The main interest was to study the dynamic behavior of power system in view of major incidents and vital scenarios such as transient stability and frequency stability. In addition, the design of a robust control strategies like the Automatic Generation Control (AGC) and the Under Frequency Load Shedding (UFLS) was envisaged. An application on the IEEE 10 bus test system and on the islanded 57 bus Algerian grid called Pole InSalah-Adrar-Timimoun (PIAT) was performed. The dynamic modeling was carried out using the EUROSTAG Macro-Block tool. A series of events such as three-phase short circuit and load variation were presented during the simulation. The main attention in this work was the modeling and the simulation of alternating fast and slow phenomena such as the rotor oscillations and the centralized control for enhancing power system operation and control.","PeriodicalId":112293,"journal":{"name":"2019 Algerian Large Electrical Network Conference (CAGRE)","volume":"374 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122346363","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 an acceptable attenuation of current harmonics in grid tied inverters and meet grid interconnection recommendations, an inductor-capacitor-inductor (LCL) type filter is commonly used as an interface between the inverter and the grid. However, this filter exhibits a resonant peak that should be properly damped to ensure system stability. Moreover, grid impedance variations, mainly under weak grid conditions, may shift the resonance frequency which compromises the controller design. This paper proposes a systematic approach to actively damp the LCL filter resonance using the notch filter-based control. An adaptive approach is also considered to improve the control performance under grid impedance variations. Computer simulations results are presented to demonstrate the effectiveness and robustness of the proposed control method.","PeriodicalId":112293,"journal":{"name":"2019 Algerian Large Electrical Network Conference (CAGRE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130805359","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}

Where, power electronics switching frequency may generate a large amount of harmonics. Thus, this work assesses a single-phase inverter control’s based on the Direct Power Control (DPC). The grid synchronization technique has been performed based on Quadrature Signal Generator (QSC) and a Frequency Looked Loop (FLL) with FLL gain normalization owing to its capability to enhance the generated orthogonal voltages and to estimate the grid frequency. Moreover, the DC voltage is maintained stable trough a DC voltage regulator. To improve the generated power quality, Particle Swarm Optimization (PSO) based PID is performed and compared to PSO based PI. To investigate the DPC’s performances, a simulation of the overall system is performed and presented along with harmonics spectrum analysis of the voltage and the injected current.","PeriodicalId":112293,"journal":{"name":"2019 Algerian Large Electrical Network Conference (CAGRE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123162464","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 obtained results were shown that the induction caused by the high voltage power lines (HVPTL) affects the electrochemical character of the buried pipeline and accelerate their corrosion.
