A novel DC arc fault detection method using Pseudo Wigner-Ville distributed (PWVD) algorithm is proposed. Arc fault experiment platform in a 5 kW grid connected PV system is built, and the circuit current of the PV strings under different test conditions are measured. The PWVD algorithm is used to analyze the currents. The time frequency graph of the current can be obtained, and the characteristic parameters for arc fault detection are extracted. The PWVD results can intuitively reflect the time, frequency and amplitude information of the current. The proposed method can detect DC arc fault in PV system accurately.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123418527","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 recent years, the deep learning method has been widely used in non-intrusive load dis-aggregation, but most of the current research only use low frequency active power signal for power disaggregation and does not consider the correlation of load power consumption patterns, which leads to load dis-aggregation can not achieve the desired effect. This paper presents a non-intrusive load disaggregation method based on deep learning and multi-feature fusion. In addition to the electric information of the load, the water and gas information of the load are also considered, and the correlation between the appliances power consumption patterns is studied.

This paper points out that it is not necessary for a voltage source converter (VSC) to operate exactly as an SG. Instead, the merits of VSCs should be better utilized to solve SGs’ drawbacks. Considering VSCs’ flexibility in active power control, this paper utilizes the energy function approach of Lyapunov’s second method in VSG design. In addition to the basic differential and algebraic equations of conventional VSGs, this paper introduces a difference equation to modify the virtual frequency of VSGs. The modified VSG successfully mitigates power angle oscillation and improves transient stability in a way that SGs and conventional VSGs can hardly do. Related RTDS simulations are also demonstrated in the paper.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126434570","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}

Our algorithm is practical for threading engineering. The wire image can be processed only by using a portable computer. The processing time of each frame is less than 200ms, and the recognition accuracy has reached the level of state-of-the-art.
