Book Description :

Electric power transmission relies on AC and DC grids. The extensive integration of conventional and nonconventional energy sources and power converters into power grids has resulted in a demand for high voltage (HV), extra-high voltage (EHV), and ultra-high voltage (UHV) AC/DC transmission grids in modern power systems. To ensure the security, adequacy, and reliable operation of power systems, the practical aspects of interconnecting HV, EHV, and UHV AC/DC grids into the electric power systems, along with their economic and environmental impacts, should be considered. The stability analysis for the planning and operation of HV, EHV, and UHV AC/DC grids in power systems is regarded as another key issue in modern power systems. Moreover, interactions between power converters and other power electronics devices (e.g., FACTS devices) installed on the network are other aspects of power systems that must be addressed. This Special Issue aims to investigate the integration of HV, EHV, and UHV AC/DC grids into modern power systems by analyzing their control, operation, protection, dynamics, planning, reliability, and security, along with considering power quality improvement, market operations, power conversion, cybersecurity, supervisory and monitoring, diagnostics, and prognostics systems.

Book Description :

Electricity is a basic requirement for a modern economy, and transmission grids at the center of transition to a low-carbon power system. They are the principal means to integrate large shares of wind and solar power and they are essential to ensuring a secure and reliable electricity supply. Grid companies around the world are struggling to find their niche in this transition. The State Grid Corporation of China (SGCC) is one of the principal players in this round of global competition. Central state-owned enterprise (SOEs), such as SGCC, continue to hold the 'commanding heights' of the Chinese economy. Their relationship with the Party-state is crucial to understanding the questions of whether SOEs take orders from, and do the bidding of, the Chinese Communist Party, and how they operate under the state ownership and with a wide range of operational autonomy and expectation that they are profit-maximazing corporations. This book examines the origin, development and expansion of SGCC, the world's largest utility company and the 7th largest corporation. By telling both the electricity story and the SOE story, it provides insights into the challenges facing the grids and their possible futures. It challenges the orthodox account of Chinese politics that portrays SOEs as little more than puppets, jumping to every demand of the Party-state. It shows that SGCC has been built into a modern corporation by entrepreneurial managers. By extending its operation to four continents, SGCC is now a global player, competing with its peers and also having its input in the future low-carbon electricity system. This book challenges the popular interpretation of Chinese government. Piling detail on detail, it provides a comprehensive picture of Chinese political economy that is both new and utterly convincing.

Book Description :

Living sustainably is not just about preserving the wilderness or keeping nature pristine. The transition to a green economy depends on cities. Economic, technological, and cultural forces are moving people out of rural areas and into urban areas. If we are to avert climate catastrophe, we will need our cities to coexist with nature without destroying it. Urbanization holds the key to long-term sustainability, reducing per capita environmental impacts while improving economic prosperity and social inclusion for current and future generations. The Sustainable City provides a broad and engaging overview of the urban systems of the twenty-first century. It approaches urban sustainability from the perspectives of behavioral change, organizational management, and public policy, looking at case studies of existing legislation, programs, and public-private partnerships that strive to align modern urban life and sustainability. The book synthesizes the disparate strands of sustainable city planning in an approachable and applicable guide that highlights how these issues touch our lives on a daily basis, including the transportation we take, the public health systems that protect us, where our energy comes from, and what becomes of our food waste. This second edition of The Sustainable City dives deeper into the financing of sustainable infrastructure and initiatives and puts additional emphasis on the roles that individual citizens and varied stakeholders can play. It also reviews current trends in urban inequality and discusses whether a model of sustainability that embraces a multidimensional approach to development and a multistakeholder approach to decision making can foster social inclusion. It features many more examples and new international case studies spanning the globe.
