Energy routers (ER) are the key equipment of the energy internet that provides control over bidirectional power flows and the voltage level of an electric network. The paper presents the thyristor-powered ER (TER) for an Internet-style medium voltage distribution electric network (6, 10, 20 kV). The developed scheme of the device implements longitudinal and transverse voltage regulation at the ER connection point and it allows changing the power flow and the voltage level in the network. The article is devoted to the study of the harmonic components of voltage introduced into the electrical network by the semiconductor elements of the TER. A mathematical and a computer model and a prototype of an electric network section with a TER have been developed. The studies carried out with the help of the developed models have shown that the device does not significantly distort sinusoidally. The harmonic components factor of the output voltage has acceptable values over the entire range of an effective regulation.

The rising electricity consumption, rapid fossil fuel depletion, and a higher shift to the use of renewable or green energy resources have increased the need to integrate renewable and distributed energy resources (DERs), like solar photovoltaic (PV) energy to power the utility grids. In this study, the researchers have determined the effect of PV inverters to offer reactive power to an adapted IEEE 13-node distribution network. Power flow analyses were conducted on MATLAB/Simulink for various reactive power modes of PV inverters to show the effect of the reactive power on the regulation of grid voltage, reduced the total harmonic distortion (THD), and maintain the power factor so as to improve the ability of the system to handle power. The result shows that using a 400 KW PV system in a bus (675) led to a reduction in the power generated from the generator by 11%, and the use of the reactive power capability of PV inverters on-site improved the voltage profile significantly. as well, reduced the voltage THD by 27.09% when injected with reactive power, reduce the current THD by 77.39% When absorbing reactive power, and improved the power factor on-site.

Tujuan penelitian ini mengetahui pengaruh penambahan kapasitor bank terhadap Perbaikan Daya pada Direct On Line (DOL) berbasis Programmable Logic Controller (PLC) di Motor Listrik 3 Phase. Mayoritas beban di industri memakai beban motor induksi 3 phase yang merupakan beban induktif. Keuntungan motor listrik 3 phase tersebut dan negara yang masih menyubsidi konsumsi listrik. Hal ini merupakan suatu indikasi setiap konsumen dapat melakukan perbaikan faktor daya dengan tujuan efisiensi daya. Penelitian yang digunakan adalah jenis kuantitatif dengan mengeksperimenkan penambahan kapasitor bank pada motor 3 phase. Melalui tahapan perancangan alat, pengujian alat pengambilan data faktor daya & efisiensi, analisis data dan penarikan kesimpulan. Hasil penelitian penggunaan kapasitor bank berpengaruh pada perbaikan faktor daya yang ditunjukkan dari signifikasni 0,001 < 0,05 pada rangkaian DOL di motor listrik 3 fasa berbasis PLC. Diperkuat dengan nilai rata-rata cos phi sesudah penggunaan kapasitor bank memiliki nilai 0,912 yang artinya sudah sesuai standar PLN yaitu nilai 0,9. Cos phi mendekati angka 1 dapat dikatakan penggunaan listrik lebih efisien. Dapat dilihat dari nilai rata-rata efisiensi sebelum dan sesudah yaitu 68,29% menjadi 91,17% artinya mengalami peningkatan.
