Nowadays the need for larger power converter-based generation plants increases continuously, and LCL+trap filter arises as a solution when switching frequency is reduced due to the power increase. However, the tuning of current controllers becomes more complex as the LCL+trap filter lead to a considerably high order system. In this work a method for tuning the gains of proportional resonant current controllers for three-phase high power converters linked to the grid through a LCL+trap filter is proposed and analyzed. Simulation and experimental results taken in different cases are shown to validate the proposed method.","PeriodicalId":243870,"journal":{"name":"2014 International Conference on Renewable Energy Research and Application (ICRERA)","volume":"100 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":"133570260","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 predicted values were found to be in very good agreement with the experimental values with mean relative error less than 0.18% and 3.26% for the preheat tank stratification temperatures and the solar fractions, respectively.

To supply power to the AC mains network, costly and inefficient power invertors/convertors setups are used. But ultimately, the generated power from such renewable energy sources may deliver to a DC load. A possible solution that can omit the usage of costly and inefficient power invertors/convertor setups is to install a DC network linking the DC devices to DC power supplies. This paper is to develop concepts and an outline of DC nano-network for a Smart Home, composed of: a home area network with a Smart Meter and Intelligent Devices. The Smart Meter and Intelligent Devices manage and control the loads by group using different wireless nodes. Efficient algorithms will be developed to manage loads during peak hours, to coordinate between the Smart Meters and Intelligent Devices and to monitor the power flow. The total load of the building will be categorized and managed. Intelligent Devices are attached to each load, monitoring and controlling the power flow individually. These Intelligent Devices can communicate with the Smart Meter and based on the decision making algorithms, the load can be managed during peak hours.","PeriodicalId":243870,"journal":{"name":"2014 International Conference on Renewable Energy Research and Application (ICRERA)","volume":"21 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":"131682112","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 our previous report, it was shown that the power generation of an FPM, which is designed with multiple stages that mimic natural leaf arrangements, exceeds that of a conventional planar PV module. It was also shown that shadows cast by the FPM's upper-stage cells significantly influence the output power of the lower-stage (second stage) cells. In this paper, we show that the power generation of each cell depends on its size and shape, and that the output power of an FPM with square cells is larger than one with sector cells.

The proposed method, utilizing the linear relationship between the solar irradiation and the maximum power point current, directly provides the maximum power point current and hence the maximum power points trajectory. Therefore it does not require utilization of any search algorithm. Also it has been investigated that the maximum power point current is almost independent of the solar module temperature. Due to this interesting behavior, the proposed method has also superior response for the solar modules working under large temperature ranges. Therefore it has significant advantage over the conventional indirect methods using short circuit current or open circuit voltage. The proposed method is implemented on a boost type converter in MATLAB simulation environment and showed better results in terms of stability and power harvested from the solar module. The method is suitable for the solar systems such as used with micro-inverters.","PeriodicalId":243870,"journal":{"name":"2014 International Conference on Renewable Energy Research and Application (ICRERA)","volume":"7 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":"128816898","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}
