Reformulated equations for two-level schemes are proposed to satisfy the DE algorithm. Optimum solutions are found for odd value of switching angles (odd N) case within all range of modulation index M. The DE algorithm needs a relative small amount of generations to reach accurate solutions with appropriate control parameters. The comparison of some common variants in the DE shows that all variants may generate the same precision results by using their best specific crossover rate and mutation factor values. MATLAB/Simulink simulation results confirm that the solutions obtained by the proposed technique can be applied to eliminate the entire undesired specific harmonics as expected by the proposed formulation.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115640854","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}

Inverters are needed to convert the direct current electricity produced by the PV array into alternating current electricity required for loads. Nowadays, multilevel inverter gained so much popularity in PV systems. Multilevel inverter promises a lot of advantages over conventional inverter especially for high power applications. Some of the advantages are that the output waveform were improved since multilevel inverter produced nearly sinusoidal output voltage waveforms, hence the total harmonic distortion also low. The switching losses also become less. And, the filter needed to smooth the output voltage is small; hence, the system is compact, lighter and much cheaper.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127076593","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}

Using samples of input and output voltage, this control system makes the input current to follow a sinusoidal path. As a result, the line current's Total Harmonic Distortion (THD) is reduced and the input power factor is improved.

The penetration of wind power in power systems is increasing worldwide due to environmental constraints and fossil fuel depletion. The main difficulty, however, is accurate prediction of wind power which otherwise may lead to situation in network operation. For more safe and reliable operation, the penalty and reserve costs must be considered to account for power imbalance in the evaluation process. In this paper, an economic load dispatch problem (ED) for the system consisting of both thermal and wind generators is solved by brain storm optimization algorithm (BSO). The random behavior of wind power is modeled using weibull function. The factors such as overestimation and underestimation of available wind power due to power imbalance are included in cost function in addition to other classical economic dispatch terms. The proposed algorithm is tested with six standard test functions to prove its efficacy. Two test systems consisting six and forty units integrated to wind farm of comparable capacity are studied to determine the overall cost of operation.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128598822","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}

Normally, most of researcher used non-ferromagnetic rotor in double stator topologies to avoid saturation and higher production of cogging torque due to unsymmetrical flux distribution. Furthermore, parallel magnetic circuit is usually used for rectangular permanent magnetic due to easy fabrication cost rather than series magnetic circuit. But, in this research both parallel and series magnetic circuit is being applied using rectangular permanent magnet. Structure of the double stator BLDC with series magnetic circuit is proposed. Finite Element Analysis (FEA) is used as a tool to calculate the torque and cogging torque of each model. The Total harmonic distortion (THD) of the torque waveform is used for evaluation of the best torque characteristics. Furthermore, motor constant square density, G is used in comparing other model that's been reported. Based on the result, it is found that a proper selection of stator and rotor width could result lower THD on torque waveform due to good flux distribution. The double stator with series magnetic circuit topologies has several advantages compared to parallel magnetic circuit. However, consideration on cogging torque and magnetic saturation on the rotor should be taken account in designing this kind of double stator BLDC. Conclusively, the paper provides guidance in type selection of double stator BLDC with ferromagnetic rotor.","PeriodicalId":135966,"journal":{"name":"2012 IEEE International Conference on Power and Energy (PECon)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128603513","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}
