Labtek VI Building, Bandung Institute of Technology is implementing a smart building system, a building that can manage resources efficiently and environmentally friendly by utilizing new and renewable energy. In addition, the need for electrical energy still relies on fossil fuels sourced from the PLN electricity network, which in fact is increasingly scarce and not environmentally friendly so that the search for alternative energy to meet the needs of electrical energy continues to be developed by utilizing new and renewable energy sources. Hybrid PLTS will be designed in this final project which is a system integration consisting of combining PLTS, PLN, and batteries so that energy supply does not only depend on PLN. That way, PLTS can be installed in the Labtek VI Building to become an energy reserve if the PLN electricity network is not operating. And the system can be integrated to supply server rooms that require continuous electricity. The simulation begins with finding the largest output energy from poly-crystalline and mono-crystalline solar modules in PVsyst software. Then, a simulation of the performance of the PLTS hybrid system is carried out when resilience and reliability problems occur in the HOMER Grid software with 2 variations of battery types, namely Valve Regulated Lead Acid (VRLA) batteries and Lithium Ion batteries along with variations of the minimum SOC battery, which is 30%, 40%, and 60%. The results of the simulation and analysis of the energy and economic aspects that were carried out resulted in a system design recommendation using a mono-crystallin type solar module and an LG Chem RESU 10H 9.8 lithium ion type battery with a minimum SOC of 30%. This is because the simulation is carried out under ideal conditions where the mono-crystalline type module will produce the most energy output. Battery analysis is carried out with endurance, safety, and Levelized Cost Of Energy (LCOE) of the designed system scenario. This design has a longer battery life in the grid than VRLA batteries. The LCOE of this design is Rp2.402,08. The implementation of this hybrid PV mini-grid system design can be adjusted to the desired budget, durability, and reliability.
