IM3 Projected U.S. Western Interconnection Grid Stress Dataset

This dataset provides projected grid stress and reliability results (including all model inputs and outputs from GO WEST and TEP) for Integrated Multisector, Multiscale Modeling (IM3) Phase 2 simulations across eight different scenarios for the U.S. Western Interconnection through 2055. The scenarios include combinations of two Shared Socioeconomic Pathways (SSP3 and SSP5) with four high-resolution climate projections specific to the United States from a set of Thermodynamic Global Warming (TGW) simulations. These climate projections include "hotter" and "cooler" variants for two Representative Concentration Pathways (RCP4.5 and RCP8.5). The resulting eight simulations are:

rcp45cooler_ssp3
rcp45cooler_ssp5
rcp45hotter_ssp3
rcp45hotter_ssp5
rcp85cooler_ssp3
rcp85cooler_ssp5
rcp85hotter_ssp3
rcp85hotter_ssp5
GO WEST is an open-source power grid modeling framework for the U.S. Western Interconnection, which allows users to tailor the model depending on their research study and science questions. It covers 28 balancing authorities (BAs) and 12 states in U.S. Western Interconnection. GO WEST allows users to select different number of nodes and come up with a simplified network by utilizing 10,000 nodal topology of the U.S. Western Interconnection (ACTIVSg10k). Users can select different number of nodes, mathematical formulations (linear programming vs. mixed-integer linear programming), transmission line limit scaling factors, and hurdle rate scaling factors. GO WEST offers a unit commitment and economic dispatch (UC/ED) module to simulate grid operations on an hourly scale. In this sense, users can calibrate and validate their model versions by comparing model outputs to historical datasets. 
TEP is an open-source transmission capacity expansion model, built on the GO WEST framework. It utilizes linear programming to optimize transmission capacity addition investment on existing lines within the GO WEST framework. The TEP model only increases the thermal capacity of existing transmission lines and does not add new lines to the system, which leaves the topology preserved. In order to use TEP model, users need to create scenarios with the GO WEST framework.

本数据集提供了截至2055年，美国西部互联电网的多部门多尺度集成建模（Integrated Multisector, Multiscale Modeling, IM3）第二阶段仿真的投影网格应力与可靠性结果，包含GO WEST与TEP的全部模型输入与输出，共覆盖8种不同情景。这些情景由两种共享社会经济路径（Shared Socioeconomic Pathways, SSP3与SSP5），与4套源自热力学全球变暖（Thermodynamic Global Warming, TGW）仿真集的美国专属高分辨率气候预测组合而成。这些气候预测针对两种典型浓度路径（Representative Concentration Pathways, RCP4.5与RCP8.5）分别设置了“更暖”与“更冷”两种变体。最终的8组仿真为：
rcp45cooler_ssp3
rcp45cooler_ssp5
rcp45hotter_ssp3
rcp45hotter_ssp5
rcp85cooler_ssp3
rcp85cooler_ssp5
rcp85hotter_ssp3
rcp85hotter_ssp5
GO WEST是面向美国西部互联电网的开源电网建模框架，支持用户根据研究场景与科学问题定制模型。该框架覆盖美国西部互联电网的28个平衡机构（balancing authorities, BAs）与12个州。GO WEST可依托美国西部互联电网的10000节点拓扑（ACTIVSg10k），通过选择不同节点数量生成简化电网网络。用户还可自定义节点数量、数学求解形式（线性规划vs混合整数线性规划）、输电线路限值缩放因子与门槛值缩放因子。GO WEST内置机组组合与经济调度（unit commitment and economic dispatch, UC/ED）模块，可按小时尺度模拟电网运行，支持用户通过将模型输出与历史数据集对比，对模型版本进行校准与验证。
TEP是基于GO WEST框架开发的开源输电扩容规划模型，采用线性规划对GO WEST框架内现有线路的输电容量扩容投资进行优化。该TEP模型仅对现有输电线路的热稳定容量进行提升，不会向系统中新增线路，因此可保留原有电网拓扑。使用TEP模型前，用户需依托GO WEST框架创建仿真情景。
