Exergy and environmental analysis of oscillating wave energy converter hybrid with other renewable energy resources: A case study

Abstract

ABSTRACT In order to evaluate the hybrid renewable configurations in diverse applications, this inquiry tries to propose a novel decision-making procedure. The open-source WEC dynamics simulator, exergetic assessment, and Hybrid Optimization Model for Electric Renewables Pro software are integrated. In this innovative method, the exergy of the component is calculated using MATLAB software. Technical analysis for the goal of rural electrification is examined in this work. Thus, several integrated energy systems are technically researched. This study deals with the exergy, environmental, and exergoenvironmental analyses of the hybrid renewable energy system, to assess its performance and environmental impact when operating on Siri Island. In the photovoltaic solar panels, wind turbines, wave energy converters, diesel generators, and batteries set up, the total exergy efficiency and exergy destruction rate were 18.4% and 7.24 106 kWh/year, respectively. Additionally, it was discovered that the wave energy converter was responsible for 5% of the total energy wasted. Photovoltaic solar panels, wind turbines, and wave energy converters all have mean annual exergy efficiencies calculated to be 11.7%, 13.1%, and 20.8%, respectively. Environmental and exergoenvironmental analyses illustrate that the off-grid scenario decreases CO2 emission by 95% compared to the on-grid scenario and utilizing diesel generators increases the exergy stability factor of the energy system. The suggested decision-making procedure can be a potent and reliable instrument for analyzing any hybrid renewable arrangement from a technological standpoint.
