Solar energy is one such RES that is gaining popularity for its availability throughout the day at different intensities and vast potentiality in the processes aiding grid integrations. The features of Photovoltaic (PV) cells mainly rely on climatic conditions like temperature, irradiance that are prone to fluctuations. In addition to this, the unpredictable nature of PV systems necessitates a requirement to assess and test the data corresponding to solar energy using appropriate Maximum Power Point Tracking (MPPT) techniques. This paper focuses on the mechanism of Perturb and Observe (PO) algorithm, a highly efficient MPPT technique implemented on a Solar PV array coupled with a boost converter on MATLAB/SIMULINK with the aim of improving the overall optimality of the solar power data as well as the system on which it is used and also includes a brief comparison of the employed method with other widely used MPPT techniques.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116805498","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}

However, traditional reliability assessment in distribution system is usually conducted from system side, while neglecting the negative impact on reliability level from power quality problems, such as voltage deviation (usually low voltage problem) and voltage sags. To overcome the shortcomings mentioned above, some new metrics for distribution reliability assessment considering the influence from power quality problems are presented in this paper. Those metrics considering influence from low voltage problem and voltage sags, can be defined as “equivalent reliability metrics”. In addition, a modified reliability assessment method for distribution system considering power quality problems is proposed in this paper, in order to calculated the proposed new metrics considering power quality from consumer-side. A case study is applied to illustrate the effectiveness and efficiency of the proposed metrics and method.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128261357","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 long-term working insulation performance of C<inf>4</inf>F<inf>7</inf>N, especially the surface insulation, still needs more research. In this paper, two types of spacers are used to study the surface flashover characteristics in C<inf>4</inf>F<inf>7</inf>N/CO<inf>2</inf> mixture. It is found that the flashover voltage of the plate spacer in 10% C<inf>4</inf>F<inf>7</inf>N /90%CO<inf>2</inf> mixture is lower than SF<inf>6</inf>. When the C<inf>4</inf>F<inf>7</inf>N content increases from 5% to 20%, the surface flashover voltage of the downsized GIL basin spacer increases and C<inf>4</inf>F<inf>7</inf>N/CO<inf>2</inf> mixture has obvious synergistic and polar effect. If the voltage is applied for ten minutes in advance, the homo-charges increase the surface flashover voltage, while the hetero-charges reduce the surface flashover voltage to a certain extent.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133628648","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 the actual calculation process, the accurate calculation of the actual line loss is often difficult to achieve. One of the main problems are due to various reasons, the original data will inevitably accrue data loss and data confusion. To improve the calculation accuracy of the line loss rate, the paper proposes an abnormal line loss data detection and correction method. Aiming at the problem of abnormal power grid data collection, the paper first extracts abnormal power consumption data from historical data, uses AP clustering algorithm to classify abnormal data, extracts the abnormal power consumption behavior characteristics for each type of historical abnormal power consumption curve, and then compares real-time power consumption data with abnormal electricity behavior features, and determines whether abnormal data do occur according to the similarity theory. Finally, DNN algorithm is used to replace the abnormal data. Based on the model proposed, calculations show that the use of the DNN algorithm for data correction not only has a higher accuracy rate but also can better improve the accuracy of the calculation of the line loss rate of the distribution network compared to BP prediction and other regression algorithms.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124809174","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 proposes a new method of vulnerability communication link assessment for electric cyber physical system. Wind power output, transmission line failure and communication link failure of electric cyber physical system are sampled to obtain different operating states of electric cyber physical system. The connectivity of communication links under different operating states of electric cyber physical system is calculated to judge whether the communication nodes of the links are connected with the control master station. According to the connection between the link communication node and the control master station, the switching load and switching load of the electric cyber physical system in different operating states are calculated, and the optimal switching load of the electric cyber physical system in different operating states is obtained. This method can clearly identify the vulnerable link in the electric cyber physical system, so as to monitor the vulnerable link and strengthen the link strength.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125107469","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}
