Abstract

A microgrid usually consists of small-scale of thermal generation sources and other distributed energy resources (DER) such as photovoltaic, wind power, and fuel cells to serve its loads. In this paper microgirid AC system using wind turbines. Microgrid AC systems use an inverter which is a source of harmonics for need to convert to AC system Load . And the system will also get the source of harmonics when the system is connected to the non-linear load. wind turbines can generate harmonics also. So that it can degrade the quality of the power of the system. In addition the power factor, and voltage system is not good. So thesystem mitigate solution is using a passive filter tuned to the affected bus. The simulation results show that the design singgle tune passive filters can be effective and have a good performance in mitigating microgrid system

Abstract

From the research that has been done at the Blitar Square Shopping Center, it was found that the power factor value is still below the standard with an average value of 0.711. Therefore, it is necessary to improve the power factor by installing a capacitor bank. The calculation results show that global compensation requires 12 capacitor banks with a rating of 10.4 kVAR, while sectoral compensation on the chiller load panel requires 7 capacitor banks with a rating of 10.4 kVAR and the foodmart load panel requires a capacitor bank with a rating of 10. 4 kVAR is 6 pieces. In addition, the installation of a capacitor bank also results in an increase in the voltage value in the system, this voltage increase is still below the permissible standard of ± 5%. The simulation of installing a capacitor bank on global compensation can improve the power factor value from 72.99% to 96.97%, with a voltage increase of 0.479% from the initial value of 397 V to 398.9 V, and a decrease in the current value of 24.645% from the initial value. 330.7 A to 249.2 A. While the simulation of installing a capacitor bank in sectoral compensation can improve the power factor value from 72.99% to 93.57%, with a voltage increase of 0.401% from the initial value of 397 V to 398.6 V , and a decrease in the value of current by 21.593% from the initial value of 330.7 A to 258.1 A.

Abstract

In an increasingly advanced era, electrical energy has become a basic resource for humans, the wider and more equitable distribution has greatly influenced the progress of all sectors of electricity users. However, on the other hand, this hydroponic business requires precision and special attention by the actors to support the maximum success of the hydroponic business. Several previous tools have been able to overcome the problem of irrigation for hydroponic plants. However, there is no tool that can regulate the addition of nutrients based on the internet of things and monitor the hydroponics. So, a tool for adding nutrients to hydroponic plants based on the internet of things was designed that is equipped with supervision on plant nutrition. It is hoped that after the manufacture and analysis of tools on hydroponic plants can overcome the problems that are often experienced by hydroponic entrepreneurs.The research was conducted from May to July 2022 in Margoutomo Dalam, Dau, Malang. This nutrient addition tool is designed using an Arduino Uno microcontroller where as a regulator and NodeMCU is added as an online access on the user's cellphone. After the tool has been designed, a regression analysis is carried out to determine the effect of nutrient levels on the fertility of hydroponic plants. The results of this study showed that the nutritional value of a good plant was 350 ppm, with the response rate of this nutrition enhancer at 1.62% per second at a distance of 338 km for testing the user.
