A Study on Designing Off-grid System Using HOMER Pro - A Case Study

Abstract

Nowadays, grid parity has been achieved in some of countries. In accordance, the most of countries make efforts to reduce carbon emission by expanding renewable energy to the system. For example, in South Korea, they have initiated Energy Independent Island project, which pursues no fossil fuel usage to supply electricity demand in remote island. However, it needs proper economic assessment process even though renewable energy price keeps decreasing. In this paper, we model 3 arbitrary power systems by referring system data of remote islands of South Korea and perform optimization simulation using HOMER Pro to follow economic assessment process.
