理部门和火电厂共同关注的问题。首先建立了包括机组改造成本、调峰市场交易成本、售电收益损失、深调状态发电成本增量和系统弃电成本五部分费用在内的火电机组灵活性改造广义成本模型 ...

Use of carrion fly iDNA metabarcoding to monitor invasive and native mammals
Conservation Biology, Volume 37, Issue 5, October 2023., 2023 Abstract Severely fragmented habitats increase the risk of extirpation of native mammal populations through isolation, increased edge effects, and predation. Therefore, monitoring the movement of mammal populations through anthropogenically altered landscapes can inform conservation. We used metabarcoding of invertebrate‐derived DNA (iDNA) from carrion

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 ...

Family Process, Volume 62, Issue 2, Page 534-556, June 2023., 2023 Abstract Study of change mechanisms is important to advance theory development and to reveal the active components that make a critical difference in treatment. Improved outcomes in a randomized controlled trial that favored Congruence Couple Therapy (CCT) vs individual‐based Treatment‐as‐Usual (TAU) were correlated within each group.

Disasters in the Anthropocene: a storm in a teacup?
Disasters, Volume 47, Issue 2, Page 298-319, April 2023., 2023 Dramatic alterations to the natural environment due to human activity have produced a permanent rupture in the Earth system; the relative stable epoch of the Holocene has given way to a volatile Anthropocene. Acceptance of these claims means that we now live in this altered physical reality, inviting us to rethink how we conceptualise disasters.

From zero to villain: Applying narrative analysis in research on organizational reputation
European Policy Analysis, Volume 7, Issue S2, Page 405-424, Summer 2021., 2021 Abstract What narratives accompany the emergence of a negative reputation? I combine research on public organizations’ reputation with narrative analysis. Narratives offer multiple benefits to reputational research, playing an important role in human cognition and comprising social constructions of both organizations and other actors.

Evaluating the social and ecological effectiveness of partially protected marine areas
Conservation Biology, Volume 35, Issue 3, Page 921-932, June 2021., 2021 Abstract Marine protected areas (MPAs) are a primary tool for the stewardship, conservation, and restoration of marine ecosystems, yet 69% of global MPAs are only partially protected (i.e., are open to some form of fishing). Although fully protected areas have well‐documented outcomes, including increased fish diversity and biomass, the effectiveness ...

火电机组灵活性改造与输电网规划多阶段联合决策方法 [PDF]
全球能源互联网, 2021 大规模风电并网对电力系统灵活性提出了很高的要求。针对大规模风电并网背景下的消纳问题提出了一种火电机组灵活性改造与输电网规划多阶段联合决策方法。通过将火电机组灵活性改造纳入输电网规划优化决策,统筹优化系统灵活性及传输能力,促进大规模风电并网消纳。基于规划周期内负荷功率预测曲线,并计及风电时序出力不确定性情景,以输电网建设投资成本、火电机组灵活性改造成本以及发电总成本、弃风电成本折现值之和最小为目标,以系统正常运行状态以及N ...
