A Comprehensible Technical and Financial Methodology for DC/AC Microgrids Design

This paper unveils a comprehensible technical and financial methodology for designing DC isolated and DC/AC interconnected microgrids. The technical analysis is founded on the IEEE Standards 1562 and 1013 for PV and Battery sizing, respectively. The financial analysis is based on an optimal and deterministic approach. Both technical and financial approaches are deeply tackled in a simulated environment which is conducted in Matlab & Simulink™ and HOMER Pro©, respectively, demonstrating that the methodology is effective to quantify the feasibility and viability of the microgrid design. As consequence, a measure of performance is established depending on its profitability. Finally, the effectiveness of the proposal is corroborated on an actual study case in Janitzio Island, Mexico.
