However, considering the unpredictable fluctuations of the DC RPGs and loads, the bus voltage stability of the DCDNs should be given adequate attention. This paper proposes a modified voltage control method for DC distribution networks to address this critical issue by coordinating PV generation, convertor station, and energy storage unit. Firstly, the theoretical model of the medium-low voltage DCDNs is established, and the operating characteristics are analyzed. Then, various control modes based on the voltage deviation level are introduced, and the coordination control philosophy in different operation modes of the DCDNs is stated. Using MATLAB/SIMULINK, a detailed model of ±10 kV/750 V DCDNs simulation model is created, and simulations of different operation modes are performed to check the modified voltage control method’s efficacy. The results illustrate that the proposed control strategy can efficaciously guarantee the power balance, enhance the voltage stability of the DCDNs, and achieve smooth control switching to face various operating conditions. Therefore, the availability and feasibility of the modified voltage control method are demonstrated favorably.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126384450","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 location approach for forced oscillation sources in the time-frequency domain is proposed in this paper, utilizing the short-time fourier transform based synchrosqueezing transform. Firstly, this method applies synchrosqueezing transform to the phasor measurement information, establishes a synchrosqueezing transform coefficient matrix, and determines the frequency band corresponding to the forced oscillation based on relative energy weighting. Then, based on the derived time-frequency domain dissipation energy flow calculation method, the dissipation energy of the frequency band where the forced oscillation occurs is calculated, furthermore, the characteristics of time-frequency domain dissipation energy flow are used to determine the location of the forced oscillation source. The proposed approach’s effectiveness and precision are then validated using simulated data of forced oscillations in the WECC 179 bus power system.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"113 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116119331","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}

It can be obtained from many organic materials and wastes in our daily life. However, the raw biogas cannot be used directly for its low concentration of methane, so an upgrading process and a liquefaction process is need. In this paper, a kind of new system used for biogas liquefied technology was designed. The system consists of screw compressor, water cooler, turbo expander, separator and heat exchanger. Before the biogas enters the system, water scrubbing was carried out to upgrading the biogas. Aspen HYSYS was used for the study to understand the effect of physical parameters such as temperature, pressure and the concentration of the biomethane in the biogas. The results from the simulations show that the energy consumption increased with the increase of the biogas inlet temperature, whereas the liquefaction ratio stay stable. When the inlet gas pressure increased, the energy consumption decreased quickly but the liquefaction is increased. And with the increase of the biogas flow rate, the energy consumption increased and the liquefaction is decreased.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116131360","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}

In this paper, the status of research for wide-frequency oscillation measurement communication transmission is described in detail, and then a transmission method suitable for wide-frequency measurement data is proposed. Firstly, the dual- channel communication of wide-frequency master and substations is adopted to decouple the transmission channel of synchrophasors and wide-frequency data, so as to reduce the transmission rate for synchrophasors. Secondly, wide-frequency data is refreshed at different intervals on the basis of the running status of the power grid, which effectively reduces the real-time data flow between wide-frequency master and substations, reduces the communication burden, and improves the reliability of data transmission. The practicability and effectiveness of the method are verified by simulation in the end.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116665811","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}

In this study, a tower displacement monitoring scheme combining finite element method (FEM) and deep learning (DL) was developed. The response data of wind-induced transmission tower vibration under different fault conditions were simulated by FEM. The tower fault database is expanded by means of data enhancement.

The objective of this research is to develop algorithms and techniques for monitoring the state of power distribution networks, identifying any abnormal conditions, and taking appropriate actions to ensure the reliability and stability of the network. Intelligent monitoring involves the use of advanced sensors, communication networks, and data analytics tools to continuously monitor the key parameters of the power distribution network. These monitoring parameters include voltage, current, power flow, partial discharge, mechanical vibration, overheating temperature and other electrical quantities. The edge computing technique in electrical power equipment condition monitoring will be real-time, intelligent, but also has good data processing ability for intelligent monitoring of power distribution network. The data from these sensors is collected and analyzed by edge computing in real-time to detect any abnormalities or deviations from the normal operating conditions. Multi-parameter identification involves the use of advanced data analytics tools to identify the relationships between different parameters of the power distribution network. This enables the identification of any inter-dependencies or correlations between different parameters, which can be used to identify the root cause of any abnormalities in the network. The use of intelligent monitoring and multi-parameter identification can help power distribution companies to improve the reliability and stability of their networks, reduce downtime, and optimize their operations. It can also help to improve the quality of service provided to customers by ensuring that power is supplied reliably and consistently in new power system.","PeriodicalId":403002,"journal":{"name":"2023 8th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133349312","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}
