Abstract

Kinerja sistem mikro grid dalam pengaturan untuk mengendalikan aliran daya secara terpisah ke DC bus dengan sistem terpusat cukup baik, karena sumber DC dari PV cukup untuk memenuhi permintaan beban dan untuk mengisi baterai. Node A dan C menyalurkan daya 1904 watt, daya baterai sebesar 784 watt, dan beban 730 watt. Selanjutnya Pengaturan tegangan DC bus dapat dilakukan dengan sistem hybrid dengan grid AC (sumber penyearah), metode selanjutnya dengan sistem dua PV array dengan baterai, metode sistem hybrid dengan grid AC, sumber AC digunakan untuk pengisian baterai pada sisi grid AC dan metode berikutnya, memperbaiki kinerja MPPT. Dengan menggunakan kontrol fuzzy-PID Pada MPPT dihasilkan tegangan keluaran konverter 24.01 V, sedangkan dengan kontrol PID dihasilkan tegangan keluaran 22.25 V. Kontrol PID menghasilkan overshoot sebesar 1.98 persen dengan rise time 0.139 detik, sedangkan kontrol fuzzy-PID menghasilkan overshoot 1 persen dengan rise time 0.025 detik. Selain itu pengaturan pembagian beban pada DC mikro grid dengan beberapa sumber dan perbedaan tegangan pada DC-DC konverter yang terhubung secara paralel akan mempengaruhi pembagian arus beban. Ketika koefisien droop berbeda, maka terjadi perbedaan arus 0.69 A. Deviasi tegangan pada saat koefisien droop tidak sama dari sumber 1 dan sumber 2 adalah 2.79% dan 2.29%. Untuk meningkatkan kinerja mikro grid digunakan kontrol koordinasi dengan logika fuzzy pada BESS (sistem penyimpanan energi baterai) Hasil penelitian menunjukkan bahwa kontrol logika fuzzy (FLC) memperlihatkan kinerja dengan undershoot 2.32 % dan rise time 3.24 ms, lebih rendah jika dibandingkan dengan kontrol PI.

The performance of the micro grid system in the setting to control the flow of power separately to the DC bus with a centralized system is quite good, because the DC source from the PV is sufficient to meet the load demand and to charge the battery. Nodes A and C deliver 1904 watts of power, 784 watts of battery power, and 730 watts of load. Furthermore, DC bus voltage regulation can be done with a hybrid system with an AC grid (rectifier source), the next method is a two PV array system with a battery, a hybrid system method with an AC grid, an AC source is used to charge the battery on the AC grid side and the next method, improves MPPT performance. By using fuzzy-PID control, MPPT produces a converter output voltage of 24.01 V, while with PID control produces an output voltage of 22.25 V. PID control produces an overshoot of 1.98 percent with a rise time of 0.139 seconds, while the fuzzy-PID control produces an overshoot of 1 percent with a rise time 0.025 seconds. In addition, the load sharing settings on the DC micro grid with multiple sources and the voltage difference on the DC-DC converter connected in parallel will affect the load current sharing. When the droop coefficient is different, there is a current difference of 0.69 A. The voltage deviation when the droop coefficient is not the same from source 1 and source 2 is 2.79% and 2.29%. To improve the performance of the micro grid, coordination control with fuzzy logic was used on BESS (battery energy storage system). The results showed that fuzzy logic control (FLC) showed performance with an undershoot of 2.32% and a rise time of 3.24 ms, lower than the PI control.
