Introduction

This dataset provides the daily, monthly, and annual complementarity between floating photovoltaics (FPV) and hydropower for select locations in the United States. The metrics used are the stability coefficient and Pearsons coefficient. An optimization using the generic algorithm provides the optimal capacity for theoretical FPV sites to achieve the maximum stability in the combined generation with hydropower.

To run the code

To run the code, please unzip "Data.zip" and "Metrics.zip" files to the same root as other jupyter notebooks first. One can follow all jupyter notebooks from 1 to 5 for the whole process of complementarity analysis in the study. That is, 1. determine sites analyzed; 2. fetch USGS discharge data and post-processing the dataset obtained; 3. estimate floating PV and hydropower generation profile for analyzed sites and years; and 5. use generic algorithm (GA) to optimize FPV nameplate capacity by maximizing the stability coefficient. One can also run specific script based on requirement.

All orginal and generated datasets can be also find in "Data (Generateed Files).zip" and "Metrics (Generated Files).zip".
