The hybrid system consists of a Photovoltaic (PV) array and a Proton Exchange Membrane Fuel cell (PEMFC). Due to the intermittent nature of the solar energy the PV array becomes uncontrollable in delivering maximum power to the load. In coordination with the PEMFC the hybrid system output power becomes controllable. The coordination of the two control modes Unit Power Control (UPC) mode and feeder-flow control (FFC) mode can be applied to the system. In UPC mode the DGs regulate the voltage magnitude at the connection point where source power is injected. In this mode if a load increases anywhere in the micro-grid the extra power comes from the grid, since the hybrid source regulates power output to a constant. In FFC mode the DGs regulate the voltage magnitude at the connection point and the power flowing in the feeder. In FFC mode extra load demands are picked up by the DGs which maintain a constant load from utility point of view. The proposed control strategies always operate the PV array at the maximum output power and the PEMFC at its high efficiency band improving the performance of the system operation with reduced number of mode changes.","PeriodicalId":176900,"journal":{"name":"2013 International Conference on Power, Energy and Control (ICPEC)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121118677","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 estimation of efficiency is the primary step in the energy management. Number of efficiency estimation methods were analyzed and compared and airgap torque method is found to be accurate. It was suggested to have non-intrusive methods of testing rather than intrusive methods. The paper aims to incorporate sensorless speed estimation by speed observer, resistance estimation by dc signal injection method and losses estimation according to the IEEE standards in the airgap torque method to make this nonintrusive. This method is called modified AGT method. The authenticity of this method is verified by simulations.

In this paper, one-dimensional, steady state model for PEM fuel cell stack is developed in MATLAB environment and the effect of various overpotentials on the polarization and the efficiency of fuel cell are studied. At low current draw, there is a sudden increase in activation overpotential due to the slow electron transfer rate and a portion of the electrode voltage is lost to compensate for the lack of electro-catalytic activity. At all current draw, ohmic losses are linear with current density due to the low conductivity of membrane. At higher current draw, the electrochemical reactions are hindered by the water generated at the cathode and voltage drops. Efficiency drops with increasing power density; hence there is a trade-off between high power and high efficiency. Fuel cell system designers must select the desired operating range according to whether efficiency or power is paramount for the given application.","PeriodicalId":176900,"journal":{"name":"2013 International Conference on Power, Energy and Control (ICPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117217047","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}

Mica composite serves the machine as potential barrier for asphalt bonded insulation of 1940s, resin rich epoxy system of 1960s and existing global vacuum pressure impregnation with varied electrical field strengths in hostile atmospheres in power plants. Operational stresses disintegrate the micaceous insulation due to ionization of micro voids. A prominent diagnosis dielectric test for ages is Tan δ to assess over all integrity of winding's insulation. Emphasis is made in this paper on characteristic behavior of dielectric loss factor on various insulation systems of generator stator windings. Tests had been performed on machines of as old as half a century to latest half a decade operating life in power plants.

This paper mainly concentrates on proposing a planning process considering geographical and technical analysis, with indications where economic analysis needs to be carried. Generally, when transmission network planning process is initiated, the utilities assume the line length for technical analysis based on their expertise. After geographical analysis, the initial assumed line length changes which is largely neglected by utilities. A simple case has been illustrated to demonstrate the deviation in voltage profile and compensation requirements due to change in line length.","PeriodicalId":176900,"journal":{"name":"2013 International Conference on Power, Energy and Control (ICPEC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130334187","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}
