Energy issues being the most critical one need prime attention and prevention. This paper presents methods for power consumption reduction in multiprocessor systems by optimally allocating the jobs and scheduling them. The job allocation in multiprocessor systems is very crucial and a novel allocation algorithm for reducing the number of processors is proposed in this work. Scheduling decisions are vital for the system to meet both temporal and functional requirements and is perfect when methods for energy consumption reduction are incorporated into it. The current work aims to reduce power consumption of an embedded processor by Dynamic Voltage Frequency Scaling (DVFS) technique. The simulation results show a considerable amount of reduction in processor utilization and power consumption.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129766768","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 order to balance the growing needs, distributed generation (DG) can help to a large extent. Micro-grids (MG), mainly inverter based, are gaining more and more importance as they can accommodate various types of DGs effectively and for their superior power quality. A MG can be operated in two modes, grid connected and islanded mode. Each mode has its own control strategy. In this paper a control strategy for inverter based MG which can ensure stability and proper power sharing among the inverters, in islanded mode, is proposed. In a MG, the output impedance of inverter can have much impact on load sharing of inverters. The proposed control scheme uses second order general integrator in conjunction with indirect operation of droop method, to enhance the stability and power sharing in MG.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129992391","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}

DC-DC converter is used to step up the DC voltage from PV arrays and then it is connected to an inverter for AC applications. Conventional inverters have many issues like non sinusoidal output, high total harmonic distortion (THD), high switching stress and more number of switches. So multilevel inverter (MLI) have gained much importance over conventional inverters for high voltage and high power applications, due to the increased number of voltage levels producing less number of harmonics. In this paper, a cascaded asymmetric multilevel inverter is proposed which contains minimum number of switches and can be employed in AC applications using solar energy. The proposed topology consists of 25 output levels using 10 switches with near sinusoidal output, thereby reducing gate driver circuitry and optimizing circuit layout. Asymmetric multilevel inverter is more advantageous than symmetric multilevel inverter in obtaining more number of output levels using same number of voltage sources. The other advantages of proposed topology are low voltage stress and reduced THD. The THD for proposed inverter circuit is only 4.98%. Modeling and simulation is carried out using MATLAB/SIMULINK.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133881690","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}

PV module is increasingly employed in utilizing the sun's energy for generating electrical energy. The photovoltaic pumping has become one of the most promising fields in photovoltaic applications especially in remote locations. As the output characteristic of a photovoltaic module is nonlinear and changes with solar irradiation and cell's temperature so attention is paid to their design and their optimal use. Therefore a Maximum Power Point Tracking (MPPT) technique is needed to maximize the produced energy. In this paper, the proposed work is to extract maximum power from the PV array to powered water pumping system. Boost converter with Constant voltage MPPT (CVMPPT) technique is employed to drive centrifugal pump through permanent magnet DC motor. The 1KWp solar PV array is designed and modeled in MATLAB Simulink environment. CVMPPT is implemented in Xilinx system generator which is interfaced with MATLAB Simulink to control the DC-DC boost converter model in order to extract power to drive PMDC motor. The detailed study is carried out and the results are presented.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127290816","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 requires their integration in smart grids on a common platform to deliver clean and uninterrupted power at low cost. The paper proposes to augment these sources on a common DC bus platform with control scheme of power sharing between them by MOSFET switching. This eases the system with the burden of synchronizing the sources as well as prevents it from oscillations and harmonics. Simulation based results demonstrate that proposed method provides effective control of power sharing between the different sources integrated on a common DC bus for aforesaid objectives and situations.

The dc voltage obtained from PV system is usually lower than the peak value of the required output voltage of inverter and varies in a wide range. A power transformer is required to step-up the output voltage or a dc-dc converter is required to boost the input dc voltage, in addition to the dc-ac inverter, which increase cost and circuit complexity. Z-source single stage inverters with bulk inductors and capacitors are used in some topologies, but the harmonic content in the output is relatively high. In this paper, a solar photovoltaic (PV) fed single stage boost inverter feeding a three phase induction motor is explained with mathematical expressions and computer simulations. A time independent pulse width modulation technique is adopted in this system, which generates symmetrical gate pulse pattern resulting in smooth output waveforms. The dc link inductor can be kept very low as the inductor current is maintained constant by this discrete switching control strategy. This system is simple, cost effective and can be used for stand-alone solar applications. Results obtained from this system confirm the effectiveness of new discrete switching strategy and prove its capability to perform real time.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115155613","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}
