Overview

PREP-SHOT (Pathways for Renewable Energy Planning coupling Short-term Hydropower OperaTion) is a transparent, modular, and open-source energy expansion model, offering advanced solutions for multi-scale, intertemporal, and cost-effective expansion of energy systems and transmission lines. It's developed by Zhanwei Liu and Xiaogang He from the PREP-NexT Lab at the National University of Singapore.

Key Features

• Optimization model based on linear programming for multi-zone energy systems.
• Cost minimization while meeting given demand time series.
• Adjustable operation on hourly-spaced time steps.
• Input data in Excel format and output data in NetCDF format using Xarray.
• Support for multiple solvers like Gurobi, CPLEX, MOSEK, and GLPK via Pyomo.
• Allows input of multiple scenarios for specific parameters.
• A pure Python program, leveraging pandas and Xarray for simplified complex data analysis and extensibility.

Getting Started

This section includes a brief tutorial on running your first PREP-SHOT model.

1. Clone the repo

   git clone https://github.com/PREP-NexT/PREP-SHOT.git

2. Create the Conda Environment and install the dependencies

   conda env create -f prep-shot.yml

3. Activate the Conda Environment

   conda activate prep-shot-test

4. Run your first model

   python run.py

This example is inspired by real-world data. For a detailed elaboration of this tutorial, check out the Tutorial Page in our documentation.
