The objective of this work is to construct and assess a variety of machine learning models to forecast the generation of electricity from wind farms using meteorological data, such as wind speed, wind direction, air temperature, humidity, and atmospheric pressure. We tested six models, of which three were based on a recurrent neural network approach. The most pertinent elements for precise predictions were found using feature selection algorithms after preprocessing the meteorological and wind farm power generating data. The results of the study indicate that the best option to predict the generation of electricity from wind farms using meteorological data is the model based on bidirectional LSTM. The study also emphasizes how crucial feature selection and hyperparameter adjustment are for enhancing model performance. Future work may investigate different machine learning models, include more features or data sources, and evaluate how well the models can be used in energy management systems in the real world.","PeriodicalId":149255,"journal":{"name":"2023 IEEE 10th Jubilee Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114490127","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}

A special multi-hop node (MHN) that uses GHz radio waves has been developed for the study. The multi-hop node design is based on Yagi-Uda antennas, a voltage doubler-based RF-DC converter, a two-stage amplifier and a capacitor for energy storage. The experimental study is performed in laboratory conditions emulating a real-life environment with line-of-sight propagation with 27 dBm transmitted power and a 3.8-6.5 m distance range. The experimental setup comprises a transmitter, a multi-hop node, an edge node equipped with a voltage-doubler-based RF-DC converter, as well as measurement equipment. The wireless power transfer efficiency measurements for direct (without the multi-hop node) power transfer scenarios are also performed to evaluate the efficiency of the multi-hop-based WPT. The edge node received averaged power in both cases and RF-DC converted voltage is measured and analyzed.","PeriodicalId":149255,"journal":{"name":"2023 IEEE 10th Jubilee Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116145477","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}

High-order differential pulse position modulation (DPPM), which can be efficiently demodulated using an event timer, presents advantages over other PPM modulation methods because it can provide higher data rates and does not require synchronization. This research aims to demonstrate data transmission using high-order DPPM signal in a laboratory environment and measure bit error ratio (BER) for position widths 50–200 ps. In the theoretical part, an assessment of data transmission rate dependence from the position count and position width of DPPM signal with guard time is presented. Moreover, a theoretical comparison in terms of power efficiency and maximum data rate with other types of PPM, such as transmitted reference pulse-position modulation (TR-PPM), is made. In the experimental part, the performance measurements of DPPM communication system consisting of arbitrary waveform generator (AWG) as DPPM transmitter and Eventech A033-ET/USB event timer as digital-to-time converter (DTC) of DPPM receiver are presented.","PeriodicalId":149255,"journal":{"name":"2023 IEEE 10th Jubilee Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130515955","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}
