Abstract

Integration of distributed generation (DG) based on the use of new renewable energy is considered to be able to increase the capability of the electric power distribution system. However, the use of inverter-based DG is not optimal, it can worsen the condition of the system, especially in terms of the spread of harmonic distortion which can damage the equipment. This is due to the inverter-based DG technology, apart from supplying electrical energy, DG also injects harmonic currents from existing semiconductor components. This research discusses optimization placement of inverter-based DG using the multi objective particle swarm optimization (MOPSO) method which was tested on the Unit Layanan Pelaksana (ULP) Way Halim 88-bus radial distribution system based on MALTAB 2020b to increase the efficiency of the electrical system by reducing losses and %THDv. The inverter-based DG placed on 24 bus points with a capacity of 690 kW can reduce losses by up to 12.74 kW or 14.96% and all %THDv values for each bus are below 5%.

Abstract

Pada penelitian ini akan dilakukan penentuan setting alat proteksi yang terdapat dalam koordinasi sistem proteksi penyulang Tamarunang dengan adanya pelimpahan beban dari penyulang GHSM. Penelitian ini bertujuan untuk mendapatkan setting koordinasi proteksi pada kondisi pelimpahan beban sesuai dengan standar IEEE 242-2001. Perhitungan setting dilakukan dengan metode diagram impedansi untuk kemudian menghitung arus hubung singkat tiap section. Maka didapatkan setting terbaik OCR PMT Exp GHSM, Basoi dan Mangasa sebagai outgoing masing-masing memiliki nilai TMS = 0,16, relay PMT Exp Malino memiliki nilai TMS = 0,24, pada relay PMT Recloser Rafis memiliki nilai TMS = 0,26, relay PMT Penyulang Tamarunang memiliki nilai TMS 0,35. Pada setting GFR PMT Exp GHSM, Basoi dan Mangasa sebagai outgoing masing-masing memiliki nilai TMS = 0,049, pada relay PMT Exp Malino memiliki nilai TMS = 0,174, pada relay PMT Recloser memiliki nilai TMS = 0,191, pada relay PMT Penyulang Tamarunang memiliki nilai TMS 0,257.

Abstract

Improving power quality in electrical distribution systems is increasingly important with the increasing use of nonlinear loads, such as Adjustable Speed Drive (ASD), which can produce harmonies. This harmonic has the potential to damage equipment, reduce system efficiency, and interfere with power quality. Distribution systems such as IEEE 13 Bus are often used for power quality management analysis. Through simulation, researchers can identify the source and impact of harmonics and evaluate solutions, such as the application of passive filters that absorb or divert harmonic currents, to reduce their negative effects in the distribution system. In this study, two power sources, several transformers, static loads, and nonlinear loads in the form of Adjustable Speed Drive (ASD) were used. The simulation was carried out using Simulink R2019b to model the distribution network, generators, transformers, and loads. The simulation results show that the Adjustable Speed Drive (ASD) load can produce a total harmonic current distortion (THDi) of 24.62% in bus 7, while the total harmonic voltage distortion (THDv) is 0.97%. To minimize harmonic values, passive filters with variations of RL, RC, LC, and RLC are used. The results show that the use of RL passive filters is more effective in reducing THDi and THDv values in bus 7 by 24.47% and 0.97%.
