Hybrid2 - a Versatile Model of the Performance of Hybrid Power Systems

In 1993, the National Renewable Laboratory assessed the available tools for predicting the long-term performance of hybrid power systems. No single tool was found to be capable of modeling the full range of hybrid power technologies being considered for the 1990s and beyond. As a result, NREL prepared a specification for a new model, called HYBRID2; model development by NREL and the University of Massachusetts began in 1994. HYBRID2 will have a user-friendly windows-based interface. A library of input data files will be provided with the model so that users can more readily model new applications by making incremental changes to existing project, power system, or component files. HYBRID2 will provide significant flexibility as to the configuration and dispatch (control) of the power system to be modeled. Both graphical and tabular output of results will be provided. The model is intended to provide comparisons of competing technology options on a level playing field. Initial testing of HYBRID2 is now underway.
