The increasing phase-out of fossil fuel based conventional power plants leads to new challenges on how to operate future power grids. To support research efforts towards meeting the upcoming challenges a new laboratory will be founded with the main objective of establishing novel and innovative investigation opportunities for application-oriented wind energy research and close cooperation with industry and academia. The infrastructure will include a laboratory-scale modularly reconfigurable wind farm and feature high-performance control systems for accurate real-time emulation of aerodynamics as well as wind farm energy management. This paper presents the proposed concept, discusses present demands and requirements as well as points out future research capabilities by means of simulation results.","PeriodicalId":6701,"journal":{"name":"2019 IEEE International Conference on Industrial Technology (ICIT)","volume":"221 1","pages":"697-703"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73185414","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}

Predictive control is an advanced control strategy that is implemented for control of multi-level converters due to many advantages of fast response, no need proportional gain and easy to implement. To achieve these results, this paper proposes a predictive current control technique for a single-phase reduced multi-level grid-connected converter. The proposed reduced converter is a general topology for cascaded multilevel converters that reduce the number of components and generates high number of levels than traditional multi-level configurations. The proposed topology is connected to a grid and model predictive control technique is applied to control of the grid current. The model predictive control is used in two cases for the proposed 15-level reduced converter and proposed 31-level cascaded multi-level converter. Finally, to validate of the proposed reduced multi-level converter and proposed model predictive control the simulation results are presented under MATLAB/Simulink platform for proposed both converters.","PeriodicalId":6701,"journal":{"name":"2019 IEEE International Conference on Industrial Technology (ICIT)","volume":"1 1","pages":"1790-1795"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77106122","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}

Furthermore, heavy magnetic saturation largely rotates saliency position in the direction of the current vector and thus destabilizes the sensorless control. The proposed method achieves stable sensorless control in extensive heavy load states by using information of magnetic saturation. In consequence, the proposed method doubles the torque range for sensorless control of the test SynRM, and achieves stable position sensorless control in all torque ranges.","PeriodicalId":6701,"journal":{"name":"2019 IEEE International Conference on Industrial Technology (ICIT)","volume":"38 1","pages":"255-260"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78109869","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 proposed SPS-MPC strategy achieves a fixed switching frequency, which is beneficial regarding of semiconductor loss distribution, and also to ensure that a high-bandwidth is achieved that compares favorably to the finite-control-set MPC case.

During the process of drawing, different components of the portrait can be distinguished such as hair or eyes by strokes. Besides, sketch pattern is added to line drawing model using cluster algorithm and presents a unique style.

On the Traveling Salesman Problem (TSP) we measured the influence of hybridization a 2-opt heuristic-based local searcher into the evolutionary algorithm. Evolutionary Algorithm gives a diversification, while 2-opt improves intensification. The TSP is nowadays already solved for small instances rather efficiently by exact algorithms (e.g concorde) and by local search heuristics as LKH by Helsgaun. Nevertheless, the paper shows statistical analysis that intelligently hybridized algorithm combines good qualities from the both applied components and outperforms each individual method and suggest what level and type of hybridization is best for a given problem to make them intelligent. In tests we applied hybridization at various percentages (level) of evolutionary algorithm iterations. The main contribution of the paper is to show statistical analysis of hybridized evolutionary algorithms. For that purpose we used well known statistical tools. Since the evaluation scores were not normally distributed, the nonparametric Kruskal-Wallis Test (KWT) was used instead of the standard one-way ANOVA. The differences were considered to be statistically significant in cases where the estimated p-values of statistical tests were less than or equal to 0.05. The analysis with KWT showed that there exist statistically significant differences in place of hybridization. The analysis revealed significant differences in all levels of the hybridization. However, intensifying the level of hybridization further increased the p-value of the KWT, which means that the place of hybridization becomes of a less importance when the level of hybridization increases.","PeriodicalId":6701,"journal":{"name":"2019 IEEE International Conference on Industrial Technology (ICIT)","volume":"21 1","pages":"899-904"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79934370","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}
