{"title":"The electrical coupling effect on the behavior of the load flow solutions for voltage collapse purposes","authors":"R. Guedes, L. Alberto, N. Bretas","doi":"10.1109/PES.2004.1373194","DOIUrl":"https://doi.org/10.1109/PES.2004.1373194","url":null,"abstract":"This work analyzes the electrical coupling effect on the behavior of the load flow solutions for electrical power systems. Due to the nonlinarities, the load flow equations does not have a unique solution. The normal power system operating point corresponds to the high voltage solution (HVS) of the load flow equations. There is also a set of load flow solutions that present a low voltage level at one or more load buses. These are called the low voltage solutions (LVS). The number of LVS that may exist depends, basically, of dimensions of the power system as well as of its load level. There is a common agreement that the number of LVS decreases as the system is loaded, in such a way that at the voltage collapse point neighborhood, there is only one remaining LVS. In case the load continues to increase, the high voltage solution bifurcates with this last LVS, producing the voltage collapse. This work shows that the existence of a single LVS at the collapse neighborhood may not be always true. It is shown that the existence of weakly coupled buses may cause the existence of more than one LVS at the collapse point neighborhood. The effects of the electrical coupling are initially analyzed for a simple 3-bus test system. As the coupling between the two load buses is reduced, the load flow solutions tends to bifurcate at the same time. Moreover, it is proven for that 3-bus test system, that all the load flow solutions must bifurcate at the same time, if the two load buses are totally uncoupled. Finally, the paper presents some simulations with the 118 buses, showing the existence of more than just one LVS at the voltage collapse neighborhood.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128120861","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}

Superconductor technologies offer solutions to critical problems facing the power transmission and distribution grid today and will play a major role in the smart and high capacity grid of the future. The best known of these technologies is superconductor underground power transmission cable. By virtue of its high current density and low losses, it offers high power capacity, avoiding higher transmission voltage levels, with minimal local environmental impact, either thermal or electromagnetic, which enables installation in the midst of a dense underground network of services typical of urban environments. Particularly cost-effective will be retrofit installations through existing conduits, avoiding the digging up of city streets. Less well known is the low inductive impedance of the shielded dielectric superconducting cables, which can relieve an entire overloaded network and enable AC current control through the use of a phase angle regulator. A variety of precommercial demonstrations are underway around the globe. SuperVAR(tm) dynamic synchronous condensers, rotating machines based on high temperature superconductor rotor coils are another key technology for the future grid, the first of which is already in a beta site today. These machines provide a high level of reactive compensation on short time scales, by virtue of their remarkably low synchronous reactance which stems from their compact and iron-free design. Typically packaged in containers, these compact condensers can be conveniently sited at substations or directly at load or generation sites throughout the grid and will have a major impact in stabilizing the grid against voltage instability and outage. They complement advanced power electronic solutions which are already being sold commercially. Superconductor fault current limiters are another key technology which addresses the critical problem of ever rising fault current levels in ever growing urban environments. This equipment exploits the superconductor transition to the normal resistive state above a critical current. Prospects for commercial application of this technology are enhanced by progress in commercializing advanced higher temperature superconductor wire.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126793238","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 South African power pool (SAPP), West African power pool (WAPP) and the initiatives in North Africa with interconnections to the middle east represent vast knowledge domains. These domains range from economic to cultural to historical. Modeling the intent therefore of these initiatives (i.e. a given power plant, series of plants or development projects in a given system) generates technical and societal 'impact' data across academia, industry and other layers of society. Several studies are sited to illustrate the growing importance of 'knowledge management' versus 'knowledge transfer' and the resulting possibilities. In turn the principal studies on African interconnections are sited as foundation candidates toward building these knowledge bases. References from contemporary events such as the Californian energy crisis and projects such as the three Gorges project in China and the Brazilian Hydro experience are also sited for their own internal knowledge experience.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124926781","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}

This presentation discusses the TransAmerica Generation Grid (TAGG) Project (Transmission Component), a new high-voltage direct current (HVDC) transmission line project that would interconnect Arizona, California, Illinois, the Dakotas, Texas, and the states in between to provide a major new conduit for electricity on a national scale. It is proposed that this approximately $11 billion endeavor be initially financed by the federal government as a Government Sponsored Enterprise (GSE) and subsequent to its construction and becoming operational, would be privatized and operated and managed as a private federally chartered corporation-as is the case with the Federal Home Loan Mortgage Corporation (Freddie Mac), the Federal National Mortgage Corporation (Fannie Mae) and other GSEs. The TAGG project has evolved from discussions within the electrical transmission and utility industries, the coal and wind power industries and among state officials in the West and upper Midwest over the last 15 years. It addresses three major concerns that are currently facing the U.S. power industry: (1) It provides a means to tap the tremendous coal and wind power resources of the Dakotas, Colorado and Wyoming for use by the rest of the country and allows the diversification of wind generated power across a large section of the US; (2) It relieves transmission constraints that exist in the southwest and between the upper Midwest and Texas; and (3) It enhances the deregulation of the U.S. power industry by providing existing generation with better access to new markets.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124776436","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}
