In high power medium voltage applications, the utilization of 5-H Bridge Multi-Level Inverter (MLI) has grown vastly in recent years. The 5-H Bridge MLI can effectively control link voltage as well as power factor. However, the inverter imparts harmonics owing to the high switching frequency. Hence Inductance Capacitance Inductance (LCL) filter is implemented at its output to mitigate harmonics in presence of non-linear load. It's of highly important to choose LCL parameters wisely in order to attain good filtering effect. This work investigates the application of 5-H Bridge MLI with LCL filter at the output for efficient integration of renewable energy sources on to the grid. A modified fuzzy heuristic approach is used to solve LCL power filter optimization problem at output of 5-H Bridge Multi-Level Inverter. Subject to the constraint's harmonic distortion and losses of the inverter, multi objective optimization problem is solved to obtain LCL filter optimal values. The optimized LCL filter design was applied to a grid connected cascaded H-bridge MLI of rating 4.5 MW, 11 kV. MATLAB-Simulink is utilized for modelling and simulating the system. The results showed that the system is more efficient and generic. dSPACE Hardware in Loop (HIL) test system was used to verify the efficacy of the prototype system.

Penggunaan beban non-linear semakin umum digunakan seiring berkembangnya teknologi yang menerapkan komponen elektronika daya di dalamnya. Beban non-linear dapat menimbulkan harmonisa pada jaringan listrik dan mengakibatkan penurunan kualitas daya. Cara yang dapat digunakan untuk mengatasi permasalahan ini salah satunya adalah dengan menggunakan Active Power Filter. Pada penelitian ini suatu Shunt Active Power Filter (SAPF) untuk sistem satu fasa didesain dan disimulasikan untuk meredam harmonisa yang timbul karena penggunaan beban non-linear satu fasa yang sering digunakan di skala rumah tangga. Teori ip-iq dan kontrol PI untuk tegangan DC digunakan untuk mendapatkan referensi arus kompensasi. Pada simulasi, beban yang digunakan berupa penyearah dioda yang dihubungkan ke beban RL seri. Hasil simulasi menunjukkan bahwa sebelum pemasangan SAPF, nilai THD arus sumber mencapai 32.63%. Sedangkan setelah pemasangan SAPF nilai THD arus sumber yang dihasilkan hanya sebesar 4.47%. SAPF yang disimulasikan memiliki kemampuan peredaman harmonisa sebesar 28.16% dan dapat memenuhi standar yang ditoleransi oleh IEEE 519-2014.

Voltage source inverter (VSI) had been used in dc traction power substation to deliver the trains braking energy back to the utility grid. To mitigate low order harmonics components, pulse-width-modulation (PWM) technique is commonly used in VSI controlled. As a result, the ac voltage and current waveforms may contain high frequency ripples. This paper proposes to mitigate the high frequency harmonics using LCL-filter with series <em>R</em>-damper. This filter offers good attenuation on harmonics with smaller size compare to other passive filter topologies. Theoretical analysis and simulation verification are conducted in designing the proposed filter. System level simulation had also been carried out. Sinusoidal grid current and voltage waveforms are recorded (THD<2%). This paper also includes damping losses analysis in conjunction with resonance peak suppression in designing the <em>R</em>-damper.
