In the present research of MMG, it is focused on filtering the original signals rather than locating change points. Therefore, this paper considers this approach to detect abrupt changes. For the purpose of evaluating the performance of different algorithms, the True Positive Rate (TPR) and the F-score are employed in this paper. The simulation studies have been carried out on low-frequency signals and high-frequency signals from the Reference Energy Disaggregation Data Set (REDD) respectively. The MMG algorithm, which has the advantages of high accuracy and fast calculation speed, is superior for both two types of signals. In addition, it can provide not only the information of the position of a change but also the direction of a change. The results demonstrate that the MMG algorithm shows better performance than the CUmulative SUM (CUSUM), the Bayesian Information Criterion (BIC) and the Generalized Likelihood Ratio (GLR) algorithms.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122452186","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}

Generally, the ES uses second-order eneralized integrator phase locked loop (SOGI-PLL) to track the voltage and frequency of power grid, and uses proportional-integral (PI) controller to stabilize the critical load (CL) voltage. However, for microgrids with large voltage and frequency fluctuations, the conventional ES control method is difficult to stabilize the CL voltage quickly and accurately. To solve this problem, an ES control method based on cascade second-order generalized integrator phase locked loop (CSOGI-PLL) and simplified brain emotional learning based intelligent controller (BELBIC) is proposed in this paper. By using the frequency adaptive tracking characteristic of CSOGI-PLL, the ability of ES to stabilize CL voltage in power grid with large frequency variation is improved. An ES control method based on simplified BELBIC is proposed, which uses its self-learning ability to automatically adjust control parameters and improve the control speed of ES. To verify the feasibility of the proposed scheme, the ES is modeled and simulated by MATLAB/Simulink and verified by dSPACE platform. The results show that the method is effective and feasible.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"80 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121206069","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}

Therefore, for step wise PV power forecast methods, the accuracy of solar irradiance forecast is very important. However, the diversity of irradiance fluctuation patterns brings great challenges to PV power predictions and limits the application of existing forecast models. In this paper, a novel solar irradiance forecast model of ultra-short-term time scale is proposed, which using complex network analysis to identify the irradiance and classification modeling to realize classified forecast of irradiance. Firstly, 4 irradiance fluctuation patterns are defined according to the local historical irradiance data, then 4 BP neural networks (BPNN) are built and trained respectively using these data of different fluctuation patterns. Secondly, each four-hour irradiance series is transformed into complex network based on weighted horizontal visibility algorithm (WHVG), then three complex network features are extracted to analysis not only the time series characteristics but also the network topology of irradiance data sequence. Thirdly, the support vector machine (SVM) is used to identify the irradiance fluctuation pattern with complex network features, and the corresponding BPNN is applied to forecast the future irradiance. The accuracy of irradiance pattern identification and the subsequent classified ultra-short-term irradiance forecast are verified by simulation with two-years actual irradiance data in Mississippi, US.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127770671","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}

Generally more failures are occurring in the system and the largest portion of these faults come from the distribution network. The concept of the microgrid is considered to be a solution to this issue. Microgrids should achieve smart and robust load restoration, in which a decision is made on which load should be supplied first and what are the loads that follow. In this paper, a smart, dynamic load priority list will be modeled using artificial neural network (ANN), where different categories of loads such as residential, commercial, industrial and hospital will be prioritized for restoration based on the given time, reliability indices and amount of available energy. The ANN based priority list showed exceptional results in terms of flexibility and understanding of the current energy and reliability status. The results can be further used as an input direct load control functions to intelligently determine which loads should be curtailed and which ones are uninterruptible.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127794710","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}
