Análisis del potencial energético de un sistema híbrido solar eólico mediante modelado y simulación para su implementación en la zona rural de Atahualpa

Abstract

This research analyzes the energy potential of a hybrid solar-wind system for implementation in the rural area of Atahualpa, in the province of Santa Elena, Ecuador. Using real meteorological data from NASA POWER (year 2025) and a model developed in MATLAB, the hourly behavior of a system consisting of 20 kWp solar panels, a 10 kW wind turbine, and 30 kWh battery storage was simulated. The system was designed to meet the typical daily demand of a coastal rural household (approximately 18 kWh/day). The results show that the system generates 4,619 kWh of solar energy and 7,639 kWh of wind energy annually, totaling 12,258 kWh from renewable sources. The average energy autonomy reaches 71.77 %, with the battery state of charge (SOC) remaining mostly above 40 % throughout the year and peaking higher during sunnier months. The levelized cost of energy (LCOE) is estimated at 0.08 USD kWh, which is lower
