Abstract
Pada sistem generator turbin angin, daya yang dihasilkan bergantung kepada kecepatan angin yang menggerakkan turbin. Salah satu metode yang bisa digunakan untuk mengatasi fluktuasi kecepatan angin adalah dengan memanfaatkan energy storage system (ESS) terutama battery energy storage sytem (BESS). Batas arus dan tegangan pengisian baterai yang tidak dikontrol dapat menyebabkan kerusakan pada baterai. Pada penelitian ini, membangun battery energy storage system (BESS) menggunakan boost converter dengan controller PI dengan besar gain Kp yaitu 150 dan Ki sebesar 22,653, kemudian membuat sistem proteksi yang terdiri dari relay untuk menghindari overcharging. ∆V antara nilai kecepatan angin dengan pemberian setpoint akan mempengaruhi kinerja sistem. Semakin kecil ∆V yang terjadi atau jauh penyimpangannya dari ∆V desain, maka ripple tegangan output akan besar. Sumber generator turbin angin dengan pemberian beban 12 Ω menarik arus 180 mA dengan tegangan output sekitar 4 volt, beban motor dc menarik arus hingga 70 mA dengan tegangan 9 volt, dan arus pengisian baterai sekitar 40 mA dan tegangan pengisian diantara 12,8 volt hingga 13,43 volt dengan kecepatan angin 7 m/s. Rangkaian proteksi berfungsi dengan memberikan logika high pada saat kondisi maksimum tegangan baterai 13,65 volt untuk menghindari overcharging.

In a wind turbine generator system, the power generated depends on the wind speed that drives the turbine. One of method that can be used to overcome wind speed fluctuations is to utilize energy storage systems (ESS), especially battery energy storage system (BESS).Uncontrolled current and battery charging limits can cause damage to the battery. In this study, building a battery energy storage system (BESS) uses a boost converter with a PI controller with a gain of Kp is 150 and Ki is 22,653, then makes a protection system consisting of relays to avoid overcharging. The ∆V between the value of wind speed and giving a setpoint will affect system performance. The smaller the ∆V occurs or the deviation is far from ∆V design, then the output voltage ripple will be large. The source of a wind turbine generator with a load of 12 Ω draws a current of 180 mA with an output voltage of about 4 volts, dc motor load draws currents up to 70 mA with a voltage of 9 volts, and the battery charging current is around 40 mA and the charging voltage is between 12,8 volts to 13,43 volts with a wind speed of 7 m / s. The protection circuit functions by providing high logic when the maximum battery voltage is 13,65 volts to avoid overcharging.
