This Volume II report is a targeted extension of the CEATI SOIG 0541 Microgrid Scoping Study, Volume I. This report focuses on two key areas: (1) the assessment of techno-economic software models for remote community microgrid economic modeling, and (2) the development of a techno-economic model for economic evaluation and linear optimization of utility distribution microgrids.
The report compares two microgrid feasibility software packages, HOMER and DER-CAM, for remote community microgrids. The report uses primary and secondary sources to provide an overview of remote-community microgrid-modeling requirements and the applicability of each software package. The report compares the software user interfaces, analysis engines, basic capabilities, scope, and results for asset optimization.
The report also presents a linear optimization tool, developed to optimize the dispatch of microgrid assets, to support design and economic analysis of potential utility distribution microgrid projects. The Excel-based model consists of two key modules: the Asset Optimization Module, for optimized interval dispatch of microgrid resources, and the Pro Forma Module, which utilizes the outputs of the optimization as inputs for financial analysis over the project life. The report describes this model in detail, including the inputs and outputs. The sample model run results and sensitivities are presented to illustrate representative utility-distribution microgrid scenarios. The results of this analysis provide insights for users to consider in subsequent analyses of potential utility-distribution microgrid projects.
