Abstract
Sistem turbin angin sangat dipengaruhi oleh kondisi angin yang fluktuatif, sehingga menyebabkan daya keluaran pada sistem turbin angin pun juga mengalami fluktuasi dan daya pada DC Bus tidak akan konstan. Oleh karena itu, pada sistem turbin angin membutuhkan baterai sebagai penyimpan energi. Ketika daya keluaran pada sistem turbin angin dengan generator PMSG melebihi kebutuhan daya beban maka daya akan disimpan ke dalam baterai (mode pengisian). Begitu juga sebaliknya, ketika daya yang dibangkitkan sistem turbin angin-PMSG tidak mampu memenuhi kebutuhan beban maka baterai akan membantu menyuplai daya yang dibutuhkan (mode pengosongan). Operasi pengisian dan pengosongan baterai diatur dengan menggunakan konverter bidirectional. Konverter DC-DC bidirectional dapat bekerja dalam dua mode, yaitu mode pengisian baterai (mode buck) dan mode pengosongan baterai (mode boost). Metode pencarian daya maksimal dengan menggunakan metode berbasis Modified Perturbation and Observation (P&O) juga digunakan untuk mengatur pensaklaran pada konverter boost sehingga didapatkan Maximum Power Point (MPP) dari sistem turbin angin. Hasil dari penelitian ini mampu mempercepat kondisi tunak pencarian daya maksimal jika dibandingkan dengan metode P&O konvensional. Serta konverter bidirectional mampu mengatur proses pengisian dan pengosongan baterai dengan baik.
============================================================
Wind turbine system is influenced by wind conditions changing, causing the output power at the wind turbine system also fluctuated and power on the DC bus will not be constant. Therefore, the wind turbine system on a stand-alone condition requires a battery as energy storage. When the output power of Permanent Magnet Synchronous Generator (PMSG) on wind turbine system is greater than the required power load, it will be stored in the battery (charging mode). Likewise, when the power generated PMSG not able to serve the power requirements of the load, the battery will also supply the required power (discharge mode). Battery charge and discharge operation is set by using a converter. Bidirectional DC-DC converter can work in two modes, namely battery charging mode (buck mode) and a battery discharge mode (boost mode). Maximum power tracking method based on Modified Perturbation and Observation (P&O) is also used to set the switching boost converter to obtain the Maximum Power Point (MPP) of a wind turbine system. The results of this study could accelerate the steady conditions in the maximum power tracking compared to the conventional P&O method and bidirectional converter is able to regulate the process of charging and discharging the battery properly.
