The hybrid system under investigation comprises of a hydropower station, a photovoltaic (PV) generator and a diesel engine, while the entire installation is also supported by the employment of a battery bank. According to the analysis of results obtained, reassessment of the current energy management plan is as proved necessary in order to raise restrictions posed to the energy contribution of the PV generator. For this purpose, the theoretical maximum energy contribution of the PV generator is estimated and replacement of the diesel engine operation is explored, with results obtained being rather encouraging for the system future operation.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132171721","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}

For this reason, the paper illustrates an economical comparison among innovative 325 kV four-phase ac lines, traditional 400 kV three-phase ac lines and increasingly-popular 500 kV HVDC lines. These systems are considered firstly in single-circuit and secondly in double-circuit overhead arrangement. The comparison is based on the main cost items that characterize these lines, namely investment costs, energy losses costs and reliability-related costs. The uncertainty of the relevant parameters, particularly significant as far as innovative four-phase ac lines are concerned, is also discussed.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116883655","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 biofuel feedstocks chosen represent the current situation of decentralized biodiesel production in Finland. The Finnish biodiesel production is based on the low value feedstocks that are mainly by-products of small-scale industry (e.g. food industry). The stabilities of these biofuels were measured by determining their Oxidation Stability Index (OSI) using the Rancimat method. The stabilizing effect of synthetic antioxidants (BHA and IONOL BF 1000) for oils and ester-type fuels used was determined. With different antioxidants, there were considerable differences between the stabilities of the oils and fats as well as of the esters made from these feedstocks.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125877992","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 analysis of the benefits of the proposed solution is done by comparing the circulating power of assets and also by analyzing the power factor.

Measured characteristics of illuminated polycrystalline-Si photovoltaic modules are modeled, and the apparent shunt current is analyzed. It is shown that an Ohmic-like behavior only takes place at voltages well below the maximum-power point. At higher voltages, the apparent shunt current quickly drops to negligible values. Modeling a crystalline-Si PV device with a fixed shunt resistance may therefore lead to underestimation of the maximum power exceeding 10% at certain irradiance levels.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124841530","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}
