Book excerpt: The purpose of this study was to develop an assessment of the national utility system's needs for electric transmission during the period 1995-2020 that could be met by future reduced-cost HVDC systems. The assessment was to include an economic evaluation of HVDC as a means for meeting those needs as well as a comparison with competing technologies such as ac transmission with and without Flexible AC Transmission System (FACTS) controllers. The role of force commutated dc converters was to be assumed where appropriate. The assessment begins by identifying the general needs for transmission in the U.S. in the context of a future deregulated power industry. The possible roles for direct current transmission are then postulated in terms of representative scenarios. A few of the scenarios are illustrated with the help of actual U.S. system examples. non-traditional applications as well as traditional applications such as long lines and asynchronous interconnections are discussed. The classical ''break-even distance'' concept for comparing HVDC and ac lines is used to assess the selected scenarios. The impact of reduced-cost converters is reflected in terms of the break-even distance. This report presents a comprehensive review of the functional benefits of HVDC transmission and updated cost data for both ac and dc system components. It also provides some provocative thoughts on how direct current transmission might be applied to better utilize and expand our nation's increasingly stressed transmission assets.

Book excerpt: There are two fundamental uses of high voltage direct current (HVDC) transmission: to interconnect systems where alternating current (AC) is either impractical or more expensive; or to supplement or replace AC transmission within an existing system. This paper presents some examples of successful applications of HVDC transmission and discusses methods of economic assessment of HVDC links. These include a simple comparison of alternative equipment which achieves the intended purpose, and evaluation of the payback period. The paper indicates how benefits of HVDC such as enhancement of system stability can be taken into account in the economic evaluation.

Download or read book Power Transmission Systems for Offshore Wind Farms written by Joaquin Rebled Lluch and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Several studies claim that wind power will play a major role in the energy supply of the European Union, forecasting 70 GW of new installed capacity in the next five years. Given the accelerated growth that offshore wind power is experiencing, many challenges are to be addressed in the next few years and substantial improvements are to be expected. Offshore wind farms (OWF) are expected to increase in rated power and in distance from shore, thus increasing the relevance of the transmission system. Therefore, a detailed technical-economic analysis is necessary to estimate which is the optimal transmission system to transmit the power generated at the OWF. This thesis presents a technical-economic analysis of power transmission systems for OWF. The aim of this work is to determine the most suitable power transmission technology for a given set of OWF characteristics. Costs and losses of different proposed technologies are investigated: high-voltage alternating current (HVAC), high-voltage direct current (HVDC) based on voltage-source converters (VSC), and low-frequency alternating current (LFAC). For the technical part of the analysis, the strengths and weaknesses of each technology are exposed, as well as the role of the main components investigated. Regarding the economic side of the thesis, the costs of the major components of each transmission system are associated to cost functions, and their losses modelled. Availability of the components is also considered, as well as the variability of the self-made cost functions. The self-made cost functions, being contributions of this work, are provided for public use. The costs of the whole transmission system including losses are obtained as a function of a range of variables (transmission length, rated power, voltage level, etc.). Additionally, the employed cost functions and loss calculations are summarized in a spreadsheet, which is openly available upon request. Besides giving the cost functions, the technical-economic analysis is applied to a set of case studies to draw a comparison between a range of proposed transmission systems. The obtained results indicate that the break-even point between HVAC and HVDC is to be found in the 50-100 km range, approaching 50 km in the case of large OWF (e.g. 1000 MW). Additionally, the studied cases also reveal that LFAC could result the most suitable option in the 50-70 km range.
