Military Microgrid in Indonesia

One of the tasks of military forces is to defend the country. Furthermore, Indonesia has more than 300.000 people serve as a military force like army, navy, or air force and has to be ready anytime to serve the country. On the other hand, the usage of electricity in military activity is very important. Thus, having reliable and secure sources is mandatory. In addition, one of the advantages of a microgrid are reliability, security, and also clean energy, so having a military microgrid in Indonesia also means that it will help to achieve the Indonesian government target to increase 23% of renewable energy share by 2030. This paper discusses the overview of military microgrids and also a study case with techno-economic calculation for one of the military bases in Indonesia. By Importing the solar data, load data, diesel and also Photovoltaic (PV) data, HOMER Pro search the best combination of feasible solution with constrain given. The result proposes four different architecture combination of PV, Diesel, Battery on grid and off grid. The cheapest solution with backup is system 4 where the combination is consisting of PV and battery with on grid system with LCOE USD 0.024 and serve the 1124,86GWh/year load.
