When the magnet moves in the coil or vice versa. The rotation of the machine will change the flux of magnetic force on the coil and penetrate perpendicularly to the coil so that a potential difference arises between the ends of the coil. It is caused by a change in magnetic flux. The Firefly Algorithm (FA) method has been proven successful in overcoming system optimization problems. Modifying the FA is expected to improve its performance of the FA. To get the best control method, it is necessary to vary the speed control model. This study compares the PMSM speed control without a controller, PID Control, PID-FA, and PID-FA-ANFIS. The simulation results show that the best model on the PID-FA-ANFIS controller which is closest to the Speed Reff (2980 rpm) is that PID-FA-ANFIS obtains a rotation profile with the smallest undershot, the fastest steady state, the best output current profile, the best torque profile, and the best stress profile. The results of this study will be followed by other uses of artificial intelligence.     ","PeriodicalId":285860,"journal":{"name":"Frontier Energy System and Power Engineering","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114854867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrical power produced by the Permanent Magnet Synchronous Generator at Wind Power Plants in Indonesia is influenced by low wind conditions with wind speeds only ranging from 2.5 to 6 m/s. So that the output voltage can produce optimal power with a low and fluctuating average wind speed, an optimization will be carried out using the Gray Wolf Optimization method which is inspired by the social strata of wolves in hunting their prey. This method works by measuring the voltage and current at the load to get optimal power and maximize the existing power extraction using Maximum Power Point Tracking.    ","PeriodicalId":285860,"journal":{"name":"Frontier Energy System and Power Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125811926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the increasing amount of production, the amount of load will increase so that additional generator capacity is required. This research aims to determine the analysis of power flow planning and coordination setting system protection against the addition of 30 MW generator capacity. Analyze the power flow using ETAP software with the Adaptive Newton-Rapson method. The results of the study showed after the 30 MW generator was added, the work percentage of generators 1 and 2 was lighter and the value of the power flow is relatively the same if the load value is unchanged.

Solar energy produced by panels on the roof can be used as a source of power. Semiconductor-based solar panel technology can absorb photons from sunshine and transform them into ecologically beneficial electrical energy. Of course, a control device that regulates the electrical energy charging system is required when using solar cells as a power source to charge a battery. This device is typically referred to as a charge controller. The DC-DC converter of the buck type with a Ziegler Nichols-based Proportional Integral Differential (PID) control approach utilizing Arduino Uno is the control system utilized in this solar cell battery charging. The buck converter reduces and stabilizes the solar panel's output voltage following the requirements for charging the accumulator. For charging batteries, a set point voltage of 13.8 V is employed. By testing the converter with both static and dynamic loads, the research that has been done can produce results. The 35 Watt lamp static load test results with a fixed voltage source show that the set point voltage is 13 V and that it takes 28 s to attain a steady condition. When applied to dynamic loading using a battery charge of 12 V/7.5 Ah with a 20 WP solar panel source during hot, partly cloudy weather, the charging efficiency is 68 percent. A steady state of about 28 s may be claimed to be a satisfactory control system response.","PeriodicalId":285860,"journal":{"name":"Frontier Energy System and Power Engineering","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114752052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The location of the work is the building of the car dealership. The several works are carried out to measure, calculate and analyse data to get Energy Consumption Intensity or ECI of the building. In the next step of the research, preliminary calculations and analyse are used to look for technical improvement steps to increase the low Energy Consumption Intensity value in certain rooms. The technical improvement steps are then reviewed to obtain the necessary recommendations to achieve a specific efficiency score. The electricity efficiency audited according to the standard is 2,698.65 kWh/ month. High-purity hydrocarbon refrigerant is suggested to use directly to replace synthetic refrigerants in chillers. This refrigerant has various advantages including 20% energy saving, no ozone causing damage and greenhouse gas effects. Lighting software is used to simulate the number of light points. The advantage of this software is that it not only focuses on the engineering side, but also in terms of visualization.
