The building is a three-story located in Milan, Italy. The building was designed based on current regulations on energy efficiency in buildings. The HVAC system is designed for minimising energy consumption by the appropriate choice of the heating and cooling systems. The space heating energy is supplied by a GSHP system with vertical ground heat exchangers. The domestic hot water is produced by a solar thermal system. A major part of electricity required for lighting, domestic appliances and the functioning of GSHP system is generated through a PV system. Both the solar thermal and PV systems are installed on the building roof.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"1 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":"128515603","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}

Moreover, when the electrical load is characterised by large variations in a short time, the lifetime of conventional batteries can be seriously affected, and the maintenance costs increase accordingly. In the paper, the complete dynamic model of a sawmill supplied by a standalone photovoltaic-thermal (PV-T) power plant is developed, and the case in which the electrical storage system consists only of conventional batteries is compared with the case in which a supercapacitor bank is included. Performance and costs of both cases are discussed.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"26 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":"125098579","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}

As well known, problems in distribution systems are the main responsible of customer unavailability. In the last years, the utility interest in the improvement of the reliability in power systems is continuously growing thanks to the deregulation of the electricity market. It is known that inserting switches along the network positively affects the distribution systems reliability but, of course, it involves utility costs. This paper deals with the optimal choice of number, type and location of telecontrolled/automated circuit breakers and sectionalizers in distribution systems taking into account their cost. The optimization problem has been solved by means of a multi-objective evolutionary algorithm able to provide the minimum cost investment required to obtain a given network reliability, as well as the maximum reliability that can be achieved for a given economic investment.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"44 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":"131288572","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}

Other anomalies, related to the expected ageing, have been also observed: panels with blued cells, browed surface and others.

Finally, the described mathematical models are implemented in software that is applied to the case study of a food products company. Results indicate the future research directions as well.

Most of the proposed approaches relied so far on the use of series string of DC-DC converter to create a high voltage string connected to DCAC inverter. The boost converter is better in this application. However, under inhomogeneous irradiation, the power generated from each PV module and output DC voltage of each boost becomes unbalanced so that the output currents of each boost are balanced and equal to the string current. In this case the boost converter cannot always deliver all the power from a mixture of shaded panels and those delivering full power. In this paper, a centralized MPPT with string current diverter for solving the series connection problem in photovoltaic power generation system is proposed to overcome this problem. One important feature of the proposed circuit herein is the ability to effectively decouple each PV module from the rest of the string, making this insensitive to changes in the string current. Hence it is possible to obtain the maximum power from the PV generator and allow it to operate at the optimum efficiency. The simulation and experimental results verify that the proposed topology exhibits good performance anyway of inhomogeneous irradiation. On the other hand, the string current diverter circuit does not operate if irradiation is homogeneous. So, in this last condition, the topology efficiency is improved.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"10 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":"125126493","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 model is capable of representing terminal behavior along with internal physical variables that include temperature, potentials and ion flows. However, the model is very computational intensive and needs to be reduced for implementation into real time applications. The order reductions are carried out applying polynomial and state space approach for estimation of concentrations in electrolyte and electrodes. The potentials in the components are solved by iterative method and combined with the reduced order to substantially reduce the computational time. The two models are compared with respect to static and dynamic behavior at terminal voltage at different current rates as a function of state-of-charge (SOC) as well as concentrations of ions in electrodes and electrolyte in the cell. In addition, voltage responses of step current at charging and discharging processes are also compared.","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":"114762667","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}
