Remarkably high electrical efficiency at attractive economics can be achieved by using Ce0.8Gd1.2O1.2 (Gadolinium Doped Ceria (GDC)) as solid electrolyte in IT-SOFC (Intermediate Temperature-Solid Oxide Fuel Cell) and using La1-xSrxCo1-yFeyO3-δ (LSCF) as cathode where, 0 <; x ≤ 0.5, 0 <; y ≤0.8. Different solid oxide electrolyte samples were synthesized employing dry pressing technique, thereafter the samples were sintered at different temperatures ranging from 1350°C to 1600°C. Relative density as high as 93.93% was achieved for electrolyte samples. X-Ray Diffraction (XRD) pattern for sintered GDC samples reveals the presence of crystalline crystallographic system of cubic phases with crystal orientation such as (111), (200), (220), (311), (222), (400), (331), (420), thereby ensuring productive sintering. Impedance Analysis at different temperatures indicates that the ionic conductivity increases with the increase in sintering temperature and was found to attain its peak value at 1550 °C. Exceptionally high power density of 347mW/cm2, 539mW/cm2 and 747mW/cm2 of 700 °C, 750°C and 800 °C were achieved indicating excellent electrolytic performance. This justified the competency of GDC to replace conventional YSZ (Yttrium Stabilized Zirconia) electrolyte. Further, different cathode samples were synthesized using combustion synthesis technique, thereafter the samples were sintered at different temperatures ranging from 1050°C to 1150°C for 4 hours in air. Single phase rhombohedral of LSCF is obtained and is confirmed by the peaks corresponding to (104), (110), (024), (300) and (306). Surface area of the sample having highest cobalt concentration is found to be much higher than other samples, that is, 14.579 m2/g. TG graphs shows that drastic weight loss occurs in three steps in the temperature range of 195-200 °C, 300-340 °C and 430-460 °C. Arrhenius plot suggests that DC conductivity increases with increase in densification for sample having lowest cobalt concentration while decreases in case of other samples, Of all the prepared samples, La0.54Sr0.4Co0.8Fe0.2O3±δ was found to be most efficient as it achieved current density as high as 2.12A/cm2 at 800 °C under cell operation voltage of 0.7 V. Hence the GDC electrolyte and LSCF cathode IT-SOFC fuel cell system can deliver attractive economics and consequently can be used for the production of clean energy allowing sustainable development.

The future power distribution system which aims for an intensive penetration of Distributed generators (DGs) makes the power system operation and planning more challenging. This paper investigates the effectiveness of different methods for optimal allocation and sizing of DGs in autonomous and non-autonomous micro-grid modes based on the voltage profile, power losses, total DG size and reliability. In the proposed work initially, an effective power flow based loss sensitivity factor (LSF) method and active power injection based LSF method for DG allocation are compared in non-autonomous micro-grid mode. After siting DGs, LSF based optimal sizing has been executed in non-autonomous mode micro-grid operation. Later, the micro-grid has been converted into autonomous mode based on the optimal sizing and siting of DGs in non-autonomous mode operation. Additionally, the obtained results have been improved by PSO-TVIW based sizing method. The proposed methodology is adopted in standard IEEE 33 bus radial system which has been converted into autonomous micro-grid for verification.

This paper presents an advanced method for condition monitoring of oil-paper insulation of the transformer using accelerated dielectric response measurement. In frequency domain spectroscopy, dielectric response current is measured for a period of two cycles over a wide range of frequencies. Such measurements on real life transformers take long time in practice especially in the lower frequency range which is practically problematic. Considering the above-said fact, a new technique has been developed in the present work that can reduce the measurement time significantly. Instead of using the excitation for two cycles, quarter cycle of the excitation is applied on insulation under test. The method is verified on three test samples having different preset moisture contents. The dielectric dissipation factors of the test samples computed from the proposed method, are then compared with the corresponding values calculated for two cycles of the applied excitation. The results show negligible differences in the values of dissipation factors of the test samples obtained with the applied excitation for two cycles with that of quarter cycle.

This paper deals with a new intelligent system which monitors the health condition of a three phase induction motor by using infrared thermal images. Here two systems, real time and off line, are proposed to monitor the temperature variations and analyze the hot regions beyond the rated temperature in the three phase induction motor using infrared thermograms. This system helps to monitor the variation of temperature at the different parts of the induction motor. Abnormal temperature rise in any parts indicates the faults. This technique helps to prevent the parts of induction motor before any catastrophe would happen in the future. The color based segmentation technique is used to identify abnormal hot regions in the thermograms of three phase induction motor. A changing red color intensity algorithm is also implemented to recognize the hot spots and also the change in hotness in a particular area of induction motor to declare the health of that particular area. Similarly the conditions of various areas in the machine all together monitor the overall health of the Induction motor.

This paper proposes a solution for harmonic mitigation in high voltage DC transmission (HVDC) system through 18-pulse transformer fed voltage source converter (VSC). A phase locked loop (PLL) based current controller is proposed in this paper for power quality (PQ) improvement at input AC mains in coordination with DC link voltage control. The proposed system is modeled in MATLAB-SIMULINK environment and its performance is evaluated under various transient conditions such as load decrement, load increment, load variation, single phase fault condition and non-linear load connection for short duration at points-of-common coupling (PCC). The obtained results are presented to demonstrate the effectiveness of the proposed system for harmonic mitigation.

In this paper, reactive power cost function has been obtained for generator to supply reactive power based on the operating point of the generators on its capability curve. Based on the reactive power cost functions, a non-linear optimization problem is solved to compute both real and reactive power prices for pool electricity market model considering the minimization of fuel and reactive power cost. A upstream looking algorithm has been used to find the contribution of each generator to the load and the based on proportional sharing the marginal prices at each node have been determined for both real and reactive power to be paid to generators. The results have been determined for IEEE 24 bus test system. The results have been compared for already reported methods to determine reactive power cost.

Clustering is one of the efficient techniques which not only help in protraction of lifetime of wireless sensor network but also make it scalable and robust. Subdivision of network into group of sensor nodes with a coordinator is called a cluster. Cluster members collect the physical data by sensing the environment and forward it to the coordinator which is generally termed as Cluster Head (CH). This cluster head aggregates the data and transmit it to the Base Station for further processing of data to meet the requirement of the application. In this paper we have proposed a novel self organising clustering scheme which considers the real time parameters for setting up the clusters for data collection. Unlike several proposed algorithm, this scheme reclusters the network only when CH fall below a threshold level. Repeated unnecessary clustering in every round depletes the energy of the network more quickly. We have introduced heterogeneity in the proposed work. By virtue of heterogeneity in terms of energy, lifetime of the network can be extended. An algorithm is functional if the area of interest is covered by active nodes. The period for which the network is functional is termed as persistent period in our paper. Simulation results show that the proposed scheme is comparatively more energy efficient, scalable & robust and has longer persistent period.

Electronic Load Controllers (ELC) are used to balance the power at generator terminal to maintain the frequency of the system at nominal value. Load controllers for micro hydro power plants have been an area of interest for researchers as well as for developers as it is of paramount importance to keep the frequency constant, which is not possible without controlling the load particularly in the case of micro hydro power plants. The present paper deals with use of an ELC for synchronous generator of micro hydro power plant of rating 60 KW in MATLAB Simulink. The design of ELC using a controlled bridge rectifier and IGBT chopper feeding a resistive dump load has been implemented for simulation in this paper. The power consumption of chopper has been varied by the duty cycle of the chopper. The simulation results have shown the changes in various parameters, i.e., excitation voltage, stator current, mechanical power output, output power of generator, power across consumer load, and dump load as a result of the change in demand/load.

This paper presents a technique for the detection and localization of the power quality events associated with outage and grid synchronization of solar photovoltaic plant in distribution network. A standard IEEE 13 bus distribution network has been modified by adding 100kW solar photovoltaic plant. The proposed test system is simulated in MATLAB/simulink environment. Voltage signals captured at nodes of the test system are used for power quality analysis. The harmonic detection has been carried out using fast Fourier transform and the voltage sag, swell has been detected by voltage index calculated based on wavelet analysis. The unbalance in the voltage has been detected by sequence components of voltages. The power quality events associated with sudden change in the solar insolation have also been investigated. Detection and discrimination of synchronization, outage and sudden changes in solar insolation has been proposed using sequence components of voltages measured.

Detection and discrimination of synchronization, outage and sudden changes in solar insolation has been proposed using sequence components of voltages measured.","PeriodicalId":130355,"journal":{"name":"2015 International Conference on Energy Economics and Environment (ICEEE)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121093657","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}
