The system that best utilize the novel performance qualities when combined comes with a tradeoff that must be subjugated to have an enhanced performance. This work mainly considers the integration of the bandwidth efficient M-ary QAM, Multiple Input Multiple Output (MIMO) system and the Orthogonal Frequency Division Multiplexing (OFDM). The factor that motivates to integrate these techniques is the orthogonality of the subcarriers and the diversity of the MIMO systems. This work shows the performance graph for various MIMO-OFDM systems which are applicable for the present day technologies including 4G. But the detrimental aspect that needs to be considered while incorporating the techniques introduces a factor of issue that is Peak to Average Power Ratio. Generally this is analyzed using the Cumulative Distributive Function (CDF). The compensation when provided for this system to cut down the high PAPR will produce a proficient result. Hence a technique called Partial Transmit Sequence (PTS) is adopted for this work.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134359634","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}

Non-isolated high step-up DC-DC converters are required widely in the industrial applications. Many of these conventional DC-DC converters have the disadvantages of operating at high duty-cycle, high switch voltage stress and high diode peak current. A three-level step-up converter is implemented to boost the fuel cell stack voltage of 90V to 340V. This high DC link voltage is fed to the voltage source inverter and interfaced with the load. Two feedback control loops are designed to make the system operate in stable conditions. This system configuration is suitable for low-power applications. The Performance of the developed system is analyzed in MATLAB/Simulink environment under steady state and transient conditions.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130585575","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 unit cost of energy particularly from solar energy is much higher when compared with conventional energy sources. Nowadays, the emphasis is on the integrated utilization of these resources to minimize the cost and maximize the profit. In this paper, an optimal daily scheduling approach for a solar-wind-diesel system with battery storage has been presented. A mathematical model has been developed with the objective of maximizing profit. The problem has been optimized using Linear Programming technique using Primal-Dual Interior Point Method.

Contingency assessment has to be carried out to figure out the lines which are most vulnerable to instability. In this paper contingency assessment is done by a novel technique in which performance indices (PI) obtained from the variation of bus voltage magnitude and apparent power of the transmission line are taken into account with masking effect. The overall ranking of the severity of the contingencies is obtained through fuzzy logic. For this purpose we propose a three step technique: in first step the performance indices are obtained through power flow; in second step the masking effect is removed; fuzzy logic based overall ranking is obtained in the third step. The approach is illustrated on IEEE 14 bus system. This approach is suitable for different types of plots. By knowing the severity of the contingency the operator can sketch a control action in the real time before the system moves towards instability.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117280317","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 objective of protective relay coordination is to achieve selectivity without sacrificing sensitivity and quick fault clearance time. The calculation of the time dial setting (TDS) and the pickup current (Ip) setting of the relays is the core of the coordination study. The inequality constraints guarantee the coordination margin for each primary/backup relay pair having a fault very close to the primary relay. Using this formulation, the size of the optimization problem is significantly reduced. Genetic algorithm is the algorithm being applied to minimize the operating times of the relays. In this paper both linear and non linear equations are framed for the test bus system used and optimized using the genetic algorithm.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127708629","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}
