Introduction

Introduction and Overview

The policy challenges associated with global warming, the prospect of increasingly expensive fossil fuels, and the recent re-emergence of serious concerns about the safety of nuclear power after the Fukushima accident in Japan are encouraging many western and Asian economies to develop smart grids (SGs) as a component of their energy policy portfolios. This introductory chapter first discusses the evolving definitions of SGs, and the five major applications of these technologies. We will then provide an energy sector outlook, highlighting the major energy developments in the near future that may affect SG deployment.  We will conclude with an overview of the objectives and structure of the book.

A Holistic View on Developing Smart Grids for a Low-Carbon Future

This chapter provides a holistic overview of the development of smart grids as an essential element for a low-carbon future. It examines how four key aspects, namely technology, economics, regulation/policy, and social acceptance, are complementary and therefore need to be considered concurrently for the deployment of smart grids. This chapter emphasizes that there is no one-size-fit-all solution, and the choice of solutions differs across countries and localities. A good understanding of local features such as historical, cultural, resources, market, and regulatory factors that coexist with strong and consistent commitment, careful road mapping, learning through trials as well as supporting innovation and research are required for the effective transition toward different smart grid systems in a low-carbon world.

Status and Prospects of European Renewable-Based Energy Systems Facilitated by Smart Grid Technologies

Renewable energy plays an important role in the future energy framework of the European Union. The European Union will reach a 20 % share of renewable energy in total energy consumption and increase energy efficiency by 20 % by 2020. Smart grids will be the backbone for facilitating the integration of renewable energy resources into future energy systems. The plans and status of renewable energy resources development and energy policy in Europe are introduced in this chapter. The development of smart grid technologies for facilitating the renewable-based energy systems in the European Union is also discussed. The role of Denmark, one of the leading countries for developing smart grid technologies and using renewable energy resources, has been emphasized in this chapter.

Arcturus: An International Repository of Evidence on Dynamic Pricing

This chapter introduces Arcturus, an international database of dynamic pricing and time-of-use pricing studies. It contains the demand response impacts of 163 pricing treatments that were offered on an experimental or full-scale basis in 34 projects in seven countries located in four continents. The treatments included various types of dynamic pricing rates and simple time-of-use rates, some of which were offered with enabling technologies such as smart thermostats. The demand response impacts of these treatments vary widely, from 0 % to more than 50 %, and this discrepancy has led some observers to conclude that we still do not know whether customers respond to dynamic pricing. We find that much of the discrepancy in the results goes away when demand response is expressed as a function of the peak-to-off-peak price ratio. We then observe that customers respond to rising prices by lowering their peak demand in a fairly consistent fashion across the studies. The response curve is nonlinear and is shaped in the form of an arc: as the price incentive to reduce peak use is raised, customers respond by lowering peak use, but at a decreasing rate. We also find that the use of enabling technologies boosts the amount of demand response. Overall, we find a significant amount of consistency in the experimental results, especially when the results are disaggregated into two categories of rates: time-of-use rates and dynamic pricing rates. This consistency evokes the consistency that was found in earlier analysis of time-of-use pricing studies that was carried out by EPRI in the early 1980s. Our analysis supports the case for the rollout of dynamic pricing wherever advanced metering infrastructure is in place.

Microgrids and Distributed Energy Future

Microgrid appears with the development of distributed generations (DGs) and distributed renewable energy resources. It is usually located in low voltage networks and connected to the power grid through switches. In remote or isolated areas, microgrid is an alternative way of power supply instead of installing expensive long-distance transmission lines. A microgrid combines DGs, loads, distributed energy storages, and cogenerations to form a mini power system. The system could be operated as grid-connected mode or islanded mode. The autonomous operation is one of the features of microgrid. Distributed renewable energy resources and small-scale clean energy generating units are the major generation resources in microgrids. The development of microgrids and distributed clean energy generations will be one of the solutions to carbon emissions and global warming. Microgrid is a transition step from conventional power systems to smart grid. The demand management and generation control in a microgrid could significantly improve energy efficiency and system operation. In this chapter, the concept and development of microgrid are introduced. The challenges and operation issues are discussed for microgrids. In the end, the operating microgrids all over the world are introduced.

Communication and Network Security Requirements for Smart Grid

To relieve the problems of climate change due to global warming, increased renewable energy generation based on wind and solar has been advocated in the power grid. Due to the intermittent nature of such generation, and the requirement of real-time power balance between generation and consumption, increased renewable energy generation may cause instability in the power grid. The smart grid is an attempt to deploy information and communication technologies (ICT) on the power grid to solve the instability problem due to renewable energy sources. The smart grid also enables customer participation in such applications as differential pricing and demand response and promises improved grid operating efficiencies, self-healing capabilities, and resiliencies against cyber attacks. In this chapter, we discuss the communication and network security requirements for smart grid.

Smart Grids: The Regulatory Challenges

Smart grids present major potential benefits in terms of economic, environmental, and social considerations. The deployment of smart grids however requires not only technological advancement but also the ability to overcome many regulatory barriers. This chapter brings regulator perspectives—an area that is under-explored—into the field of smart grid studies. We examine why regulators should be concerned about smart grid developments, the nature of the regulatory challenges they may face, and what they can do to address these challenges. We have two major findings. Firstly, we demonstrate that smart grids present new challenges to regulators. Regulators are faced with three major challenges: utility disincentives, pricing inefficiencies, and cybersecurity and privacy. Market liberalisation, decoupling, dynamic pricing, and protocols and standards on cybersecurity are the major mechanisms that regulators can deploy to address these issues. Secondly, our international case studies of countries and cities provide an overview of a variety of actual regulatory initiatives in place. This overview shows how economies have pioneered a variety of regulatory approaches that tend to be more participatory to better respond to the more dynamic stakeholder landscape that is emerging.

i-Energy: Smart Demand-Side Energy Management

Much of the discussion concerning smart grids focuses on the potential benefits of technological advances to power suppliers. However, there are many possible advantages that may benefit consumers as electricity grids exploit more of the opportunities provided by the cyber network society and emerge as a form of supporting social infrastructure. A critical element in the development of advanced consumer-friendly grids is the notion of an integrated system for energy management from the consumer’s viewpoint. Here, we present such a concept—i-Energy—for smart demand-side energy management. The concept embodies four main elements: Smart Tap Network, Energy on Demand Protocol, Power Flow Coloring, and Smart Community. The key features of each are explained, and the characteristics and effectiveness of the required supporting technologies as demonstrated by ongoing research are presented. The importance of bringing together key stakeholders to achieve effective collaboration to implement the i-Energy concept is also emphasized.

Switching Perspectives: Creating New Business Models for a Changing World of Energy

Traditional electric utility business models are becoming rapidly outdated. Policy changes, new energy technologies and more demanding consumers are driving the need to move away from purely operation-oriented approaches to more consumer-driven models. With these new business imperatives and a resulting need to focus on industry-level business model innovation, we explore how new models could evolve, and their benefits to consumers, utilities and other stakeholders. We also discuss the challenges ahead and the capabilities required for realizing this transformation.

Smart Transmission Grids Vision for Europe: Towards a Realistic Research Agenda

Smart grids have attracted significant attention lately, and one can even speak of hype. However, much of the attention is paid to the distribution side and consumer interaction. Nevertheless, also at the transmission-level important improvements can be achieved through farsighted and careful intelligent grid design and implementation. This chapter describes and proposes a realistic research agenda in which smart transmission grid (STG) research may operate, with focus on operational planning and operations of the pan-European electricity grid. Firstly, a research outlook seen from current European policy is laid out to redefine the most consequential research directions liked to the needs of transmission systems from real time up to planning. Secondly, operations (real time to hours) of the transmission system are discussed, and monitoring and control technologies that can be achieved through the application of synchronized phasor measurement technology are highlighted as a means toward a STG. Next, challenges related to planning (hours to years) are discussed keeping in mind the need of flexibility, coordination, and new methods for assessing system security. Going beyond the purely academic point of view, this chapter specifically aims to bring a realistic approach toward research for electric power transmission to be able to transform into a STG.

Towards Sustainable Energy Systems Through Deploying Smart Grids: The Japanese Case

The deployment of smart grids has a major role to play in Japan’s aspiration to achieve sustainable energy systems. A smart grid in Japan is designed to have an intelligent monitoring system, which not only keeps track of all the energy coming in from diverse sources but also can detect where energy is needed through a two-way communication system that collects data about how and when consumers use power. This chapter examines the vision, concepts, and elements of Japan’s smart grid development. Smart grids are a part of the Japanese government’s ‘go green’ effort to bring Japan to a leadership position in environmental and energy sustainability. This analysis provides an overview of Japan’s major initiatives in deploying smart grids, including smart communities, large-scale smart grid pilot projects in four major cities, as well as overseas collaboration. Major smart grid awareness promotion bodies in Japan are discussed along with their important initiatives for influencing and shaping policy, architecture, standards, and traditional utility operations. Implementing a smart grid will not happen quickly because when Japan does adopt one, it will continue to undergo transformation and be updated to support new technologies and functionality.

Governing the Transition of Socio-technical Systems: A Case Study of the Development of Smart Grids in Korea

This chapter examines the motivations, processes, and outcomes of the development of smart grids in South Korea through the perspectives of governance and innovation systems. Drawing on desktop research and semi-structured interviews, this chapter has two major findings. First, the development of smart grids in Korea has been shaped by various factors including macroeconomic policy, the role of the government, and experimentation. The complex interactions between these factors at the landscape, regime, and niche levels have impacted on the development of smart grids. Second, while Korea’s government-led approach has its strengths in driving change, it has also exposed weaknesses in the country’s ability to mobilise the private sector and consumer participation. Major obstacles including partial electricity market reform and public distrust exist. A systemic perspective is needed for policy in order to accommodate the changes required for smart grid development. Regulatory reforms, particularly price-setting mechanisms, and consumer engagement are priority areas for policy change.

Developing Super Smart Grids in China: Perspective of Socio-technical Systems Transition

This chapter adopts the framework of socio-technical systems transition to discuss the development of smart grid (SG) in China. Multi-level perspective (MLP) analysis, namely landscape, regime, and niches, is presented to set the institutional background of China’s power sector. Then, a scenario of power supply and demand is compiled, and its main features are elaborated to justify the necessity of developing SGs. The overall transition pathways of China’s power sector are drafted, and then, the road map for developing SGs in China is proposed. Key policy implications are as follows: first, working out clear national strategy and road map for SG development and carrying out integrated translation research and strong front-end support; second, restructuring power sector in parallel with SG development; and third, reforming pricing mechanism and empowering the customers with rights to choose service/enter power market.

Systemische Notwendigkeit zur Weiterentwicklung von Hybridnetzen

Die Entwicklung des mitteleuropäischen Energiesystems und insbesondere die Weiterentwicklung der Energieinfrastruktur sind konfrontiert mit einer stetig steigenden Diversität an Herausforderungen, aber auch mit einer zunehmenden Komplexität in den Lösungsoptionen. Vor diesem Hintergrund steht die Weiterentwicklung von Hybridnetzen symbolisch für das ganze sich in einer Umbruchsphase befindliche Energiesystem: denn der Notwendigkeit einer Schaffung und Bildung der Hybridnetze aus systemischer und volkswirtschaftlicher Perspektive steht sozusagen eine Komplexitätsfalle gegenüber, mit der die Branche in der Vergangenheit in dieser Intensität nicht konfrontiert war. Jetzt gratis downloaden!
