Techno‐economic evaluation of renewable energy systems combining PV‐WT‐HKT sources: effects of energy management under Ecuadorian conditions

Abstract:

Sustainable development reached a new energy paradigm in recent decades, by promoting renewable generation technologies. The present study performs a techno‐economic analysis of several hybrid energy systems that combine wind generators, photovoltaic systems, hydrokinetic turbines, lead acid batteries, and diesel generators in southern Ecuador. From real data, the sizing optimization of each renewable system was done under three proposed energy control algorithms. Then, the combinations of renewable systems are compared based on costs, energy, and environment. Additionally, this study includes several sensitivity analyzes varying the cost of the components and fuel, minimum state of charge in batteries, scaled electric load and time step to better understand the impact caused in each renewable hybrid system. The results show that a system composed of three renewable sources under load …
