doi: "https://doi.org/10.11578/dc.20250402.1"
description: "This repository contains code and data for performing a siting analysis\
  \ of long-duration energy storage (LDES) in the 5-bus and RTS systems using the\
  \ Sienna suite developed by the National Renewable Energy Laboratory for production\
  \ cost modeling (PCM). This analysis involves moving the LDES component to different\
  \ buses in the system, running a simulation, and considering the production cost\
  \ of the simulation. Different system configurations are also analyzed with these\
  \ scripts (such as moving load or renewable dispatch generators to different buses)\
  \ to observe the impacts the system configuration has on optimal siting. This repository\
  \ contains three sub directories discussed below. Both the 5-bus and RTS systems\
  \ have two different initial configurations for the renewable energy components\
  \ in them, one that is predominantly PV-driven and one that is predominantly wind-driven.\n\
  \nSienna suite can be found here: https://github.com/NREL-Sienna"
