Smart Grids (Hardcover)

On a worldwide basis, the development of SmartGrids is a consistent answer to the problem of an efficient and sustainable delivery of electric energy through distribution grids. SmartGrids are a combination of information and communication technologies and new energy technologies. There are many different definitions of the concept of SmartGrids and thus it appears indispensable to gather the knowledge available from both industry and research laboratories in one book. Distributed generation is rightly receiving an increased amount of attention and will become an integral part of urban energy systems, providing consumers and energy providers with safe, affordable, clean, reliable, flexible and readily-accessible energy services.
The aim of this book is to describe future electricity networks that will enable all energy services to become sustainable. The traditional design of network control systems with a centralized structure is not in-line with the paradigm of the unbundled electricity system and decentralized control; this is highlighted by looking at how future active networks will efficiently link small- and medium-scale power sources with consumer demands, allowing decisions to be made on how best to operate in real time. It also looks at the level of control required: power flow assessment, voltage control and protection require cost-competitive technologies and new communication systems with more sensors and actuators than presently used, certainly in relation to the distribution systems. To manage active networks, a vision of grid computing is created that assures universal access to computing resources. An intelligent grid infrastructure gives more flexibility concerning demand and supply, providing new instruments for optimal and cost-effective grid operation at the same time.

在全球範圍內，智慧電網的發展是對通過配電網實現高效和可持續的電能傳輸的一個一致性解決方案。智慧電網是信息和通信技術與新能源技術的結合。對於智慧電網的概念有許多不同的定義，因此將來自工業和研究實驗室的知識集結在一本書中顯得不可或缺。分散式發電正受到越來越多的關注，將成為城市能源系統的一個組成部分，為消費者和能源供應商提供安全、可負擔、清潔、可靠、靈活和便捷的能源服務。

本書的目的是描述未來的電力網絡，使所有能源服務都能實現可持續性。傳統的網絡控制系統設計具有集中式結構，與解耦的電力系統和分散控制的範式不相符；通過研究未來的主動網絡如何有效地將小型和中型電源與用戶需求相連，可以看出這一點，從而可以在實時操作中做出最佳操作決策。它還關注所需的控制水平：功率流評估、電壓控制和保護需要具有成本競爭力的技術和比目前使用的配電系統更多的傳感器和執行器的新通信系統。為了管理主動網絡，創建了一個確保通用訪問計算資源的網格計算的願景。智能電網基礎設施在需求和供應方面提供了更大的靈活性，同時為最佳和具有成本效益的網絡運營提供了新的工具。
