Development of power system infrastructure model for the island communities: A case study in a remote island of Indonesia

Electricity infrastructure for a remote island needs to be given attention for the security and wellbeing of island communities. The purpose of this study is to develop a model of renewable energy infrastructure based on renewable energy available locally in an archipelago region. This research is a case study for Kokorotan Island that located in eastern Indonesia region of Talaud Island regency of North Sulawesi province bordering with Philippines. The research method used is primary and secondary data collection, data analysis using software HOMER. Based on the simulation results, a model of renewable energy-based power generation system for the community's electric energy needs in Kakorotan Island is obtained. The cost of generating electrical energy with renewable energy is relatively high then it is necessary to have policies and strategies for the development of power infrastructure for the sake of the energy security of island communities in Indonesia.
