Due to advantages of RE on the technology reliability and cost front, system designers are looking for ways to combine both generators - renewable and fossil fuel based into one system known as hybrid power system. Therefore, hybrid power system is used to reduce the dependency either on conventional energy or RE systems (RES). This paper deals with the sizing, generator running hours, sensitivity analysis, optimization, and green house gas (GHG) emission. For this purpose two different locations have been selected where feasibility of hybrid renewable energy systems (HRES) is analyzed for the same load demand using different suitable RES. One site is a small remote community of Amini in Lakshadweep Islands, located in southern India in the Arabian Sea, where solar or wind energy is always available throughout the year to provide energy security. Another place is a rural township of Hathras, in northern Indian State of Uttar Pradesh, where agricultural biomass is found in abundance for whole year. For optimizing and simulating the system requirements, practical data is used in the HOMER software of National Renewable Energy laboratory, USA.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126540755","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, it is found that Jatropha oil contains some phorbol esters, which are a toxic compound. In this work, phorbol ester distribution of jatropha portions, including seed, seed cake, seed oil, kernel seed, seed hull, kernel cake and kernel oil, were firstly studied. The results found that a majority of phorbol ester was found in kernel oil and seed oil at 0.45 and 0.33 mg/g, respectively. These compounds can cause some biological effects such as inflammation and tumor promotion. Therefore, detoxification of phorbol ester must be performed. High quality biodiesel continuous production plant under JST-JICA SATREPS collaboration project was established with capacity to produce biodiesel that meets the EAS-ERIA standard [1]. The biodiesel plant consists of raw material dehydration, esterification, transesterification, biodiesel washing, dehydration and upgrading, which has affected the phorbol ester differently. Consequently, the changes of phorbol ester content were examined in each process by using High Performance Liquid Chromatogram (HPLC) technique. The results show that some of these processes can reduce the toxic content of biodiesel. Phorbol ester quantity was decreased by 77.55 % after esterification process, and this toxic content could be significantly eliminated after transesterification by 89.80%. Furthermore, the phorbol ester of 0.03 mg/g in biodiesel was detected after partial hydrogenation unit. The percentage removal of hydrogenation process was 95.92%.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127906589","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}

Comparing the energy consumption, life cycle costs, temperature and humidity controls to the conventional cooling system control were done. The experiment demonstrated that the energy consumption of the cooling system decreased 87.98% and the overall energy consumption decreased 35.49% as compared to the convention cooling system. The annual cost of the proposed system can reduce up to 288,533 THB/Room with 1 year of return of investment.

The data were collected from both secondary and primary sources. The primary data concerning the total production and composition of solid waste were collected from different local institutions associated with solid waste management and that concerning technology of production of thermoelectric power from bagasse from Pattoki Sugar Mill and from oil fuel from Thermal Power Station Faisalabad who also supplied the prices of machinery and equipment. The data were used to design different projects that were subsequently appraised by discounted cash flow technique to determine their B/C ratio, NPV while Payback period was determined by traditional method. The enquiry indicated that currently, Lahore consumes approximately about 1,000mw/hr electricity and produces approximately 5,700 ton/day of solid waste. The electricity that can be produced from Lahore solid waste with an initial fixed investment of $29,272,333 turned out to be 85.5mwh, which forms about 1/11th of the total consumption of Lahore. The best part of the message was that the electricity from this source can be produced at the cost of less than rupee one ($0.0166670) per unit.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114892113","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 achieved national regulations for buildings in Thailand, such as building code and green building, are the guideline to set up the optimal energy policy. Therefore, the banking recognizes the importance of the energy policy with business condition. According to the various bank in Thailand, the advertising and promotion of bank is very important for increasing the market share, so the sign lighting system is the first sign of bank which are needed to install without energy concern. For small and medium sizes of bank in Thailand (approximate 4,000 building), more than one third of lighting system is sign lighting which is proposed only advertising objective. This paper introduces the optimal energy management of sign lighting to reduce the energy consumption without effect to the advertising objective, which remained the illumination need and acceptable investment of sign lighting. In addition, two technologies of the sign lighting system for advertising are proposed to evaluate the energy performance, which are T5 fluorescent lamps with electronic ballast and Light Emitting Diode (LED) lamps compare to the existing system with T8 fluorescent lamp and low loss ballast. The experimental results show that the LED lamps sign lighting can reduce the energy consumption more than 50% with the significant feasibility in practical implementation. Finally, the environment aspect will be presented in term of CO2 reduction and the barriers of LED lamps sign lighting will be concluded.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114956127","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 effects of on-load tap changer (OLTC), over-excitation limiter (OLE), and high voltage direct current (HVDC) link on voltage stability are also analyzed. In which, the converter terminals of HVDC link are considered as a constant real and reactive power load under steady state and the effects of HVDC control modes on voltage stability are also studied. A practical system of larger grid (Taiwan grid) connecting to a smaller island grid (Peng-Hu grid) via two circuits of long submarine cables is used to study. The strategies for improving voltage stability include reactive power support and under-voltage load shedding (UVLS) are proposed. Based on the simulation results, it shows that the voltage response characteristics are affected significantly by different load patterns. The OLTC plays an important role during the load voltage restoration. The reactive power support devices and UVLS can improve the short-term voltage stability, which makes the power system achieve voltage stability operation. However, the interactions between OLTC and OEL under HVDC link connected operation would lead the power system to voltage instability. The constant current control mode of HVDC link has better effect on voltage stability. All of these studies are performed by software package, namely power system simulation for engineering (PSS/E) in this paper.","PeriodicalId":262691,"journal":{"name":"2011 International Conference & Utility Exhibition on Power and Energy Systems: Issues and Prospects for Asia (ICUE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126582562","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}
