Secondly, a model of the wind turbine, which is divided into static model and aerodynamic model, with which the angular speed of system modifies the output obtained, thus allowing the equipment to function at optimum point. Finally, an integration of each model is performed, in order to test the algorithms and prove the correct operation of each controller.","PeriodicalId":256426,"journal":{"name":"2017 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131910695","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 charger works as power factor correction and delivers a DC voltage to the battery. To this, a bridgeless boost topology is used, this and the battery are modeled and then, an adaptive control strategy is developed. This have into account the battery changes to tune the controller and keep sinusoidal the input current and keep it in phase with the main. Furthermore, the output voltage is controlled to a constant value with a suitable ripple to charge the battery. The outcomes of the simulation of this development are presented, where the average total harmonic distortion and power factor were 4.78 % and 0.9877 respectively.

The use of Doubly Fed Induction Generator into wind farm cause a distortion of the waveforms of voltage and current. The percentage of harmonic distortion is greater if the number of wind turbines is large. If the simulation model are not defined properly, the harmonic distortion result would be incorrect. For power quality studies, it is required that the model represent the wind turbine in a detail form. However, when the wind farm has a high power capacity, a detail simulation model exceed the computational capacity of the software. As an alternative solution, aggregation methodologies of wind turbines are considered. To determine the precision of the simulation, an analysis of detail and aggregate model is being made based on IEC Std. 61400-21: Measurement and assessment of power quality characteristics of grid connected wind turbines. The comparison shows that an aggregate model could represent properly the behavior of large-scale wind farm for power quality studies.","PeriodicalId":256426,"journal":{"name":"2017 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129297867","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}

If the energy provided by the panel is not enough to satisfy the demands, the system becomes dependent exclusively of the grid. This constraint demands the use of a battery bank, therefore it is necessary to add a third port to the micro-inverter to connect this energy backup. In this paper, a two stage micro-inverter is proposed, the first stage is a DC/DC Triple Active Bridge (TAB) converter that integrates a back-up battery and works in soft switching; and the second stage is a Voltage Source Inverter (VSl) that operates in both grid-connected mode (GCM) and Stand Alone Mode (SAM). The grid-multimode operation controller developed detects the islanding fault and maintains the energy quality for a typical nonlinear load. Reliability and robustness of Uninterrupted Power Supplies (UPS) are increased by the proposed control.","PeriodicalId":256426,"journal":{"name":"2017 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115481221","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 optimization problem formulation developed in this work has the objective of mitigating undervoltage violations in the circuit using the minimum number of SVCs while improving the traditional voltage regulation device operations and circuit losses. Undervoltage area criterion is used to identify effective candidate locations and the binary particle swarm optimization (BPSO) algorithm with quasi-static time series (QSTS) simulations are used to determine the optimal SVC locations. The results show that the proposed method is effective in identifying the optimal SVC locations in large distribution circuits.","PeriodicalId":256426,"journal":{"name":"2017 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122775644","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, the automotive communication protocols present two problems: 1. the connections between devices are very complex and their maintenance is difficult, and 2. most of the commercial devices, specialized to send data between devices, use proprietary software to perform operations inside the vehicle. In this work, a novel embedded platform was designed to measure and control the speed and torque of electric motors of a 200 kW electric vehicle. It is a versatile, modular and open-source design, which exchanges data with each motor using the CAN Bus protocol to control their speed. Also, the implementation and maintenance of the proposed platform becomes simpler.

This converter has been chosen due to the autonomy of each full bridge. Other advantage is the feasibility of handling the power by cell when there are changes in the batteries state of charge (SOC). In order to take advantage of these benefits, a control strategy has been developed. The main goal of the proposed solution is to change the power produced by each inverter in function of SOC, guaranteeing a proper regulation of the overall power, without affecting the parameters of quality of the output voltage like harmonic distortion and amplitude. The designed solution was tested by power sources variations, finding the control strategy appropriate to accomplish the objective, to modify the power produced by each full bridge in function of SOC without changing overall power of the system and keeping the output voltage constant.","PeriodicalId":256426,"journal":{"name":"2017 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130226053","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}
