In the present, we are interested in harnessing marine energy currents, especially the hydro-kinetic turbines with horizontal axis. The density of water is 832 times greater than air one and underwater currents are also more powerful than the wind, the electric power supplied by a hydroelectric turbine is much greater than that provided by a wind turbine. In this fact water turbines are smaller than wind turbines. The aim of the present work is to calculate the hydrodynamic loads, estimate the energetic performance and determine the blade optimal parameters for a turbine. The motion of the rotor produces a three dimensional flow, which make the modeling task complicated. Two hydrodynamic theories are combined “Blade Element Method” and “the axial momentum theory” in order to find all essential parameters for sizing blades. The equations obtained are solved by using an iterative algorithm in order to obtain the hydrodynamic loads and torque. Computations were accomplished for a NACA4415 profile.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"37 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":"123634167","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}

Obtained results show that polymer mirrors present more soiling deposition than glass solar mirrors at same exposure conditions. In addition, it was shown that both tested types present a variation of soiling rate with the climatic season on the site. It was also relieved that the soiling rate is function of the variation of the wind speed and the relative humidity during the exposure.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","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":"129707107","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}

These concentrators are used as a secondary optical element in both cases with and without a Fresnel lens as a primary stage. Results show that the optical efficiency is almost equal for the two concentrators if used alone, and obviously decreases when a primary stage is added. Regarding the size of the elements we found that the length, the input radius and the concentration ratio of DTRIC increase with the increment of the acceptance angle, however, the length, the input radius and the concentration ratio of CPC decrease. Also we notice that the two lengths are equal in the angle 48°, and the input radius and the concentration ratio are equal in the acceptance angle 30°.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"68 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":"121123761","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 conversion structure has a twofold requirement that consists in ensuring that the current injected to both load and grid obeys to the grid connection standards and sets the DC bus voltage similar to the reference voltage given by the MPPT algorithm. The advanced functions that can be added to the grid connected inverter are compensation for reactive power requirements and the cancelation of the harmonics created by the nonlinear loads connected to the point of common coupling (PCC). Different scenarios of condition climate and load profile have been considered as a reference to define exemplary realistic power control schemes, to quantify through load flow simulation analysis the capability required to the PV inverters in order to follow the desired control function.

The considered aero-generator involves a hybrid excitation synchronous generator (HESG). To operate at constant-power, it is recommended to use a feedback flux-weakening control, the hybrid excitation circuit is compatible with the extended-speed-range constant-power operation, the flux-weakening and the anti-windup controls that can be achieved simultaneously. In addition to this, an optimization of the electromagnetic torque is provided to improve the HESG efficiency. However, these controls require the measure of wind speed, rotor flux, rotor speed and aerodynamic torque, which are all difficult in practice and not very reliable. This paper presents a design of sensorless flux-weakening power controller. For the achievement of the above energetic goal without resorting to mechanical sensors, a control observation strategy is developed, based on the nonlinear model of the whole controlled system using only electrical variables measurements. The effectiveness of the proposed regulator is analyzed using tools from the Lyapunov stability. These theoretical results are proved by a series of simulations to show the contribution of hybrid excitation at a high wind speed.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"77 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":"128122837","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}
