Abstract
In remote areas, extending a power line to the primary electricity grid can be very expensive and power losses are high, making connections to the grid almost impossible. A well-designed microgrid that integrates renewable energy resources can help remote areas reduce investment costs and power losses while providing a reliable power source. Therefore, investigating the design of an independent and economically practical microgrid system for these areas is necessary and plays an important role. This paper introduces a design procedure to design an isolated microgrid using HOMER software (HOMERPro 3.14.5) for remote areas. In Vietnam, due to the obstruction of the mountainous terrain or the isolated island location, many remote areas or islands need electrification. A simple case study of a hybrid system with a 60 kW peak load demand on Con Dao island in Vietnam is used to illustrate the proposed design method. Specifically, a hybrid system that includes a PV system, batteries, and a diesel generator is designed. To provide the full information of the designed hybrid system designed, each solution is analyzed and evaluated in detail according to the sensitivity parameters.
Highlights
The selected model consists of a 40 kW diesel generator, a 67.5 kW solar power system, one 20–40 kWh battery, and a 22.2 kW power converter
The total optimal system cost was USD 677,663, less than the total cost of designing a basic system consisting of only a diesel generator and a battery
Hybrid Optimization Model for for Electric (HOMER) will analyze different scenarios based on the load demand and the given inforClean Technol. 2021, 3 mation of the considered system
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Energy consumption has increased quickly due to the fast development of the global economy. The fossil energy resources such as coal, oil, and natural gas cannot be recreated and pollute the environment [1]. To address these issues, new renewable energy resources have become a key factor of choice. In developed countries and regions, renewable energy development strategies have been developed to maximize the use of renewable energy resources and increase energy efficiency [2,3,4]
