The transformation of energy is of critical importance. The fundamental approach is to achieve clean alternatives on the energy supply side and energy alternatives on the energy consumption side. However, the demand of renewable energy acceptance has not been analyzed and confirmed. In this paper, the global renewable energy demand model has been built and simulated based on the artificial bee colony optimization algorithm in order to analyze the demand of renewable energy acceptance, integrated with the Model for the assessment of greenhouse gas induced climate change, which is also called the MAGICC. The calculation performs the optimization of the object function, which takes the generation performance standard and human development index into consideration, with the proportion of installed capacity of different generator units in Asia, Europe, Africa, North America, South America and Oceania as the variable quantity. As the result of the simulation, the empirical analysis of global demand acceptance of the year 2030 and 2050 were carried out, which shows the green electricity demand acceptance demonstrated by the installed capacity in six continents.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114394960","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}

First, the zero-sequence signal is processed by empirical mode decomposition and Fast Fourier Transform to extract the three fault feature quantities of the IMF energy, the fifth harmonic component, and the active power component; then the concept of the fault measure is introduced, and the fault measure function is used to calculate Three fault measures of feature quantities are used, and fault measures are used as feature input vectors for information fusion; finally, least squares support vector machine (LSSVM) classifiers are used as information fusion line selection algorithms to classify the model accuracy and generalization. On the problem of the parameter selection that has a greater impact on the capability, the particle swarm optimization algorithm (PSO) is used to optimize the parameters, and the PSO-LSSVM fault line selection model is established using the optimized parameters. By modeling the small current grounding system in PSCAD and using MATLAB to process data, the results show that the model improves the accuracy of fault line selection.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121304001","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 general, the energy source of a satellite power system from the solar array panel with the material of the triple junction GaAs which output I-V power curve with high fill factor. However, the general commercial simulator products cannot simulate the I-V curve with high fill factor because the higher the fill factor of the I-V curve is, the more severe the nonlinear effect of the I-V outer-loop is. This paper proposes a novel I-V outer loop control method with working point control method that control the output current and output voltage simultaneously based on coordinated working of two power units, the current control unit (CCU) and voltage control unit (VCU), solving the nonlinear control problem of the I-V curve with high fill factor perfectly. The I-V outer loop includes two parts; the first part of the input is the SAS output voltage information, and output the expected operating current reference voltage information required by the CCU. And the second part of the input is the SAS output current information, the output is the desired control voltage reference information required by VCS. Through the coordination of the two parts of the I-V outer loop with CCU and VCU, the SAS can directly output the desired working points on the I-V curve whatever the nonlinear characteristics of the I-V curve is. Finally, under the simulation experiment of 60V open-circuit voltage and 2A short-circuit current, it is verified that the control method can simulate any nonlinear I-V curve, and it can also show good dynamic response performance under the 1-kHz load switching frequency.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127851566","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}
