OPTIMIZATION OF A STAND-ALONE HYBRID WIND/SOLAR GENERATION SYSTEM FOR LIFESPAN EXTENSION

The work presented in this thesis focuses on the optimization of a hybrid wind/solar system with energy storage for equipment lifespan extension. In general, electrical equipment is exposed to operational disturbances that result in temporary or permanent damage to the equipment. This study analyzes each component of the system, identifies several potential operational disturbances, and subsequently proposes a method to minimize the conditions that create or cause such effects. These conditions are minimized by solving an optimization problem that calculates the sources’ supply set points at which the system’s operational disturbances are minimized. Scenarios with different operating conditions to verify the performance of the proposed formulation along with illustrative examples in terms of case studies are also presented. This abstract accurately represents the content of the candidate’s thesis. We recommend its publication. Signed Fernando Mancilla-David Signed Alexander Engau
