Microgrid Technologies for Remote Indonesian Islands

Project summary

Tech-IN is aimed at overcoming the challenges associated with the large-scale deployment of renewable-based microgrids (MGs) in the hazardous environment of the Indonesian Islands that is prone to severe natural disasters (NDs). Tech-IN’s goal is twofold: it will cope with two main concerns in Indonesia: (i) to increase the renewable energy while reducing the fossil fuel dependence, and (ii) bringing electricity to remote places and Islands. Secondly, it will provide high levels of resiliency and availability of electricity supply in front of natural disasters.

Indonesia is suffering 3,622 NDs including tornadoes, floods, and landslides occurred across the country in 2019. Each time a disaster strikes, it not just only causes an interruption in electricity supply, it also compromises telecommunication, transportation, and health sector infrastructures interconnected with the electricity network. Therefore, a resilient electrification system capable to deal with NDs is highly demanded in the Indonesian context and renewables-based scalable MGs can be the key solution in this regard.

Tech-IN will develop new MG architectures with high levels of resiliency and scalability. Three layers of granularity will be developed. The potential of MGs deployment will be investigated for grid-connected and islanded applications by considering two case studies: Lombok and Medang Islands. Moreover, based on the techno-socio-economic analysis of the Indonesian energy sector, control architectures, and reconfigurable energy management systems will be developed for all three levels of granularity.


First annual report:
The WP1 - Techno-socio-economic feasibility of MGs in Indonesia has been completed and the relevant three milestones were achieved with three deliverables and two potential publications. The outcomes of the WP1 are as follows: 1) Identification of the technical requirements for the energy system on Lombok area. 2) An energy sector analysis has been conducted. Several socio-economic aspects for the entire electricity supply chain included electricity consumption, generation, transmission & distribution, with investigation of distributed energy resources was conducted; 3) The load patterns for the normal and emergency situations were investigated and identified. A clustering algorithm is applied to perform the identification of normal and emergency clusters, based on the historical ½-hourly power consumption data from 2012 until 2022 for Lombok provided by our local partners.
The Task 2.1 - Planning, control, and integration of Ad-hoc MGs for emergency camps of WP2 is completed and the milestone 2.1 is achieved with one deliverable and one potential conference paper. The outcomes of the T2.1 are as follows: 1) Three Ad-hoc MGs and two Ad-hoc MGs are designed for the clinics in the Mandalika and Gili Trawangan areas respectively; 2) Voltage and frequency stabilization control strategy and PV-battery coordinated control strategy are developed for individual Ad-hoc MG; 3) Plug & play and quasi-SoC balancing control are proposed for the parallel connected Ad-hoc MGs.
