The most important elements in such systems are photovoltaic cells that are connected as an array to produce usable electric energy. These systems need electronic converters to convert the system's output current and voltage into a proper form when considering the conditions of the system's load and its needs. The most commonly used electronic converter is the DC to DC converter where high voltage is generated from the low solar cell voltage. This paper, explores the PV system and DC to DC converter with reference to two cases: in the first case, the system was designed as a closed loop system, since the situation of the system depends on the algorithm of the maximum power point tracking (MPPT), which captures the maximum amount of sunshine to generate the maximum electrical power. This system simulation and hardware implementation was done using the MATLAB/SIMULINK software program and real components integration. In the second case, the system was designed depending on MPPT, but the simulation was done by using a fuzzy logic controller. The implementation and simulation results for both cases are presented to illustrate the output voltage's steady state returning ability when the input voltage influence varied. The presence of a minute settling time and over-shoot in output voltage return ia apparent as well. Finally, the result for the two cases is compared to ascertain which case is better.","PeriodicalId":243870,"journal":{"name":"2014 International Conference on Renewable Energy Research and Application (ICRERA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121676085","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}

Since the nature of the some renewable energy resources (RES) such as solar and wind energy is intermittent, the reliability of the system supplied from those sources is low. A hybrid energy system combining the several RES is one of the viable solutions to increase the reliability of the system. This paper develops a optimal sizing method for hybrid energy systems incorporating photovoltaic (PV), wind and battery components. In the developed model, the effects of variations in air density and PV conversion efficiency on the generated energy amount are considered in the calculation resulting in more accurate optimal sizing. A remote area in Texas State, USA, is chosen for optimal sizing of hybrid PV/wind/battery energy system based on the case study. Meteorological data such as solar radiation, wind speed and ambient temperature is modified and then converted to useful energy. In order to avoid using excessive battery capacity, the demand response technique is applied for the situation in which energy demand is much more than energy generation. The results show that assuming air density and PV conversion efficiency to be constant causes about 15% and %20 deviation in calculation, respectively. The demand response method also provide saving of 28% in capital cost.","PeriodicalId":243870,"journal":{"name":"2014 International Conference on Renewable Energy Research and Application (ICRERA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123407404","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}

Aside from this energy service challenges the rural population also struggles with unsafe drinking water in terms of widespread arsenic contamination of well water. Access to electricity, clean cooking gas, and safe drinking water services are genuine needs of the rural poor and are essential to improving welfare. These needs can be addressed individually or using an integrated approach. This study considers a holistic approach towards tackling both of these issues via integrated renewable energy-based polygeneration employed at the community level. The polygeneration unit under consideration provides electricity via a pV array and cow dung-fed digester, which in turn is coupled to a gas engine. Excess digester gas is employed for cooking and lighting, while waste heat from the process drives a membrane distillation unit for water purification. The system is sized to serve a community of 52 households (Pani Para, Faridpur District) with 14 kWe peak demand and 250 kWh/day primary electricity loads. Technical assessments and optimization have been conducted with HOMER. Results show that electricity demand can be met with such a system while simultaneously providing 0.4 m3 cooking fuel and 2-3 L pure drinking water per person per day. Cost estimates indicate that this approach is highly favorable to other renewable options.","PeriodicalId":243870,"journal":{"name":"2014 International Conference on Renewable Energy Research and Application (ICRERA)","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115496698","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}

In this paper, a new reconfiguration method based on neural network is proposed for PV arrays under partial shadow conditions. A new connection control algorithm based on artificial neural network is presented by the proposed method. This method includes fixed part and adaptive part and uses short circuit currents of PV panel group in every rows of adaptive and fixed part in array. A neural network used for reconfiguration strategy finds new configuration scheme of PV array. Then, adaptive parts are connected to rows of fixed part according to this configuration with switching matrix. Proposed approach has been verified with experimental results obtained using Beagle Board XM microprocessor board in real time for 3×4 array. As shown in results, many contributions such as an improvement in the output power of the PV array, an efficient reconfiguration strategy, real-time applicability, easy measurable parameters, and independence from panel types have been obtained with proposed method.","PeriodicalId":243870,"journal":{"name":"2014 International Conference on Renewable Energy Research and Application (ICRERA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125379011","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}
