The Masterplan for Developing Electricity Systems for Archipelagic Area by Considering Local Energy Resources: A Case Study of Maluku Islands

Power System Planning Assessment for Optimizing Renewable Energy Integration in the Maluku Electricity System

“…The workflow of the assessment is shown in Figure 4. The data needed to assess the power system planning include the existing transmission system, the load forecasting result, the additional generating unit, and the proposed transmission line candidates, which are provided by the previous study [4,8]. After all of the data are collected, the power system is then modeled for a particular year in the commercial power system simulation package DIgSILENT PowerFactory [33], the user interface of which is presented in Figure 5.…”

“…The proposed Maluku power system plan was obtained from our previous work on the design of the Eastern Indonesia Masterplan, as presented in [4], and the generation and expansion planning of the Ambon-SHS system, including the decision to use interconnection, as presented in [8]. These papers show that the most economical plan will be achieved if the Ambon-SHS are connected through a submarine interconnection system in 2025.…”

“…The construction of the transmission line between subsystems follows two plans, namely the plan based on Indonesia's 2019-2028 Electricity Procurement Plan [5] and the power system planning obtained in previous studies [4,8]. Figure 9 shows the transmission line candidates for the Maluku system from 2020 to 2050 and the single line diagram is shown in Figure 10.…”

“…The different priorities among islands concerning electricity infrastructure planning also contribute to the low average electricity consumption. In addition, the difficulties in providing electricity to eastern Indonesia are related to social, geographical, and demographic conditions [4], as it consists of over 17,000 islands. The majority of the islands are in the eastern part of Indonesia and are divided into two major regions, Maluku and Papua, which are still underdeveloped when compared to other regions.…”

“…Maluku has abundant potential for renewable energy sources, such as hydropower, wind, solar, and biomass. In addition, Maluku has substantial biomass energy resources, with a potential production forest area of 13,944.16 km 2 [4,8]. Some of the benefits of biomass energy include empowering the surrounding population to reduce poverty, reducing emissions using carbon-neutral technology, restoring underutilized land, and turning the land into a water retention area [9].…”
