The PLTS Pertamina RU II Dumai Solar Power Plant has a capacity of 2 MW, featuring an on-grid system comprising 16 homogeneous arrays. In this research, a PLTS system simulation developed based on existing technical data from the PLTS Pertamina RU II Dumai. The PLTS system, created using Simulink in MATLAB software, consists of a single array system, with 8 sub-arrays. Each subarray is made up …
