Energy-Flow-Environment Linkage Map

Understanding how flexibility in environmental requirements can facilitate co-optimization of hydropower production outcomes and environmental outcomes is critical for future grid decision-making and operations as renewable energy resources increase. The environmental and power system outcomes connectivity linkage maps presented here provide a framework for conceptually and quantitatively linking power system outcomes to environmental outcomes through hydropower flow decisions. The Executive Summary Map serves as a starting for exploring the links between hydropower system performance outcomes and environmental outcomes. The centralized topic is “Flow from Hydropower System,” and connects the hydropower operations through “Flow through turbines” and “Non-turbine flows”, and to environmental outcomes through Reservoir elevation” and “Flow downstream of the hydropower system”. To the left of these central topics, “Hydro-mechanical operations” are linked through “Hydro-electrical operations” to “Hydropower performance outcomes” (“Reliability”, “Resilience”, “Revenue”, “Emissions”). On the right, environmental outcomes are grouped together by their physical location: “Upstream Outcomes” (“Upstream geomorphology”, “Upstream recreation”, “Upstream habitat”, “Upstream biota and biodiversity”, “Upstream water quality and greenhouse gas”), Outcomes relevant to both “Upstream/downstream or dam interface” (“Navigation”, “Dam safety and maintenance", “Human health”, “Water supply”, “Flood control”, ”Fish passage”), and “Downstream outcomes“ (e.g., “Downstream geomorphology”, “Downstream recreations”, “Downstream habitat”, “Downstream biota and biodiversity”, “Downstream water quality and greenhouse gas”). Each of these subtopics (e.g., “Hydro-mechanical operations”, “Hydro-electrical operations”, “Upstream geomorphology”, “Upstream recreation”) is further explored through their corresponding submaps. The “Read Me” file provides more detail information on map navigation. The “Models and tools database” file provides detailed information of models and tools presented in the maps.

随着可再生能源装机与并网规模持续扩大，探究环境要求的灵活性如何助力水电生产效益与环境效益的协同优化，对未来电网决策与运行至关重要。本文所呈现的环境与电力系统效益关联图谱，提供了一套可通过水电流量调度，从概念与定量层面将电力系统效益与环境效益相衔接的分析框架。本数据集的执行摘要图谱（Executive Summary Map）可作为探索水电系统绩效效益与环境效益之间关联的起点。图谱的核心主题为「水电系统流量」，其通过「水轮机过流量」与「非水轮机过流量」关联水电运行环节，并通过「水库水位」与「水电系统下游流量」衔接至环境效益维度。在核心主题左侧，「水动力机械运行」（Hydro-mechanical operations）通过「水电运行」（Hydro-electrical operations）关联至「水电系统绩效效益」，后者涵盖「可靠性」「韧性」「收益」与「排放」四类核心指标。在核心主题右侧，环境效益可按物理区位划分为三大类别：一是「上游效益」（Upstream Outcomes），包含「上游地貌」「上游休闲」「上游栖息地」「上游生物群与生物多样性」「上游水质与温室气体」；二是「上下游/坝体界面相关效益」（Outcomes relevant to both "Upstream/downstream or dam interface"），涵盖「航运」「大坝安全与维护」「人类健康」「供水」「防洪」「鱼类洄游通道」；三是「下游效益」（Downstream outcomes），例如「下游地貌」「下游休闲」「下游栖息地」「下游生物群与生物多样性」「下游水质与温室气体」。上述各子主题（如「水动力机械运行」「水电运行」「上游地貌」「上游休闲」等）均可通过其对应的子图谱开展深入解析。「Read Me」文件可提供图谱导航的详细说明；「模型与工具数据库」（Models and tools database）文件则详细介绍了图谱中呈现的各类模型与工具。
