Abstract

The increasing penetration Renewable Energy Source (RES) in electrical power grid, the power system must minimize costs and comply with operational and safety requirements. Optimal power flow (OPF) contributes to this objective by determining the optimal control settings, satisfying system and safety constraints, and enhancing operational efficiency. A systematic review was conducted to assess how OPF studies have been evaluated in the literature. The review analyzed 64 journal articles to identify specific OPF studies from three perspectives: type of RES penetration, objective function, and method of OPF. The results indicate that (a) wind turbines are the most commonly used RES model in OPF studies, (b) cost function is the primary objective that the majority of research has considered, and (c) novel meta-heuristics have often been used in OPF methods under uncertain RES penetration. This systematic review identifies research gaps and topics for further research to study OPF with RES penetration. The findings are expected to benefit researchers in deciding the best OPF method under uncertain RES.

Abstract

The thrust roller control and monitoring system is very important in the cement production process, especially in the cement processing process that occurs in the Kiln equipment. At PT. Semen Padang, the thrust roller control and monitoring process using a potentiometer sensor often experiences problems. Based on this, this study aims to develop a solution to the problem of the thrust roller control and monitoring system to make it more accurate. This study was conducted using an experimental method. With this method, the author took some test data on the ultrasonic sensor as a substitute for the potentiometer sensor and then compared the test data with the actual value to determine the level of feasibility and error in the system. The research instrument used in the test was a meter while the object of the study was the thrust roller prototype that had been made. Based on the test results, the thrust roller control and monitoring system has been successfully carried out where the thrust roller movement is displayed in the form of an HMI screen simulation with a small error rate, namely from 20 trials 18 of them were successful while the remaining two experienced errors
