Scenarios for the development of smart grids in the UK: literature review
Smart grids are expected to play a central role in any transition to a low-carbon energy future, and much research is currently underway on practically every area of smart grids. However, it is evident that even basic aspects such as theoretical and operational definitions, are yet to be agreed upon and be clearly defined. Some aspects (efficient management of supply, including intermittent supply, two-way communication between the producer and user of electricity, use of IT technology to respond to and manage demand, and ensuring safe and secure electricity distribution) are more commonly accepted than others (such as smart meters) in defining what comprises a smart grid.
It is clear that smart grid developments enjoy political and financial support both at UK and EU levels, and from the majority of related industries. The reasons for this vary and include the hope that smart grids will facilitate the achievement of carbon reduction targets, create new employment opportunities, and reduce costs relevant to energy generation (fewer power stations) and distribution (fewer losses and better stability). However, smart grid development depends on additional factors, beyond the energy industry. These relate to issues of public acceptability of relevant technologies and associated risks (e.g. data safety, privacy, cyber security), pricing, competition, and regulation; implying the involvement of a wide range of players such as the industry, regulators and consumers.
The above constitute a complex set of variables and actors, and interactions between them. In order to best explore ways of possible deployment of smart grids, the use of scenarios is most adequate, as they can incorporate several parameters and variables into a coherent storyline. Scenarios have been previously used in the context of smart grids, but have traditionally focused on factors such as economic growth or policy evolution. Important additional socio-technical aspects of smart grids emerge from the literature review in this report and therefore need to be incorporated in our scenarios. These can be grouped into four (interlinked) main categories: supply side aspects, demand side aspects, policy and regulation, and technical aspects.

Transportation connects Boston’s workers, residents and tourists to their livelihoods, health care, education,
recreation, culture, and other aspects of life quality. In cities, transit access is a critical factor determining
upward mobility. Yet many urban transportation systems, including Boston’s, underserve some populations
along one or more of those dimensions. Boston has the opportunity and means to expand mobility access to
all residents, and at the same time reduce GHG emissions from transportation. This requires the
transformation of the automobile-centric system that is fueled predominantly by gasoline and diesel fuel.
The near elimination of fossil fuels—combined with more transit, walking, and biking—will curtail air
pollution and crashes, and dramatically reduce the public health impact of transportation. The City embarks
on this transition from a position of strength. Boston is consistently ranked as one of the most walkable and
bikeable cities in the nation, and one in three commuters already take public transportation.
There are three general strategies to reaching a carbon-neutral transportation system:
• Shift trips out of automobiles to transit, biking, and walking;1
• Reduce automobile trips via land use planning that encourages denser development and affordable
housing in transit-rich neighborhoods;
• Shift most automobiles, trucks, buses, and trains to zero-GHG electricity.
Even with Boston’s strong transit foundation, a carbon-neutral transportation system requires a wholesale
change in Boston’s transportation culture. Success depends on the intelligent adoption of new technologies,
influencing behavior with strong, equitable, and clearly articulated planning and investment, and effective
collaboration with state and regional partners.Published versio

A roadmap for China to peak carbon dioxide emissions and achieve a 20% share of non-fossil fuels in primary energy by 2030
As part of its Paris Agreement commitment, China pledged to peak carbon dioxide (CO2) emissions around 2030, striving to peak earlier, and to increase the non-fossil share of primary energy to 20% by 2030. Yet by the end of 2017, China emitted 28% of the world's energy-related CO2 emissions, 76% of which were from coal use. How China can reinvent its energy economy cost-effectively while still achieving its commitments was the focus of a three-year joint research project completed in September 2016. Overall, this analysis found that if China follows a pathway in which it aggressively adopts all cost-effective energy efficiency and CO2 emission reduction technologies while also aggressively moving away from fossil fuels to renewable and other non-fossil resources, it is possible to not only meet its Paris Agreement Nationally Determined Contribution (NDC) commitments, but also to reduce its 2050 CO2 emissions to a level that is 42% below the country's 2010 CO2 emissions. While numerous barriers exist that will need to be addressed through effective policies and programs in order to realize these potential energy use and emissions reductions, there are also significant local environmental (e.g., air quality), national and global environmental (e.g., mitigation of climate change), human health, and other unquantified benefits that will be realized if this pathway is pursued in China

The adoption of clean energy in Boston’s buildings and transportation systems will produce sweeping
changes in the quantity and composition of the city’s demand for fuel and electricity. The demand for
electricity is expected to increase by 2050, while the demand for petroleum-based liquid fuels and
natural gas within the city is projected to decline significantly. The city must meet future energy demand
with clean energy sources in order to meet its carbon mitigation targets. That clean energy must be
procured in a way that supports the City’s goals for economic development, social equity, environmental
sustainability, and overall quality of life. This chapter examines the strategies to accomplish these goals.
Improved energy efficiency, district energy, and in-boundary generation of clean energy (rooftop PV)
will reduce net electric power and natural gas demand substantially, but these measures will not
eliminate the need for electricity and gas (or its replacement fuel) delivered into Boston. Broadly
speaking, to achieve carbon neutrality by 2050, the city must therefore (1) reduce its use of fossil fuels
to heat and cool buildings through cost-effective energy efficiency measures and electrification of
building thermal services where feasible; and (2) over time, increase the amount of carbon-free
electricity delivered to the city. Reducing energy demand though cost effective energy conservation
measures will be necessary to reduce the challenges associated with expanding the electricity delivery
system and sustainably sourcing renewable fuels.Published versio
Review of UK microgeneration. Part 1 : policy and behavioural aspects
A critical review of the literature relating to government policy and behavioural aspects relevant to the uptake and application of microgeneration in the UK is presented. Given the current policy context aspiring to zero-carbon new homes by 2016 and a variety of minimum standards and financial policy instruments supporting microgeneration in existing dwellings, it appears that this class of technologies could make a significant contribution to UK energy supply and low-carbon buildings in the future. Indeed, achievement of a reduction in greenhouse gas emissions by 80% (the UK government's 2050 target) for the residential sector may entail substantial deployment of microgeneration. Realisation of the large potential market for microgeneration relies on a variety of inter-related factors such as microeconomics, behavioural aspects, the structure of supporting policy instruments and well-informed technology development. This article explores these issues in terms of current and proposed policy instruments in the UK. Behavioural aspects associated with both initial uptake of the technology and after purchase are also considered

A Modelling Tool for Distribution Networks to Demonstrate Smart Grid Solutions
The increased deployment of low carbon technologies in power distribution networks, particularly at the distribution level, is expected to cause significant problems to network operation unless existing networks are appropriately adapted and actively controlled as part of a smart grid. This paper describes the development of a modelling tool to examine Smart Grid solutions to a number of issues affecting low voltage power distribution networks. Use of the tool in the context of transformer overload, line overvoltage, active load control, Grid storage and Black Start analysis is examined
