Yet, current sharing is prevalent in the parallel configuration due to the large forward voltage tolerance of high-power LEDs resulting in uneven light output and premature failure when they are “overdriven”. Current-matching techniques in practice involve complexity, high cost and reduced efficiency. In this paper, a Single Inductor Multiple Output (SIMO) parallel string LED driver with time multiplexing control which takes advantage of the inability of the human eye in visual perception of high-frequency operation in order to time-share the operation of individual strings is proposed. This shall greatly reduce the component count and complexity with less than 5% current mismatch. Soft start, dimming and shutdown features are achieved for enabling off-grid solar photovoltaic (PV)-based lighting. Also, the availability of the system is increased by introducing a LED failure protocol which has been validated by simulation and hardware implementation.","PeriodicalId":164446,"journal":{"name":"2016 IEEE International Conference on Sustainable Energy Technologies (ICSET)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126967281","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}

As such, the classical methods ensuring secure operation of power grids, which are largely developed several decades ago, need to be reassessed. At the same time, new generations of smart electronic devices provide fast actuation to smart power grids. Also, transmission resources are continuously installed into the system and will be ubiquitously available in the future. These assets provide new opportunities for power grids' operation controls. In this paper, we sketches the ideas of viable alternatives for traditional remedial actions of power grids with high penetration of renewables, in which the renewables are integrated with synchronverters to mimic the dynamics of conventional generators and transmission lines are equipped with FACTS devices. In these novel emergency control schemes, the power electronics resources are exploited to control the inertia/damping of the imitated generators as well as the susceptances of transmission lines in order to quickly stabilize the power system under emergency situations. The proposed controls are designed by solving convex optimization problems, making them scalable to large scale power grids. Also, these emergency control schemes can be implemented with minor investment by exploiting the plentiful transmission facilities ubiquitously available on the existing power grids.","PeriodicalId":164446,"journal":{"name":"2016 IEEE International Conference on Sustainable Energy Technologies (ICSET)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131057928","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}

This capacity has been rapidly increasing since the start of the feed-in tariff policy in 2012. The installed capacity after 2030 may be considerably larger than the current supposition if this trend continues. In this study, we conducted numerical simulations of the demand and supply operation with consideration of the unit commitment of conventional power generators using PV generation forecasting in economic-load dispatching control. This operation occurs in power systems with extremely large integrations of PV generation. The impact of PV generation forecasting errors on the demand and supply imbalance is quantitatively evaluated with consideration of the installed PV capacity as a parameter. Simulation results show that the impact of the forecasting errors becomes small for a larger value of the installed PV capacity. The results additionally reveal that efficient use of PV generation is more important in power systems with extremely large integrations of PV generation.","PeriodicalId":164446,"journal":{"name":"2016 IEEE International Conference on Sustainable Energy Technologies (ICSET)","volume":"213 0 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122826903","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}
