+The main objective of REVUB is to model how the operation of hydropower plants can be hybridised with variable solar and wind power (VRE) plants, allowing the combination of hydro with VRE to operate "as a single unit" to provide reliable electricity supply and load-following services. The model can be used, for instance, in due diligence processes for power plant financing.
 
 This model was first introduced in the paper "Smart renewable electricity portfolios in West Africa" by Sterl et al. (2020; https://www.nature.com/articles/s41893-020-0539-0); hereafter referred to as "the publication". It has since been used for several more peer-reviewed publications.

 It reads in an Excel file with overall modelling parameters ("parameters_simulation.xlsx"), and several Excel files with tabulated time series and other data ("data_xxx.xlsx"; in this case, these datasets are themselves the results of external computations, described in the publication).
