Dimensionamiento optimo para pequeños sistemas hibridos aislados aplicado en las islas Galapagos

Abstract

Electrification in the Galapagos Islands is one of the main objectives of the supplying companies and governments in general, climate change, encourage the use of locally available sources of renewable energy, avoiding the use of diesel generators. In this context, this research seeks an optimal design of small units (photovoltaic panels and wind turbines), which is technically feasible and economically optimal, for the analysis data published by the corresponding government body are used. To dimension a hybrid system based on photovoltaic panels and wind turbines with storage by means of batteries, it is necessary to identify all the possible combinations that offer a certain level of reliability and efficiency, the best option is acquired when valuing the economic cost of each of the possibilities for the same level of reliability. For the determination of the demand, the equipment of a house in the Galapagos Islands is considered, to perform the economic analysis, based on the cost of energy ($ / kWh) is established to estimate the consumption of the electric service in the Galapagos Islands. The annual per capita consumption of the inhabitants of the Galapagos Islands is 1628 kWh / inhabitant. Simulation and optimization of a hybrid system using the HOMER software was executed to determine the configuration for the hybrid system. The model has been simulated for one year; sensitivity analysis is performed to understand the effect of various uncertainties on the net present cost. The conclusions indicate the viability of the optimal hybrid system, from a technical-economic criterion for the supply of energy.
