However, the conversion of solar/wind energy is highly dependent on the availability of sunlight and wind speed. Therefore, it is necessary to study the PV /wind loading which aims to increase and maintain the continuity of the electricity supply to the load. Load power management follows the availability of solar and wind energy in sunny, cloudy, rainy, or evening weather by considering the remaining usable battery voltage. Comparison of data is done to determine the system constraints with the ANFIS method. In testing the data with ANFIS performed with 3 MF (High, Medium, Low). From a total of 4003 data and an error of 26% was found, the training data was then compared with the test data. After testing the data comparison between the actual data and the training data that has been processed with ANFIS, it is obtained that there are more options for the maximum load that can be supplied by PV /wind generation. This has an impact on the performance of the hybrid PV /wind standalone which is more leverage on the loading side.","PeriodicalId":259450,"journal":{"name":"2021 8th International Conference on Electrical Engineering, Computer Science and Informatics (EECSI)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128697706","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}

To avoid the potential accident, information about the potential of LLWS occurrence ahead was needed so the pilot can avoid the area where LLWS can happen. Previous several studies used statistical model to predict LLWS. The dataset comes from the equipment system for detecting LLWS. Most of the statistical models used are Multi-Layer Perceptron (MLP) and the dataset is taken from Lidar Doppler. The approach that is often used is to transform wind data from Lidar Doppler into time series data and feed it to the MLP. For this study, the statistical model used is Temporal Convolutional Network (TCN). TCN is a dedicated time-series model. The dataset for the TCN is come from Low-level Wind Shear Alert System (LLWAS). We use the model to predict LLWS occurrence 5 minutes ahead. The feature input of TCN are wind direction and speed from LLWAS that already is being transformed and arranged to timeseries data west - east component (U) and south - north component (V). The label dataset is LLWAS's warning of LLWS occurrence data. As a comparison of the proposed model, a logistic regression model and Multi-Layer Perceptron (MLP) were also used. We also use varying lengths of input data to see how they perform against the model. The results show that TCN can outperform other comparison models with perfect recall and precision values (1) when using predictor time-series data longer than 5 minutes. This result means that the proposed model works well in predicting LLWS events using LLWAS data.","PeriodicalId":259450,"journal":{"name":"2021 8th International Conference on Electrical Engineering, Computer Science and Informatics (EECSI)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126995642","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 objects were limited to humans, motorcycles, and cars. The results showed that the most compatible YOLO model for the system was the Tiny YOLOv4 model which was built with the darknet framework. The simulation experiment showed that detection accuracy was 80% and was able to transmit information in a form of data location of the object to the microcontroller. A success rate of 100% was obtained from 10 tests. Hence, it showed that the YOLO was able to detect objects and provided input to the steering control system. Meanwhile, the depth information method was used to measure the distance of the object to the vehicle in real-time with an accuracy of 60%. Real-time testing was conducted to test whether the autonomous electric vehicle can avoid objects in front of it by providing input from the detection results of the Tiny- YOLOv4 model object.

The AC-DC-AC converter consists of a Generator Side Converter (GSC) and a Load Side Converter (LSC) which are installed back to back via the DC-Link network. The effectiveness and dynamic characteristics of the controller design were evaluated and analyzed through simulation using the PSCAD program. Simulation analysis is divided into 2 fault scenarios, namely: (1) Analysis of small disturbances in the form of changes in load and generator rotation differences, and (2) Analysis of large disturbances due to short circuits in the transmission network.

This line is covered by polyamide Stany 1 material that is very sensitive to the temperature. The spiral resonator has resonance frequency $f_{i}$ (logic 1 state) and can be disconnected near the intersection with the extra arm to shift its resonance frequency beyond the tag operation (logic 0 state).
