The aerodynamic model converts the kinetic power of the wind into a mechanical power illustrated in a rotational speed of the rotor and transmitted to the generator by a rigid shaft of one degree of freedom, it's the model of a gearless one masse drive train connected to the PMSG to produce electrical power. The PMSG is then controlled to produce maximum electromagnetic torque with minimum stator current by applying the Zero d-Axis current control and the optimal torque control allows us to obtain the maximum mechanical power from the wind turbine.

The individual converters in a distributed power system are usually designed for general usage and their controllers are synthesized to provide a suitable transient response in stand-alone operation. Often, a tight regulation is required for the output voltage of both the source and the load converters. Tightly regulated power electronic load converters sink constant power from the intermediate bus and show a strong nonlinear voltage-current characteristic that can be approximated by a static constant power load (CPL) when connected to the output of the source converter. At the slow time-scale, CPLs exhibit negative impedance behavior making interconnected converters prone to a high risk of instability and therefore the mitigation of this problem is an important issue in the multiple-stage switched mode power supply design. In this paper, a discussion on the validity of the CPL approximation is presented and then a sliding-mode approach is used to stabilize a source boost converter feeding a regulated buck converter. The resulting sliding-regime for linear switching surfaces in both the source and the load converters is analyzed and the conditions for the existence of sliding-mode are derived. A study of the system is performed in terms of the converter start-up with the limitation of the inrush current and the output voltage regulation in presence of external perturbations. PSIM simulations are in perfect agreement with the theoretical predictions.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114759228","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 connection uses an adaptation stage acting as an interface between the GPV and the load. The adaptation stage is usually composed of a DC-DC converter monitored by a controller of the maximum power point MPPT (maximum power point tracking). The aim of this work is to realize a study and comparison between two methods of MPPT: the Incremental conductance (Inc-cond) method and the perturbation & observation method (P & O). For this we devoted a part of the work to the study of the components constituting the global photovoltaic system namely: the photovoltaic module, the DC-DC converter, and the MPPT controller. The second step is reserved to comparison between MPPT methods-both designed in the MATLAB / SIMULINK environment-performed by simulation. The comparison results demonstrated good performance of the Incremental Conductance method compared to the Perturbe & Observe method.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125955557","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}

Cantilevers are of various types; this classification is based on the connection of its both ends if it is connected from its one end while the other end is free to move then this type of cantilever is named as fixed-free cantilever. On the other hand if both ends are fixed then it is called fixed-fixed type of cantilevers. Numerous high resonant modes of cantilevers and its application in the field of science have been analyzed. An introduction to quantum dot concept and its incorporation to the cantilever have been shown and various applications of this technique are analyzed. A detailed overview of the fabrication process of the cantilever is discussed in this report. Fabrication of the micro and nano cantilevers has been discussed. The introduction to the quality factor of a cantilever is discussed to analyze the performance of a particular cantilever, a formula of quality factor has been shown and the effect of quality factor on the efficiency and rate of energy dissipation in a cantilever is analyzed.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128914550","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}

Multilevel converters are considered today among the most suitable topologies for DPGS connected medium voltage grids.

In this paper, this control method is applied on a grid-tied three-phase three-level neutral point clamped (NPC) inverter. The main objectives behind the proposed method are: performs a perfecto control of the powers exchanged with the grid active and reactive powers in steady state operation, and avoid the overcurrent due to the grid faults. The effectiveness of the proposed FSC-MPC applied on the NPC converter is validated with numerical simulations and experimental tests.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128972728","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}

A control is conceived to manage power flows. Priority is given to PVG as it satisñes the load requirements. To balance the power a FCG is used when the power provided by PVG is not enough. The storage device is used to store the enough of power produced by PVG. The charge discharge process is optimized. The voltage regulation at the point of common coupling is an important issue in the connection of power PVG to the FCG and the storage devices interconnections. A fizzy supervisor is developed.

The first part of the paper is devoted to the description of the electromagnetic inverse method in the time domain and its resolution with an optimization method based on genetic algorithms. Subsequently, and to test the proposed method with respect to near-field measurement errors, we propose to validate the time domain inverse method with an experimental model. To validate our approach, we will present and compare the measured field cartography with the calculated field cartography by using the parameters of the estimated model.
