The proposed electronic ballast is the combination of a buck-boost AC-DC converter as a power factor regulator (PFR) operating in the continuous conduction mode (CCM) and a half bridge series resonant inverter (HBSRI), which is used for converting a constant dc link voltage into high frequency AC voltage to drive the fluorescent lamp. The design, modeling and simulation of this topology are performed in MATLAB-Simulink for an 18 W, 220 V, 50 Hz compact fluorescent lamp. With the utilization of proper commutation techniques like zero voltage switching (ZVS), the switching losses are reduced at high operating frequency of 60 kHz. The power quality indices such as displacement power factor (DPF), distortion factor (DF), total harmonic distortion of AC mains current (THDi), power factor (PF) and crest factor (CF) are evaluated for proposed electronic ballast, which is in the confirmation with IEC-61000-3-2 class C requirements.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117157197","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 paper presents a PSCAD/EMTDC based model for the solar powered micro-grid with EVs. EVs are expected to have both the vehicle-to-grid (V2G) and grid-to-vehicle (G2V) capability, through which energy can either be injected into or extracted from the solar powered micro-grid to control its energy imbalance. Using the model, the behaviour of the micro-grid is investigated under a given load profile, and the results indicate that a minimum number of EVs are required to meet the energy imbalance and it is time dependent and influenced by various factors such as depth of charge, commuting profiles, reliability etc..","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125838459","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}

Now-a-days the development of a country is measured by the energy consumption rate of that country. Bangladesh's energy infrastructures are quite small, insufficient and poorly managed with per capita energy consumption of 220KWh only. Bangladesh is steadily climbing up the development ladder and industries are shifting towards automation process. Energy and power need to act as a key catalyst in helping Bangladesh in this endeavor. The installed capacity of the power plants of Bangladesh is around 8000MW for supporting the demand of around 7000MW. However due to failure in the proper fuel management in the last few years the whole country is suffering from 1500-1800MW of shortage. In order to cater the growing demand and sustain the development phase it is the high time to think about the underground coal as the ultimate choice. This paper is one such attempt in pointing out the possible energy resources for electricity generation in Bangladesh with the help of scientific analysis and available statistics.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"40 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120917198","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 objective of this study was to analyze the effectiveness of load management and battery storage in residential grid connected PV systems without net metering. The power consumption of the home loads was divided into time manageable, storage capable and non-manageable. Load management to displace the time manageable and storage capable loads from evening hours to PV generation hours increased self-consumption by up to 50%. The addition of batteries to a grid tied PV system can increase self consumption to 100%, but there was no net cost savings due to the cost of the batteries and power conditioning unit. Grid tied PV systems with no net metering should be designed for daytime loads only to maximize cost effectiveness.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133283199","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 topology has been used for ac-ac conversion for various applications that involve variable voltage and variable frequency. Various pulse width modulation (PWM) techniques have been implemented in the topology to reduce the harmonic distortion and obtain better power quality parameters at the output. In this paper the symmetrical multipulse modulation technique (SMM) has been implemented in the single-phase matrix converter. The ability of the converter to deliver variable voltage at a specific fundamental (source) frequency and variable voltage at variable fundamental frequency with the technique has been assessed and experimental results are presented. The SMM is a simple method that involves two key parameters - the number of equal width pulses per half cycle (M) of the supply and the duty cycle of the pulses (δ). The performance of the single-phase matrix converter is assessed for control strategies that involve a fixed value of M and variable δ; and vice-versa.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121745070","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}

Typically, bidirectional IPT systems consist of high order resonant networks, and therefore, the control of bidirectional IPT systems has always been a difficulty. To date several different controllers have been reported, but these have been designed using steady-state models, which invariably, are incapable of providing an accurate insight into the dynamic behaviour of the system A dynamic state-space model of a bidirectional IPT system has been reported. However, currently this model has not been used to optimise the design of controllers. Therefore, this paper proposes an optimised controller based on the dynamic model. To verify the operation of the proposed controller simulated results of the optimised controller and simulated results of another controller are compared. Results indicate that the proposed controller is capable of accurately and stably controlling the power flow in a bidirectional IPT system.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123832719","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}

MHP has been playing a significant role for electrification of the remote rural areas of the Nepal. Generally, 50 % overall efficiency is adopted while designing the MHP without consideration of the sizes of the plants due to the lack of testing facilities of such domestically made turbine before installation. The field test was conducted, in each individual powerhouse, using additional dump load (ADL) method. In this method, the consumer load and Electronic Load Controller (ELC) were disconnected and terminals of the ADL were connected to generator. During the testing ADL was switched on 1 kW interval and the discharge was controlled through the gate valve by maintaining frequency of 50 Hz. The corresponding discharge was recorded along with net head, current and voltage. Then the flow versus overall efficiency of the plant gives the maximum water to wire efficiency of the plant at a given discharge.","PeriodicalId":256740,"journal":{"name":"2012 IEEE Third International Conference on Sustainable Energy Technologies (ICSET)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125484485","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}
