The FLL tracks the time-varying grid voltage fundamental frequency adaptively. The orthogonal waveforms of fundamental and harmonic components of grid voltage waveform are extracted using the quadrature signal generator (QSG)-SOGI and a linear Kalman filter (LKF), respectively. The fundamental voltage amplitude is obtained from the orthogonal voltage waveforms as provided by the QSG-SOGI and is fed to an extended Kalman filter (EKF) to extract the instantaneous flicker level (IFL). The proposed SOGI-FLL-KF technique provides accurate instantaneous results for PQ analysis based on the measurement of phasor quantities. Synthetically generated grid voltage waveforms are used in MATLAB/Simulink for instantaneous PQ analysis by the proposed SOGI-FLL-KF technique. The simulation results show that the proposed technique can be used as an effective technique for frequency adaptive instantaneous PQ assessment.","PeriodicalId":146438,"journal":{"name":"2012 3rd IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134243727","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}

And the configuration of the microgrid is the premise of all factors. This paper presents an optimization model to quantitatively evaluate the economic impacts of different installation sites on microgrids with multi-energy. In this model, optimal configuration schemes for microgrids installed at typical sites are designed by particle swarm optimization method. The economic performances of optimal configuration schemes are evaluated by the operation simulation with the proposed indexes. Those typical installation sites mentioned above belong to different regions which are divided into the five-level classifications in terms of the richness of wind and solar resource and the distributions of loads in China. The calculation results may be used for the decision-making references by the decision-makers.","PeriodicalId":146438,"journal":{"name":"2012 3rd IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134273232","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}

To operate in standalone mode, the Microgrid must control electricity demand or supply to maintain the frequency. The Microgrid EMS (Energy Management System) could control supply and demand with the AGC (Auto Generation Control) function using a communication line. Note, however, that the period of AGC is too slow to maintain the frequency if there is rapid variation in loads or generation. Moreover, the transition of operation mode could fail if there is too much power flow at PCC (Point of Common Coupling). In this paper, we propose a method of improving the stability of the grid-interconnected Microgrid using BESS (Battery Energy Storage System) and super capacitor. The cooperative control method between BESS and super capacitor uses droop, which is used at the generator. BESS could operate as UPC (Unit Power Control) or FFC (Feeder Flow Control) depending on Microgrid's operation strategy. We simulate the cooperative control method using PSCAD/EMTDC to verify the validity of the method. As a result, Microgrid's stability is improved using the cooperative control method, and the life span of BESS could be prolonged.","PeriodicalId":146438,"journal":{"name":"2012 3rd IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132695357","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}

Moreover, the operation of distribution system in islanded mode is still an issue due to the difference between the short circuit current in islanded mode and grid-connected mode. This paper proposed a novel adaptive protection method, measuring only the local information rather than using the communication, to adapt the protection settings to the states, such as the change of operation mode (grid-connected or islanded), the change of network topology (radial or meshed) as well as the disconnection of some DG. The directional overcurrent relays (DOCR) is adopted in the distributed system to shorten the tripping time in order to maintain the DG's connection. The relay settings are calculated offline and modified online according to the state detection, including the islanding detection, the power flow detection and the fault section detection. This protection method is verified by simulating a distribution system of Denmark in DIgSILENT PowerFactory.","PeriodicalId":146438,"journal":{"name":"2012 3rd IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133766006","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}
