Micro-Trigeneration system is an effective way of efficient utilization of fuel as an energy source. Around 60% of power in India is generated by conventional methods where 35% of fuel energy is converted into electricity. The rest of the energy is wasted thus affecting economy and environment adversely. Electricity is available for consumer with significant distribution and transmission losses. In such a scenario, generation of electricity at the point of use with maximum utilization of fuel energy is an effective way of avoiding generation and distribution losses. This is the objective of a Micro-Trigeneration system. Trigeneration is a step ahead of cogeneration plants which are used for Combined Heating, Cooling and Production of electricity (CHCP) using single fuel. For experimental proof of the concept, a LPG driven Bajaj 4-stroke IC engine was used as the prime mover. The energy available from engine is utilized for running the compressor of air conditioner and a generator. The former produces cooling of a cabin and the latter generates electricity to illuminate the cabin, run a fan inside the cabin and charge a battery. The heat of exhaust gas from the engine is recovered for water heating by using a heat exchanger. Thus combined heating, cooling and production of electricity is achieved at source to fulfill local requirements. The micro-Trigeneration unit gives an overall efficiency of 96% in terms of fuel energy conversion into other useful forms curtailing energy loss to only 4% thus resulting in economical and environmental benefits. The successful operation of this project proves to be a precursor for the development of a commercial trigeneration system.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116187526","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}

By separating the solar radiation into two beams using a dichroic lens, simultaneous operation of a photovoltaic (PV) and a thermophotovoltaic (TPV) cell is made possible. Photons with a wavelength shorter than 1100 nm are reflected onto a PV cell; whereas the remaining solar spectrum is refracted towards a TPV cell. This testing platform takes advantage of auto-tracking and focusing capabilities using a digital mount and photoresistors. Alternative solutions to cooling problems have also been offered. Various concentration ratios, incident light intensities, acceptance angles and spot sizes can be achieved due to the versatile nature of this device. Issues with mismatching lattice constants have also been addressed through spectrum splitting. This design, when operated at its full capacity with a 3-junction PV cell and a TPV cell, allows for exciting new possibilities in high efficiency solar cell technology. These possibilities include the 3+1 hybrid multijunction cell design which could lead to higher overall efficiencies than conventional concentrators.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126914439","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}

While the initial volume of plug-in hybrid electric vehicles will only constitute a very small fraction of total automobiles sold, “clustered” purchasing patterns for these vehicles may result in large localized loads on the power distribution network. Additionally, high-penetration deployment of variable generation sources will decrease flexibility in the power system. Previous research has indicated that plug-ins may be used as grid resources with no significant impact on fuel consumption. Deterministic 1- and 2-way communication architectures were modeled to show how real-time vehicle-grid interactions might occur. This analysis uses GPS travel survey data, grid-wide load data, and distribution-system load data to determine the effective power and energy storage capacity of a charging plug-in fleet, given actual driver behavior. The power utility controls vehicle charging rates based on the area control error and distribution transformer overheating. The cost of regulation and distribution transformer wear was calculated to determine the value potential of different data communication methods controlling a fleet of plug-in hybrids.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114394216","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}

However, operators lack effective and accurate tools for real-time monitoring and control of power systems. The U.S. Department of Energy, along with several utilities and system operators, is making a major $108 million investment in the Western Interconnection for phasor measurement unit (PMU) installation and phasor application development. This phasor measurement network opens up many opportunities for the estimation and prediction of power system states in real time, which enable operators to evaluate the system dynamic security in advance and allow them more time to respond to disturbances. Kalman filter based dynamic state estimation offers a solution suitable for this purpose. Our work indicates that the performance of Kalman filters in dynamic state estimation would degrade if PMU measurements cannot adequately capture the system dynamics. This paper develops a framework to identify how to place PMUs to improve dynamic observability of the power grid. Simulation results validate the concept, and the guidelines for PMU placement are derived.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"554 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133599321","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}
