The collected data (wind speed, temperature and pressure) used for this goal have been obtained from meteorological stations where the data have been observed during the decade 2005–2014. Technical properties of six wind turbine models were examined to evaluate the unit cost of energy in each location. The cost of energy produced shown in the results for the selected sites is in range of 0.032S/KWh to 0.0422S/KWh. Among the chosen wind turbine models, Enercon (E-58) with a rated power of 1MW appears the most competitive in terms of cost of energy for all the selected sites while In-Salah is found to be the most suitable location to produce electrical energy from wind farm among the studied sites.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126075530","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}

However, this will cause problems in some scenarios. For PV-battery systems, when the batteries are nearly fully charged, operating PV at MPP will overcharge the battery, and decrease the lifespan of batteries. Besides, it has been reported that in some sunny days, surplus power generated by PVs can cause the turmoil of the distribution power network. To address this problem, this paper proposed a modified maximum power point tracking (MPPT) algorithm with integrated active PV output power control. The proposed algorithm has been experimentally verified in an off-grid PV-battery system. According to the Power-Voltage characteristic of PV, there are two possible operating points for reduced power output, thus, a comparison of two operation points is discussed.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127378658","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}

But such high battery capacity is practically infeasible because battery forms the greatest part of the cost of the renewable power system. As an alternative solution, wind turbines can be in idle state when overall renewable power generation is high, to reduce the required battery capacity. This paper investigates the optimal operational state scheduling of wind turbines for battery capacity reduction and its effect to reduction of renewable power generation and cost. A Mixed-Integer Linear Programming problem is formulated for the scheduling. A case study shows that the decrease of renewable power generation due to idle state of wind turbines is small, even if the battery capacity becomes significantly lower.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132872201","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 characteristics of three renewable power generating systems are modeled in mathematical formulation along with its objective function to formulate a set of optimization problem. Since the state variables include integers, the mixed-integer linear programming (MILP) is an effective method to be applied to the problem. The algorithm is tested on a case study with an annual load profile that is averaged from residential and medium service customers, along with statistical data of wind and solar energy from Thailand. The MILP can obtain the complete set of optimal solutions with a single computational process. The optimal results include the number of wind turbines, the number of PV units, the volume of the upper reservoir, the rated capacity of pump motor and hydro turbine for the hydro storage system.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134326436","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}

Francis turbines are the most common turbine type in use for hydraulic power generation. A francis turbine's main components are spiral case, stay vanes, guide vanes, runner and draft tube. As the design processes of components differ with head and discharge values for each turbine, the process requires much effort and time. In recent years, Computational Fluid Dynamics (CFD) are commonly used to predict hydraulic performance of turbines since it is more economical and effective in time management. In this study, a Francis turbine is designed based on head and discharge values of an existing turbine at Kesikköprü, Ankara with an efficiency about %89 and analysed with commercial CFD codes. Pressure and velocity distributions of turbine components and turbine efficiency are examined. As a result of this study, it is obtained that there is an increment about %5 in planted turbine's efficiency. Thus, the francis turbine can generate more power with a rehabilitation process.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125605592","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}

This paper illustrates the concept by a specific implementation for global horizontal irradiance, air temperature and wind speed. We describe the model itself and the data analysis to determine the model parameters. This specific implementation and the concept is validated by designing a model from a 8 year reference dataset.

The proposed wind generation system is equipped with a Permanent Magnet Synchronous Generator (PMSG) and a Matrix Converter. Under normal operation conditions the Maximum Power Point Tracking (MPPT) is guaranteed by a speed controller that establishes the reference torque and sets the reference currents for the matrix converter. In the occurrence of voltage sags, new reference torques need to be established, to limit the currents in the matrix converter and in the PMSG stator windings. Also, to support the voltage, reactive power needs to be injected in the grid connection point. With this approach it is possible to guarantee that the PMSG is not disconnected from the grid in the presence of voltage sags with a depth of 80% all through 500ms.","PeriodicalId":287863,"journal":{"name":"2016 IEEE International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128660196","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}
