Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities
Optimization of energy consumption in future intelligent energy networks (or
Smart Grids) will be based on grid-integrated near-real-time communications
between various grid elements in generation, transmission, distribution and
loads. This paper discusses some of the challenges and opportunities of
communications research in the areas of smart grid and smart metering. In
particular, we focus on some of the key communications challenges for realizing
interoperable and future-proof smart grid/metering networks, smart grid
security and privacy, and how some of the existing networking technologies can
be applied to energy management. Finally, we also discuss the coordinated
standardization efforts in Europe to harmonize communications standards and
protocols.Comment: To be published in IEEE Communications Surveys and Tutorial
Bringing power and progress to Africa in a financially and environmentally sustainable manner
EXECUTIVE SUMMARY:
The future of electricity supply and delivery on the continent of Africa represents one of the thorniest
challenges facing professionals in the global energy, economics, finance, environmental, and
philanthropic communities.
Roughly 600 million people in Africa lack any access to electricity. If this deficiency is not solved,
extreme poverty for many Africans is virtually assured for the foreseeable future, as it is widely
recognized that economic advancement cannot be achieved in the 21st Century without good electricity
supply. Yet, if Africa were to electrify in the same manner pursued in developed economies around the
world during the 20th Century, the planet’s global carbon budget would be vastly exceeded, greatly
exacerbating the worldwide damages from climate change.
Moreover, due to low purchasing power in most African economies and fiscal insolvency of most African
utilities, it is unclear exactly how the necessary infrastructure investments can be deployed to bring
ample quantities of power – especially zero-carbon power – to all Africans, both those who currently are
unconnected to any grid as well as those who are now served by expensive, high-emitting, limited and
unreliable electricity supply.
With the current population of 1.3 billion people expected to double by 2050, the above-noted
challenges associated with the African electricity sector may well get substantially worse than they
already are – unless new approaches to infrastructure planning, development, finance and operation
can be mobilized and propagated across the continent.
This paper presents a summary of the present state and possible futures for the African electricity
sector. A synthesis of an ever-growing body of research on electricity in Africa, this paper aims to
provide the reader a thorough and balanced context as well as general conclusions and
recommendations to better inform and guide decision-making and action. [TRUNCATED]This paper was developed as part of a broader initiative

A means to an industrialisation end? Demand side management in Nigeria
Electricity is essential for economic development and industrialisation processes. Balancing demand and supply is a recurrent problem in the Nigerian electricity market. The aim of this work is to assess the technical and economic potential of Demand Side Management (DSM) in Nigeria given different future levels of industrialisation. The paper places industrialisation at the centrefold of the appraisal of DSM potential in Nigeria. It does so by designing industrialisation scenarios and consequently deriving different DSM penetration levels using a cost-optimisation model. Findings show that under the high industrialisation scenario by the year 2050 DSM could bring about 7 billion USD in cumulative savings thanks to deferred investment in new generation and full deployment of standby assets along with interruptible programmes for larger industrial users. The paper concludes by providing policy recommendations regarding financial mechanisms to increase DSM deployment in Nigeria. The focus on DSM serves to shift the policy debate on electricity in Nigeria from a static state versus market narrative on supply to an engagement with the agency and influence on industrial end-users
Green revolution 2.0: a sustainable energy path
This repository item contains a single issue of Sustainable Development Insights, a series of short policy essays that began publishing in 2008 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future. The series seeks to promote a broad interdisciplinary dialogue on how to accelerate sustainable development at all levels.The Green Revolution in agriculture greatly increased crop yields and averted mass starvation, but it also turned small farms into factory farms that concentrated production in a few locations and reduced the diversity of crops. In this paper, Professor Nalin Kulatilaka, Co-Director of BU’s Clean Energy & Environmental Sustainability Initiative, calls for a Green Energy Revolution that decentralizes energy supplies through a smart electricity network. He argues that such a revolution could provide for a diversity of energy sources located closer to users, which in turn could shift consumption patterns, reduce losses and decrease overall energy demand. He concludes that shifting to such a system “will adopt clean energy technologies while fostering new businesses, creating new jobs and ultimately empowering society to reach new heights in energy conservation and sustainability“
An examination of the feasibility of producing green hydrogen from curtailed, onshore wind power using a North Wales case study
Onshore wind power is considered one of the most important future energy sources, but its intermittent and variable nature present a number of challenges to increasing the supply and penetration of wind energy in our energy systems, including the loss of renewable energy through curtailment. Hydrogen, which has for many years been considered an interesting option is now seriously considered as a possible solution to some of these challenges presented by renewable energy intermittency, variability as well as the decarbonisation challenge of other sectors. Use of hydrogen in this way has recently seen a convergence of political and industry support. This study will aim to examine the feasibility of producing hydrogen from curtailed onshore wind energy using a wind farm in North Wales as a case study. The research begins with a literature review and an analysis of the technical, economic, and environmental feasibility of hydrogen production from onshore wind before presenting an original economic model, offering results on the specific economic feasibility of producing hydrogen from the curtailed generation of a wind farm in North Wales. The results suggest that supplying hydrogen into the transport sector is the most economically feasible solution. The results also consider the economic feasibility of wholesale and gas grid supply. The results are analysed within the geographical context of the case study site and the opportunities for supply and demand of hydrogen which currently exist or planned future development. This research provides in depth analysis and tools to enable better understanding the relationship between onshore wind and hydrogen production in Wales, UK
