Moreover, the contribution of every wind turbine on the wind power plant should be considered. Representing a large wind power plant by a single wind turbine (WT) or a few wind turbines results in a severer situation with regards to power quality. In the paper, however, a previously introduced wind power plant representation method, so called \"quasi-multiple turbine representation (QMTR) method\", is used to consider the effect of all WTs of the wind farm. It is shown that Simulink, FAST, AeroDyn, and TurbSim can be used to model the electrical, mechanical, and aerodynamic aspects of a wind power plant with 96 fixed-speed WTs. The model is used to calculate the voltage, active, and reactive powers at point of common coupling (PCC). Flicker is one of the most important power quality measures. It is induced by voltage fluctuations, which are caused by load flow changes in the grid. Modelling of an IEEE standard flickermeter in Simulink environment, instantaneous flicker sensations for two different wind power plant representations are compared. It will be shown that the QMTR method, which considers all WTs of the wind farm shows less flicker at PCC.","PeriodicalId":196861,"journal":{"name":"2007 IEEE Canada Electrical Power Conference","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131205414","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}

These indices performed well because they were primarily used for system planning as utilities then were either highly localized and regulated by the state or owned and operated by big electricity consumers. However, the situation changed drastically with the advent of unbundling, privatization/competition and power pooling in the last two decades. Consequently, incidents of power outages have become a common occurrence worldwide because of increasing load demand without proportionate increase in electrical power supply due to difficulties posed to the building of new generation centers and transmission lines by residents and environment. This paper, therefore, develops a versatile index algorithm that incorporates robust features so as to guarantee the optimal utilization of the various voltage collapse indices to adequately predict, monitor and detect the status of power system both online and off-line. It reviews existing voltage stability indices, and for the first time outlines index selection criteria to guide system operators and planners in their optimal usage to reduce outages and operational cost. The work, also, presents a new index computation scheme utilizing the complex pi-model of the medium and long transmission line. This new index will be used to effectively determine the status of power systems to prevent system overloading during power pooling and long distance wheeling of power, which has become a common phenomena among independent system operators (ISOs) and regional transmission organizations (RTOs) during peak and emergency periods. The simulation results show a favorable performance of this new index on both IEEE 14 and 30 bus systems with respect to existing indices.","PeriodicalId":196861,"journal":{"name":"2007 IEEE Canada Electrical Power Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133747021","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}
