Abstract
Energy sustainability has become one of the main issues in power system planning in the Indonesian archipelago system, which has many small, isolated systems. For that purpose, green and sustainable generation expansion planning (GEP) procedures based on local energy resources is required. GEP is a necessary procedure for fulfilling electricity demand, which determines the generating units to be installed within a specified time horizon with minimal total costs as the objective function. This study uses GEP considering the interconnection option among the existing small scattered generation systems in Maluku: the isolated Ambon, Seram, Haruku, and Saparua systems. With interconnection, the utilization of local renewable energy sources would be increased, especially biomass, which has abundant potential in these areas. The GEP was simulated in the PLEXOS environment using mixed-integer linear programming (MILP). For comparison purposes, there were interconnection and isolated system scenarios. The results showed that the interconnection system would have a high share of a renewable energy source (RES) of up to 54% in 2050, most of which is biomass as the primary local energy source. The interconnection system scenario met the LOLP criteria and had a lower reserve margin and total costs than the isolated scenario, with USD 773.7 million.

Published: 4 March 2022Maintaining energy sustainability has become one of the main issues in electrical power system planning, especially considering the low economic development of some areas and global environmental issues [1]
These regulations were formulated on the basis of the Paris Agreement and the Kyoto Protocol, as the Government of the Republic of Indonesia has committed to reducing greenhouse gas emissions by 29% by 2030 [24,25]
Implementing long term generation expansion planning by considering the various primary energy resources and interconnection options between isolated areas is necessary to increase the full potential of biomass, solar and wind energy so that the development of a sustainable area/region can be ensured, especially in the scattered and isolated system of the eastern part of Indonesia, as presented in [30]
Summary
Maintaining energy sustainability has become one of the main issues in electrical power system planning, especially considering the low economic development of some areas and global environmental issues [1]. Implementing long term generation expansion planning by considering the various primary energy resources and interconnection options between isolated areas is necessary to increase the full potential of biomass, solar and wind energy so that the development of a sustainable area/region can be ensured, especially in the scattered and isolated system of the eastern part of Indonesia, as presented in [30]. The GEP procedure should include the option of interconnection with the neighboring systems to optimize the potential of the local energy resources and increase the system’s reliability. In another study in Kenya [37], the researcher used WASP-IV to solve GEP problems by carrying out renewable energy integration and least cost GEP to achieve security and continuity in the supply of electrical power systems. The isolated system scenario resulted in a RES energy mixed of 51% in 2050
