Wide range of references and disturbances such as step and sinusoid forms are covered. The proposed control structure comprises a combination of state-feedback and output-feedback strategies. The output-feedback structure is selected based on the internal model principle and the whole set of gains is calculated using a modified version of linear quadratic regulator (LQR). The proposed method is particularly suited for designing linear controllers for power electronic converters. The proposed method enjoys the following advantages: the design stage is easy and algorithmic without stability concerns, and the designed loop has good robustness features. Two examples that are studied in this paper are a grid-connected three-phase, and a single-phase hybrid stand-alone renewable energy systems.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116688029","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 disturbance in power system is mainly due to sudden change of heavy load, faults, and loss of excitation. In this paper, the rate of change of transient energy of the system is taken into account i.e. the dissipation of kinetic energy (K.E.) of the power system due to disturbances as a measure of system damping. To provide additional damping in the power system without additional cost, the output power of the FACTS devices like STATCOM and SSSC already connected in the power system for compensation is used. They modulate the system output, so as to reduce the system oscillation and hence stability improves.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131108094","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 this paper, series passive compensation and shunt active compensation provided by static synchronous compensator (STATCOM) and other FACTS controllers connected at the electrical center of the transmission line are considered. The presence of series capacitors has given rise to the phenomena Subsynchronous Resonance (SSR). But in few conditions such as in fault conditions, SSR phenomenon takes place which can damage the turbine generator shaft. In this paper SSR phenomenon is studied with modified IEEE second benchmark model and various techniques has been developed for damping of SSR by adjusting the series compensation and using the FACTS controllers.
