Applying mass and energy balances along the humidifier, a mathematical model was developed and a parametric study was carried out to study the effects of the inlet Temperature and mass flow rate of the seawater and air on the system performance. According to the obtained results, as the air mass flow rate increases, so the evaporation rate of the system does to a limit determined by the transversal area of the humidifier. In addition, increasing the sea water mass flow rate favors evaporation process because the temperature differences between the fluids gets bigger, however, increasing air mass flow represents a disadvantage in the energy consumption of the unit, so this is an important design parameter.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"7 1","pages":"273-278"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78077089","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}

Two identical solar water heaters were developed in order to study their performance. One system used normal glass while the other one used special glass. Thermocouples were installed in the inlet and the outlet for each system. The two thermocouples were to record the water temperature before entering the system and the water temperature leaving the system. The temperature data for the two systems are comparatively studied. It was discovered that the system with special glass produce water with higher temperature than the system with normal glass. This suggests That the incorporation of special glass allows more heat to be gained by the system.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"98 1","pages":"524-527"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74632480","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 excitation field of the synchronous machines discussed in this paper is produced by permanent magnets, the reactive power is not controlled. To minimize the active power losses and satisfy the demand load, a two-stage approach has been proposed for the allocation and sizing of DGs in a distribution system with time-varying loads. The strategic placement of DGs can help to reduce energy losses and maintain the voltage within an acceptable boundary. The proposed method has been tested on a 9-bus test system.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"5 1","pages":"300-303"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73636768","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 predictive models can be deployed to improve the planning and operation of renewable systems and can improve the power purchase process and bring several advantages to the power utilities. The irradiance is affected by several factors, such as clouds and dust, and it becomes challenging for physical models to predict and capture the dynamics. The statistical methods are commonly used to predict the irradiance. These methods include autoregressive moving average, support vector machine, and artificial neural network. Deficiencies and challenges of existing methods include low prediction accuracy, low scalability for big data, and inability to capture long-term dependencies. In this paper, a deep recurrent neural network is used to predict the solar irradiance. Deep recurrent neural network (DRNN) is an artificial neural network with more hidden layers to improve the complexity of the model and enable the extraction of high-level features. The neural network is trained, tested, and validated using real data from the National Resources in Canada. The simulation and experimental results are compared to other methods to illustrate the advantages using the proposed approach.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"63 1","pages":"988-994"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84791097","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}

An economical energy production plan and an optimal maintenance strategy are determined in order to minimize the total cost of production, holding and maintenance by establishing a relationship between the energy production rates and the deterioration degree of the wind turbine.

Wind and solar hybrid energy have being popular ones owing to abundant, complement nature, ease of availability and convertibility to the electric energy. For hybridizing solar-wind system DC-AC or separate DC-DC converters are used one for each source. They will be connected to AD-DC or common DC-DC link to feed the loads according to the requirements. Such separate converters have the high count of elements and makes the system bulky and complex. This paper presents the performance comparison between separate cuk and buck converter and a single stage cuk-buck converter that integrates solar-wind renewable energy with battery backup using MATLAB/SIMULINK, to make best use of their operating characteristics and to achieve compactness and higher efficiency. FPGA controller is programmed for maintaining constant power at point of common coupling. An embedded controller based online state of charge estimation and battery charging system to suitably sink or source the input power based on the load demand is also carried out.
