Abstract
Peranan energi baru terbarukan dalam sasaran Kebijakan Energi Nasional
2025 sebesar 5% meliputi energi air, angin, matahari, biomassa, dan nuklir.
Diantara sumber-sumber energi tersebut, energi matahari memiliki banyak
keuntungan yaitu tidak akan pernah habis, tidak menghasilkan zat beracun, dan
tidak merusak alam akibat instalasinya. Usaha yang paling signifikan dalam
peningkatan penggunaan energi baru terbarukan adalah dengan membangun
instalasi Pembangkit Listrik Tenaga Surya (PLTS) dalam skala besar dan
terhubung ke sistem jejaring listrik (grid). Pada penelitian dirancang PLTS
berkapasitas 100 kW terhubung ke sistem distribusi 20 kV melalui Cascaded HBridge
Multilevel Inverter (CHB-MLI). Multilevel inverter jenis CHB-MLI
membutuhkan sumber-sumber searah atau Direct Current (DC) terpisah untuk
tiap-tiap H-bridge inverter. Penyediaan sumber-sumber DC dari PLTS dengan
konfigurasi sel surya yang terpusat yang dipisah dengan menggunakan
transformator multibelitan untuk selanjutnya disearahkan menggunakan rectifier.
Sistem dilengkapi dengan Maximum Power Point Tracker (MPPT) untuk
menghasilkan daya maksimum pada nilai radiasi dan temperatur yang berbedabeda.
Hasil simulasi menunjukkan CHB-MLI mampu mentransfer daya dari PV
ke grid sebesar 95,5 kW dengan efisiensi tracking sebesar 93,6%. CHB-MLI
memiliki kandungan harmonik tegangan sebesar 0,046%.

The role of renewable energy in the National Energy Policy 2025 is 5%
include water, wind, solar, biomass, and nuclear energy. Among these energy
sources, solar energy has many advantages that will never run out, does not
produce toxic, and does not damage the nature due to its installation. The most
significant effort to increase the use of renewable energy is installing of Solar
Power Plant (SPP) in a large scale and connecting to the electrical network system
(grid). In this study, it has been designed a 100 kW SPP connected to the 20 kV
distribution system through Cascaded H-Bridge Multilevel Inverter (CHB-MLI).
Multilevel inverter type CHB-MLI require Separated Direct Current (DC) sources
(SDCS) for each H-bridge inverter. SDCS are provided by centralized solar power
plant which is separated by multi-winding transformer to rectified using rectifier.
Maximum Power Point Tracker (MPPT) is require to produce maximum power at
varying radiations and temperatures. The simulation results show the CHB-MLI is
capable of transferring power from the PV to the grid 95,5 kW with a tracking
efficiency 93,6%. Total harmonics distortion of CHB-MLI voltage is 0.046%.
