Book excerpt: Rating of Electric Power Cables in Unfavorable Thermal Environment is the first text to provide you with the computational tools and techniques needed to successfully design and install power cables in areas affected by such factors as outside heat sources, ground moisture, or impediments to heat dissipation. After thoroughly reviewing standard rating models, the author discusses several new techniques designed to improve cable ampacity, as well as new computational techniques for analysis of cyclic loads. To facilitate computational tasks he utilizes six representational model cables throughout the book, including transmission-class, high-voltage, distribution, and bundled types. End-of-chapter summaries, liberal numerical examples, and practical, real world applications make this text a valuable resource for making better design and operation decisions.

Download or read book A New Swing-Contract Design for Wholesale Power Markets written by and published by John Wiley & Sons. This book was released on 2020-12-30 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides comprehensive information on swing contracts for flexible reserve provision in wholesale power markets This book promotes a linked swing-contract market design for centrally-managed wholesale power markets to facilitate increased reliance on renewable energy resources and demand-side participation. The proposed swing contracts are firm or option two-part pricing contracts permitting resources to offer the future availability of dispatchable power paths (reserve) with broad types of flexibility in their power attributes. A New Swing-Contract Design for Wholesale Power Markets begins with a brief introduction to the subject, followed by two chapters that cover: general goals for wholesale power market design; history, operations, and conceptual concerns for current U.S. RTO/ISO-managed wholesale power markets; and the relationship of the present study to previous swing-contract research. The next eight chapters cover: a general swing-contract formulation for centrally-managed wholesale power markets; illustrative swing-contract reserve offers; inclusion of reserve offers with price swing; inclusion of price-sensitive reserve bids; and extension to a linked collection of swing-contract markets. Operations in current U.S. RTO/ISO-managed markets are reviewed in the following four chapters, and conceptual and practical advantages of the linked swing-contract market design are carefully considered. The book concludes with an examination of two key issues: How might current U.S. RTO/ISO-managed markets transition gradually to a swing-contract form? And how might independent distribution system operators, functioning as linkage entities at transmission and distribution system interfaces, make use of swing contracts to facilitate their participation in wholesale power markets as providers of ancillary services harnessed from distribution-side resources? In summary, this title: Addresses problems with current wholesale electric power markets by developing a new swing-contract market design from concept to practical implementation Provides introductory chapters that explain the general principles motivating the new market design, hence why a new approach is required Develops a new type of swing contract suitable for wholesale power markets with increasing reliance on renewable energy and active demand-side participation A New Swing-Contract Design for Wholesale Power Markets is an ideal book for electric power system professionals and for students specializing in electric power systems.
