Conventional D-STATCOM is a compensator-based power electronic device, employed as a reactive power source in AC power systems to maintain voltage stability. However, these devices have a limited ability to mitigate voltage fluctuations caused by active power disturbances. To fully exploit the potential of the D-STATCOM device, energy storage technology has been combined with D-STATCOM to support the grid with reactive and active power in the microgrid. The proposed approach employs the advantage of high-power storage unit (supercapacitor) and high energy storage unit (battery) with a D-STATCOM configuration to avoid the limitations of using only one specific storage unit. Furthermore, the fuzzy logic management approach distributes the power required almost instantaneously between the energy sources. Thus, it is possible to implement an intelligent real-time energy management controller able to effectively distribute the required current from the HESS and provide good performance of the voltage at the PCC. Verification of the control designs has been achieved through simulation using MATLAB/SIMULINK based on the derived analytical model in state-space form. Comprehensive simulation results show that the modified D-STATCOM topology-based HESS with a proposed fuzzy controller demonstrates significant improvements over conventional D-STATCOM controllers in supporting voltage stability under different conditions in distribution networks.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128497911","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}

When the signum function is replaced with an approximating one, the estimation error will not go to zero anymore, but it will go to the bounded region around the origin. In this paper, the bounded region is obtained and controlled by adjusting the parameters of the proposed observer. The DC motor system suffers from a perturbation vector, and unmeasured angular acceleration is utilized as an application to a nonlinear controller based on the proposed observer.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129769887","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 order to achieve the Maximum Power Point Tracking (MPPT), a method for wind turbine operations regions 2 and 3 has been developed here based on Extremum Seeking Control (ESC) approach. The reference speed to the generator and the reference pitch angle to pitch control were generated via dither-modulation ESC scheme. In addition to using ESC for generating the desired reference trajectories, ESC is also used for tuning PI controllers in order to determine the optimal gain values that can achieve a better tracking. The purpose is to (i) ensure the stability of the system (ii) extract the maximum electrical power capture as well as reduce the mechanical loads to protect the turbine. Comparison between the performance of the system using ESC real-time optimization and Particle Swarm Optimization (PSO) has been carried out in this paper.

Copyright protection is a vital issue to prove the ownership of products in these networks. Consequently, digital watermarking that hide invisible watermark or logo plays a significant role in overcoming copyright issue. However, any person has access to multimedia products can simply use these products. Also, there are professional attackers can remove the watermark or logo without loss the visibility of the multimedia product and claim their ownership for the digital products. This study proposes an image watermarking model that only allows authorized users to use the watermarked image. This model is robust against crop and rotation attacks. It is based on the proposed embedding method that we named a \"concentric rectangles\", which embeds data in rectangles starting from the center toward outer boundary to overcome the crop and rotation attacks. The resulted watermarked image is distorted in such a way to be recognized by any user, but only the authorized one can obtain a high quality of the watermarked image. The experimental results of the proposed model show that the embedding capacity can reach up to 25% from the size of the host image with watermarked image quality above 40 dB in terms of peak signal to noise rotation (PSNR). Furthermore, the proposed model is fully retrieval for the watermark image (logo) and the logo still retrieved a with a recognized vision until 10 dB of signal to noise ratio of noise adding.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122406827","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}
