This paper proposes multi-battery design of battery management control using bus communication method based on loop shaping. The experiment of proposed method shows that the capacity dynamics of battery has been improved. The multiple of battery control system is implemented in electric vehicle's model, and we modify the origin control system using bus communication method auto tuning based on loop shaping. The result of modified control system using bus method based on loop shaping is shown in the implementation design response of battery management that the cost and reliability are improved. Moreover, this method could maintain the error steady state to be zero.
Abstract-Renewable energy source likes solar panel and wind turbine have intermittent character from instability power source generated. The instability power source can make dip voltage in power grid which happen in half cycle until few seconds. To stabilize the voltage in power grid from dip voltage, some methods have been developed using power electronics technology like VSI inverter, STATCOM, energy storage, OLTC, and MERS. The power electronic circuits have some advantages, such as small dimensional size and lightweight to keep voltage in power grid. In this paper, the MERS circuit was applied in induction motor which has small full bridge circuit, uncomplexity computation, and low switching frequency, so it needs low end hardware requirement. This paper proposed the use of MERS dc capacitor with 50% value from induction motor resistance. The result shows that MERS has advantage and can keep the voltage in power grid when the voltage below 39% and 15% above rated voltage (220 V rms ) with the recovery time around 0.3 second and keep the dip voltage over 1 second.Intisari-Sumber energi terbarukan berupa panel surya dan turbin angin bersifat intermitten dikarenakan ketidakstabilan daya yang dihasilkan. Ketidakstabilan daya menyebabkan terjadinya dip voltage pada tegangan jaringan, baik dalam beberapa siklus gelombang maupun sampai beberapa detik. Untuk menjaga kestabilan tegangan pada jaringan dari dip voltage, beberapa metode telah dikembangkan dengan menggunakan teknologi elektronika daya, seperti inverter VSI, STATCOM, energy storage, OLTC, dan rangkaian MERS. Rangkaian elektronika daya mempunyai keuntungan berupa dimensi rangkaian yang kecil dan kompak untuk menjaga tegangan jaringan. Pada makalah ini, rangkaian MERS diaplikasikan pada motor induksi karena kesederhanaan rangkaian yang berbentuk full-bridge, komputasi yang tidak kompleks, dan penyakelaran frekuensi rendah sehingga tidak membutuhkan perancangan perangkat keras high end. Makalah ini mengajukan perhitungan nilai kapasitor dc pada rangkaian MERS dengan nilai 50% dari hambatan total motor induksi. Hasil simulasi menunjukkan bahwa MERS mempunyai kelebihan dan dapat menjaga tegangan jaringan saat tegangan lebih rendah dari 220 Vrms sampai 39% dan saat tegangan lebih tinggi dari 220 Vrms sampai 15%. Waktu perbaikan yang diperlukan adalah sekitar 0,3 detik dan tegangan dapat terjaga dari dip voltage lebih dari 1 detik.Kata Kunci-dip voltage; intermitten renewable energy sources, induction motor, MERS.
