Compared to the conventional switching scheme, in this new method stepped waveforms with more than N possible kind could be synthesized. As a result, it is more achievable to compute the proper set of switching angles, especially at the low-modulation index to gain SHE for multilevel inverters. The controlling purpose is to eliminate selective harmonics and also fundamental output voltage control for a cascade LI-Ievel inverter. Finding an optimal set of switching angles for above objective function requires solving a nonlinear equation that is solved by the use of shuffled frog leaping algorithm in this paper. Simulation results are presented using Matlab environment to verify the suggested technique.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134233291","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}

These include single- and three-phase unidirectional and bidirectional buck, boost, buck-boost, multilevel, and multipulse topologies. The Vienna rectifier is a unidirectional boost type IPQC that has both single- and three-phase topologies. Like most boost type IPQCs, the Vienna rectifier is amenable to input current wave shaping techniques. In this paper, the efficacy of hysteresis current control (BCC) technique to confer improved power quality in two three-phase, four-wire Vienna rectifier topologies is assessed. MATLAB simulations of the topologies with BCC have been conducted and relevant data have been recorded. The simulation results, indicating compliance of the various parameters on the ac and dc sides with the current power quality norms, are presented.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132499268","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 this proposed system we can promote Smart institutions with rich sustainability and better supervision over the grid. The costs on electricity consumption of educational Institutions have been rising enormously since the last decade. There have been no measures taken to monitor the individual energy demand throughout the day which plays a major role in the calculation of electricity bill. The HEI spend more on heating, air conditioning and lighting load than on any other expense. This paper proposes a simple solution that shall keep the rising electricity bills in limits. The energy costs can be reduced by proper management of electricity distribution among various sections in the campus. This paper briefly confers the different methods that have to be put into practice in order to control the Energy demand. Also, this paper discusses about an innovative building automation and energy management system that is core to the institution's comfort and Sustainability requirements.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125596577","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}

Although these conventional reactors can limit sudden increase in load current, however the voltage profile of the respective buses deteriorates. Subsequently series Flexible AC transmission systems (FACTS) devices have been a feasible solution to limit sudden load currents while maintaining the voltage profile at buses. Among the latest series FACTS devices, the most prominent device, is the Interline power flow controller (IPFC).

The sluggish transient performance of voltage/frequency (V/Hz) control of induction motor drive is of course overcome by traditional decoupling control, where three phase quantities are transformed into two phase quantities. The controller performance in decoupling control is nevertheless affected by temperature variation. It is well-known that temperature variation will affect the rotor and stator resistance variations in the drive, and hence mismatches the values of rotor and stator resistances in the controller. Therefore, the performance of the drive is degraded in terms of torque, flux and currents in decoupling control. Efforts are made to improve the performance of the drive by estimating and adapting the temperature dependent parameters. The paper reviews the various online stator and rotor resistance estimation methods including soft computing techniques to improve the performance of the drive.","PeriodicalId":134828,"journal":{"name":"2018 4th International Conference on Electrical Energy Systems (ICEES)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128096260","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}

Dissimilar methods including classical and experimental methods have been utilized to address the problem successfully. It is detected that achievement of heuristic techniques largely be contingent on the selection of some user control parameters. Numerous turns are essential to discovery the optimal values of control parameters. Again these parameters are usually problematic needy. In other words, for different problems these parameters are to be selected separately. A wrong parameter selection may even lead to premature convergence. No particular rule is available for setting these parameters. A new improved hybrid algorithm for optimal reactive power planning (ORPP) problem combining with chaos theory is proposed in this paper. A self-adaptive parameter automation strategy is adopted is this paper. For the present work, tent map chaotic sequence is used and the proposed technique is termed as tent map differential evolution (TMDE). The possible locations for installation reactive power compensating devices are found using New Voltage Stability Index (NVSI) method. Minimization of loss and system cost are taken into account in problem formulation. The planned algorithm is beneficial on IEEE-30 bus system in order to verify its success and efficiency.
