摘要

Hybrid renewable energy systems combining wind and solar generation with battery storage are essential for reliable grid integration, but optimal sizing and dispatch strategies remain computationally challenging. We present a mixed-integer linear programming (MILP) framework coupled with vanadium redox flow battery (VRFB) degradation modeling to optimize hybrid wind-solar-VRFB systems for three grid-connected microgrids in Inner Mongolia, Rajasthan, and Patagonia. The optimized configurations achieve renewable energy fractions of 78-92% with levelized cost of electricity (LCOE) of $0.048-0.062/kWh. VRFB systems sized at 4-6 hours of rated power provide superior cycle-life economics compared to lithium-ion alternatives for daily energy shifting, with projected 20-year capacity retention of 85% versus 62% for LiFePO₄ under equivalent cycling profiles.
