The smart grid is a hot topic at utility executive meetings and broader transmission and distribution (T&D) utility forums across the country. The concept still elicits mixed reaction, but there is increasing agreement on a common defi nition of "smart grid," as well as an emerging confi dence that the smart grid embodies a set of technology investments that can transform the way service is delivered to customers. In addition to cost and service quality improvements, the smart grid is increasingly being linked to environmental goals, including attaining renewable-energy targets and reducing carbon emissions. A wide variety of players--venture capital companies, software and application providers, niche engineering firms--have entered the smart-grid value chain with material investments. Utilities are getting bolder in their program designs and in integrating smart-grid investments with their aspirations for energy effi ciency and renewables. State regulators have been approving pilot programs and building precedents with favorable investment decisions. With the development taking real shape, there are still areas to be cautious about, however. Systematic, wide-scale deployment of demand response has yet to be demonstrated. Systems integration is a considerable challenge. Worries regarding technology obsolescence continue, with new twists as new communications capabilities emerge.  相似文献

The huge energy demand coming from the increasing diffusion of plug-in electric vehicles (PEVs) poses a significant challenge to electricity utilities and vehicle manufacturers in developing smart charging systems interacting in real time with distribution grids.These systems will have to implement smart charging strategies for PEV batteries on the basis of negotiation phases between the user and the electric utility regarding information about battery chemistries, tariffs, required energy and time available for completing the charging. Strategies which adapt the charging current to grid load conditions are very attractive. Indeed, they allow full exploitation of the grid capacity, with a consequent greater final state of charge and higher utility financial profits with respect to approaches based on a fixed charging rate.The paper demonstrates that the charging current should be chosen also taking into account the effect that different charging rates may have on the charging efficiency. To this aim, the performances of two smart variable-rate-based charging strategies, taken as examples, are compared by considering possible realistic relationships between the charging efficiency and the charging rate. The analysis gives useful guidelines for the development of smart charging strategies for PEVs as well as for next-generation battery charging and smart grid management systems.  相似文献

Electric utilities and regulators face difficult challenges evaluating new energy efficiency and smart grid programs prompted, in large part, by recent state and federal mandates and financial incentives. It is increasingly difficult to separate electricity use impacts of individual utility programs from the impacts of increasingly stringent appliance and building efficiency standards, increasing electricity prices, appliance manufacturer efficiency improvements, energy program interactions and other factors. This study reviews traditional approaches used to evaluate electric utility energy efficiency and smart-grid programs and presents an agent-based end-use modeling approach that resolves many of the shortcomings of traditional approaches. Data for a representative sample of utility customers in a Midwestern US utility are used to evaluate energy efficiency and smart grid program targets over a fifteen-year horizon. Model analysis indicates that a combination of the two least stringent efficiency and smart grid program scenarios provides peak hour reductions one-third greater than the most stringent smart grid program suggesting that reductions in peak demand requirements are more feasible when both efficiency and smart grid programs are considered together. Suggestions on transitioning from traditional end-use models to agent-based end-use models are provided.  相似文献

The “smart grid” represents one of the greatest potential advances in electricity delivery infrastructure in the past century. While the technologies that collectively comprise the smart grid have existed for decades, the potential for changing the way that electricity is generated, delivered, utilized and priced is revolutionary. Not surprisingly, many countries have undertaken initiatives to rollout smart grid infrastructure at an aggressive pace. Understanding the fundamental changes that the smart grid is likely to introduce is important for the development of future energy scenarios and the environmental, social and economic implications of these scenarios. Here we present an overview of the emerging smart grid and outline a few implications for the energy modeling community. Specifically, we discuss the potential for the smart grid to act as an enabling technology for renewable energy integration, price-responsive electricity demand, electrified transportation and distributed energy production as examples of how the smart grid may fundamentally change future energy system scenario development. The smart grid is being deployed and implemented much faster than we are able to fully consider its implications, and in some cases public policy has a long way to go before it catches up with the pace of smart grid technology deployment.  相似文献

Grid operators increasingly have to collaborate with other actors in order to realize smart grid innovations. For routine maintenance, grid operators typically acquire technologies in one-off transactions, but the innovative nature of smart grid projects may require more collaborate relationships. This paper studies how a transactional versus relational approach to governing smart grid innovation projects affects incentives for other actors to collaborate. We analyse 34 cases of smart grid innovation projects based on extensive archival data as well as interviews. We find that projects relying on relational governance are more likely to provide incentives for collaboration. Especially non-financial incentives such as reputational benefits and shared intellectual property rights are more likely to be found in projects relying on relational governance. Policy makers that wish to stimulate smart grid innovation projects should consider stimulating long-term relationships between grid operators and third parties, because such relationships are more likely to produce incentives for collaboration.  相似文献

In today's world striving for efficiency in every sector, especially power generation and distribution, smart grids emerge as the solution for efficiently meeting the increasing demand. They adjust themselves to optimally deliver energy at the lowest cost and highest quality possible. The grid successfully makes use of renewable energy resources, electric vehicles, and smart pricing techniques in its attempt to achieve energy efficiency. It also promotes a greener environment by striving to reduce greenhouse gas emissions. Information communication technology (ICT) helps the grid in collecting consumption data from the consumers and in sharing tariff information. ICT also helps to gather information about the status of the grid with regard to aspects like power quality, faults etc. The purpose of this paper is to review recent literature with a view to comprehensively present the technologies employed in the smart grid for achieving energy efficiency and the challenges involved therein.  相似文献

The smart grid is an important but ambiguous element in the future transition of the European energy system. The current paper unpacks one influential national vision of the smart grid to identify what kinds of expectations guide the work of smart grid innovators and how the boundaries of the smart grid are defined. Building on data from a scenario exercise within a large Danish smart grid project, we examine how the smart grid and the conditions for its realization are defined and delimited. Our findings show that the smart grid hype embodies several implicit expectations that serve to guide research and investment and to attract new players into the field. A scenario process such as that demonstrated in this article can serve to articulate some of these implicit assumptions and help actors to navigate the ongoing transition. On the basis of our analysis, European policymakers might consider how their (intentional or unintentional) choices serve to create or maintain certain boundaries in smart grid development: for example, an exclusive focus on electricity within the broader context of a sustainable energy system. As serious investment starts being made in the smart grid, concepts like the supergrid, flexible demand and a broader smart energy system will start competing with each other.  相似文献

Utilities are increasing their investment in smart grid technologies because of the rising demand for electricity, the aging transmission and distribution infrastructure in developed countries and the need for real-time visibility of energy supply and demand to optimize service reliability and cost. Government policies are contributing to this rising investment in the smart grid in many countries around the globe. Using Rothwell and Zegveld's innovation policy framework as a starting point, this paper compares innovation policy in smart grids across the Pacific; specifically, China and the USA. This research describes the policy tools used by both countries and presents results that indicate national preferences for innovation policy that differ in the ways in which they are linked with the state of the power system. China has preferred to use “supply-side policy,” which focuses on “public enterprise, scientific and technical development and legal regulation.” The USA has preferred to use “environmental-side policy,” which focuses on “scientific and technical development, financial, political and public enterprise.” This paper also describes in detail a number of innovation policies being pursued in the smart grid industry in both China and the USA.  相似文献
