Renewable energy sources require an energy storage system because its are fluctuating and electricity producing at certain times, even sometimes not in accordance with the needs of the load. To maintain continuity of electricity, smart battery energy storage system is needed. Therefore, this paper of a full-bridge bidirectional DC-DC Converter (FB-BDC) with Fuzzy Logic Control (FLC) is designed and implemented for battery energy storage application. The FLC has error and delta error of voltage level as input and duty cycle of FB-BDC as output. The FB-BDC is controlled by a microcontroller ARM Cortex-M4F STM32F407VG for voltage mode control. The FB-BDC topology is selected becuase battery storage system needed isolated and need high voltage ratio both for step-up and step-down. The main purpose of FB-BDC to perform bidirectional energy transfer both of DC-Bus and battery. Moreover, FB-BDC controls the DC-Bus voltage according to referenced value. The power flow and voltage on DC-Bus is controlled by FLC with voltage mode control. The experiment result shows the ability of FLC voltage mode control to control FB-BDC on regulate charging voltage with an error 1% and sharing voltage 1.5% form referenced value.

This paper proposes method of series DC arc fault protection using low cost microcontroller. Series DC arc fault occurs when gap between conductor or wire flows a current. Series DC arc fault can cause fire hazard if do not detected and protected. However, Series DC arc fault is difficult to detected using conventional protection. To detect series DC arc fault accurately using fast Fourier transform (FFT). FFT is used to transform signal in time domain to frequency domain. Series DC arc fault has different characteristic compared by normal current in frequency domain. Therefore, the proposed algorithm for protection of series DC arc fault based on magnitudes of the current in frequency domain. Hardware system is implemented by 100 V DC power supply and DC arc fault generator. Test result is conducted experimentally under varying of load current such as 2 A, 2.5 A, 3 A, 3.5 A, 4 A and 5 A. Experimental testing results show that Series DC arc fault protection has time for trip of 0.48 s, 0.26 s, 1.04 s, 0.68 s, 0.44 s and 0.48, respectively. The fastest time for trip is 0.26 s with current of 2.5 A. Therefore, the proposed algorithm for series DC arc fault protection can operate to trip accurately and have the good performance.

Photovoltaic (PV) is a renewable electric energy generator that utilizes solar energy. PV is very suitable to be developed in Surabaya, Indonesia. Because Indonesia is located around the equator which has 2 seasons, namely the rainy season and the dry season. The dry season in Indonesia occurs in April to September. The power generated by PV is highly dependent on temperature and solar radiation. Therefore, accurate forecasting of short-term PV power is important for system reliability and large-scale PV development to overcome the power generated by intermittent PV. This paper proposes the Jordan recurrent neural network (JRNN) to predict short-term PV power based on temperature and solar radiation. JRNN is the development of artificial neural networks (ANN) that have feedback at each output of each layer. The samples of temperature and solar radiation were obtained from April until September in Surabaya. From the results of the training simulation, the mean square error (MSE) and mean absolute percentage error (MAPE) values were obtained at 1.3311 and 34.8820, respectively. The results of testing simulation, MSE and MAPE values were obtained at 0.9858 and 1.3311, with a time of 4.591204. The forecasting has minimized significant errors and short processing times.

Series Arc Fault is one of the disturbances of arcing jump is caused by gas ionization between two ends of damaged conductors or broken wire forming a gap in the insulator. Series arc fault is the primary driver of electrical fire. However, lack of knowledge of the disturbance of series arc fault causes the problem of electrical fire not be mitigated. Magnitude current is not capable to detect of series arc fault. Therefore, this paper proposes fast fourier transform (FFT) to detect series AC arc fault in low voltage using microcontroller ARM STM32F7NGH in real time. A cheap and high speed of microcontroller ARM STM32F7NGH can be used for FFT computation to transform signal in time domain to frequency domain. Moreover, in this paper, protection of series AC arc fault is proposed in the real time mode. In this experimental process, some various experiments are tested to evaluate the reliability of FFT and protection with various load starts from 1 A, 2 A, 3 A, 4 A in resistive load. The result of this experiment shows that series AC arc fault protection with STM32F7 microcontroller and FFT algorithm can be utilized to ensure series AC arc fault properly.

Arc merupakan loncatan bunga api yang disebabkan karena adanya pelepasan energi dari kabel penghantar. Arc fault menghasilkan panas yang dapat merusak isolasi kawat sehingga dapat menyebabkan terjadinya bahaya kebakaran. Namun keterbatasan akan hal memonitoring seluruh jalur pengawatan menjadi kendala dalam pendeteksian secara dini adanya gangguan arcing. Dirancang sebuah alat identifikasi arc fault pada kabel berjenis serabut dan pejal, yang mana dapat mencegah kebakaran dikarenakan keterlambatan untuk mengamankan bahaya arcing. Pada alat ini memanfaatkan AMC1301 sebagai sensor tegangan dan sensor arus. Sistem ini bekerja mengamankan instalasi saat terjadi gangguan serta dapat mengirim kondisi secara real status dari jalur pengawatan (ada gangguan arc atau tidak). Kondisi dari sistem instalasi yang terbaca oleh sensor diolah oleh mikrokontroler dan metode yang digunakan adalah mendeteksi munculnya komponen frekuensi tinggi pada arus sistem menggunakan Fast Fourier Transform (FFT). Apabila mendeteksi adanya gangguan busur seri AC, maka mikrokontroler akan mengolah data dengan FFT dan diidentifikasi jenis kabel uji sesuai karakteristiknya ketika terjadi gangguan. Penelitian ini dibangun pada sistem tegangan rendah 220V/50Hz dengan arus gangguan sebesar 0,83A dengan beban resistif. Data pengujian menunjukkan bahwa AFCI dengan metode FFT mampu mendeteksi gangguan busur seri AC dan memberikan proteksi pada sistem dengan rata-rata waktu pemutusan 872 ms.

In recent years there is an increasing demand for closely regulated dc power supply. Most of the power electronic converters in these power supplies used full wave rectifier. Bulky filter capacitor in rectifier can effect non-sinusoidal input current waveform (distorted). The difference in voltage and current waveform affected the power factor system. Interleaved Boost Converter (IBC) as Power Factor Correction (PFC) with a fuzzy logic controller to be added in the system to achieved near to unity power factor. IBC operated in Discontinuous Conduction Mode (DCM). Power factor near to unity can be achieved while rectifier supplied resistive load, the waveform of load current through back to input source have the same form with the input voltage. Simulation and hardware implementation is used by varying loads. The experimental results with a variable load value of IBC as PFC can improve the power factor system from 0.67 to 0.93.
