Optimized Hybrid Power System Configuration for The First Phase of Dedieselization Programs

To boost renewable energy utility for achieving the target of 23% renewable energy mix by 2025, PT PLN (Persero) launches the diesel conversion to renewable energy program that well-known as Dedieselization program. For the first phase, PLN locks target to convert 225 MW of diesel power plant in 200 locations to the renewable energy power plant. To align renewable energy potential utilization with affordable cost and to qualify with data confidentiality, this paper will figure out optimized hybrid power system configuration for three sampling islands: Island A, Island B, and Island C. These three islands will deal with three considered aspects: low Levelized Cost of Electricity (LCOE), less capacity shortage, and less land utilization. Simulation using HOMER Pro for configuration without diesel utilization deliver results that capacity shortage still occurs. Meanwhile, a hybrid configuration that utilizes a diesel plant delivers zero capacity shortage. Furthermore, scoring that refer to simulation result and optimized parameter conclude that Hybrid PV/BESS/Diesel is the most optimized configuration for Island A and Island B. Otherwise, Island C has Hybrid PV/Diesel as the most optimized configuration. Finally, this paper concludes that any dependency on diesel utilization to succeed Dedieselization program to deals with low LCOE, zero capacity shortage, and less land utilization.
