Introduction
Worldwide interest in reducing the emission of greenhouse gases associated with the production of electrical
energy has promoted a growth in distributed energy resources and renewable generation. A significant
proportion of the electrical distribution infrastructure in Europe is reaching an age where it warrants major
replacement or refurbishment. In considering such a major programme for asset replacement, it would seem
sensible to look at the design and operation of the distribution infrastructure to make sure that the new
networks make best use of available technology to address environmental concerns, for example minimising
network losses and encouraging the connection of distributed generation. These considerations have given
rise to the term ‘Smart Grids’. There are now a number of trial projects being conducted across Europe, and
other parts of the developed world, to investigate the potential benefits of Smart Grids. To support the
development of Smart Grids it would be advantageous if there were a suite of technical standards that
described the various components that make up the Smart Grid and how these components operate in
concert to deliver the benefits of improved network operations and reduced environmental emissions.
This Technical Report is based on the descriptions of 32 Smart Grid projects in seven countries. By collating
the experiences of these early Smart Grid projects, it is intended that Cenelec will be able to identify those
areas that would benefit from standardization.
1 Scope
This Technical Report provides an overview of the technical contents and regulatory arrangements of some
1)
32 of the many Smart Grid projects that are currently in operation, or under construction, within Europe .
This Technical Report is intended to provide useful information to those organisations and individuals that are
currently engaged or about to become engaged in developing Smart Grids. It is also intended that this
Technical Report will be used to support the development of relevant standards by presenting the key learning
points from early Smart Grid projects – it is widely accepted that the publication of relevant standards will
accelerate the development of Smart Grids. It is recognised that this Technical Report only covers a sample of
the Smart Grid projects within Europe; it would be impractical to attempt to include every project. It is
assessed that the 32 projects shown in this Technical Report are sufficiently representative to provide
information and draw early conclusions. Clause 2 of this Technical Report provides a brief overview of all
32 projects, Annex A contains details of the 32 projects as supplied by the countries that participated in the
drafting of this Technical Report.
NOTE 1 In order to avoid losing potentially useful information, the details presented in Annex A are very close to the
raw data provided by the different countries, with only minor editorial amendments made in the drafting of this Technical
Report.
One of the key objectives of this Technical Report is to identify the learning objectives for each of the Smart
Grid projects, i.e. why is the project is being carried out and how the success of the project in meeting these
objectives will be determined.
NOTE 2 It is intended that the learning contained in this Technical Report, in particular the learning around what type of
standards are required to support the development of Smart Grids, will provide useful input to the joint CEN/Cenelec/ETSI
Smart Grid Co-ordination Group (SGCG). The SGCG has been established to support the requirements set out in the
European Commission Smart Grid Mandate M/490, March 2011.
NOTE 3 In drafting this Technical Report the working group were made aware of a report with a similar scope to this
2)
Technical Report that was being produced by the European Commission’s Joint Research Centre (JRC) . The JRC
report is now published and publically available. It is assessed that this Technical Report and the JRC report are
complementary documents; the JRC report provides a high-level view on 220 projects that are being conducted across
Europe whereas this Technical Report provides more detailed information on 32 projects.
This Technical Report presents the situation for the 32 projects as they are at the time of writing; as time
moves on, it might be necessary to update this Technical Report or to produce a second edition containing
information on more recent projects and learning from existing projects, such as those documented in this
Technical Report.
2 Project overview
2.1 Rationale for developing the Smart Grid
All of the projects described in this Technical Report are taking place on electricity distribution networks; these
networks are owned and operated by distribution system operators (DSO’s), sometimes referred to as
distribution network operators (DNO’s).
———————
1) All Cenelec member countries were invited to submit example projects for inclusion in this Technical Report, the
32 projects presented in this Technical Report represent the sum total of all projects that were submitted for
consideration.
2) JRC Report, June 2011: A view on Smart Grid projects in Europe: lessons learned and current developments.
From the 32 Smart Grid projects described in this Technical Report, it is possible to determine a number of
areas of common interest; however, there are also some significant differences. One common theme behind
all projects is the need to try new technology in order to evaluate the potential benefits. Most of the projects
are focussed on solving potential network problems rather than solving actual problems that exist on these
networks now. The capacity of the low-voltage network to accommodate increasing levels of micro-generation,
electric vehicles, heat pumps and other technologies is one of the most common potential problems that the
Smart Grid trial is looking to address. A significant number of the trials are looking at the potential for networks
operators to utilise controllable demand and network monitoring in order to accommodate more renewable
generation connected to the MV network, this inevitably means a major requirement for customer interaction.
2.2 Costs and funding
The total cost of the 32 projects is approximately 516 M€ with a range from under 1 M€ to just over 60 M€,
most projects sit in the range 2 M€ to 20 M€.
Only five of the 32 Smart Grid projects are funded entirely by the network operator i.e. there is no regulatory
allowance for this expenditure, although some have received a contribution from other businesses with an
interest in developing a Smart Grid. The remaining 27 projects receive a contribution to the overall project
funding that comes from either central government or from regulated income, which comes from the electricity
customers. The use of external funding is seen as incentivising network operators to conduct trials of new
technology that might not be the most cost effective solution to a network constraint.
2.3 Duration
The typical duration of the Smart Grid projects described in this Technical Report is 3 years to 4 years. There
is one project, NO-2 (see Table A.10), that has a duration of ten years, the reason for this is that Norway
3)
intend to use this project as a “national laboratory” to trial different use cases over the ten-year period.
It is assessed that year one of the Smart Grid trial will be associated with planning, constructing and
commissioning. Customer engagement will take place throughout the project, most significantly at the
planning stage where customer support is essential. Once the Smart Grid is operational, performance will be
monitored and trial objectives evaluated. It is assessed that the minimum monitoring period to give robust
results is one year; a monitoring period of two years would increase the confidence in the results. Therefore, a
trial period of 3 years to 4 years would appear to be the optimum time over which to implement and robustly
evaluate a Smart Grid trial.
The majority of the projects described in this Technical Report, 27 out of 32, are designed to be permanent
installations, with the intention of taking the Smart Grid from the status of proto-type to business as usual. Of
the five non-permanent installations, for all but one it is intended to leave some of the Smart Grid
infrastructure in-situ permanently. The clear intention is for the Smart Grid trials to set the design
specifications for future networks.
Info will come out during the course of the project that can be fed into other projects and/or fed back into the
project where the learning was developed, all aimed at improving the benefits that can be derived from the
Smart Grid.
———————
3) The term “Use Case” refers to the use of a particular type of technology or system within a smart grid. The term "Use
Case" has arisen during period when this Technical Report was being drafted. There is work going on within Cenelec
and IEC to collect and catalogue generic Use Cases.
2.4 Project status
Nine of the projects described in this Technical Report have progressed to the development stage; 22 projects
are still at the planning stage and one project is un-defined. The design and operation of electricity distribution
networks has remained largely unchanged for decades and the vision of a Smart Grid requires significant
investment in equipment and skills to make it a reality. Therefore, it should come as no surprise that it has
proved a slow process to move from planning to development.
2.5 Stakeholders
4)
In addition to the DNO’s / DSO’s who own and operate the distribution networks there are a host of other
parties (stakeholders) who have an interest in Smart Grids, including Regulators, Customers, Government
bodies, Academia, Equipment suppliers and Consultants; all parties are having to adapt to a changing
approach to designing and operating electricity networks. A common theme from all of the projects described
in this Technical Report is the pivotal role that customers will need to play if the Smart Grid trial is to become a
success. A number of the projects are investigating the potential to influence and/or rely on customer
behaviour in order to optimise network capacity in terms of the ability to accommodate new generation and/or
demand.
2.6 Networks and components
The questionnaire sought to gain information on the types of networks that have been chosen for the Smart
Grid trials and information on the type of new technologies that are being trialled. The intention of the
questionnaire was to gain an understanding of the rationale behind the selection of a particular network and
the particular suite of Smart Grid components; and to identify if there are common areas that would benefit
from a standardized approach to design / connection / operation.
The majority of the projects described in this Technical Report are focussed on the low voltage network, with a
heavy emphasis on customer engagement via the use of smart meters. There is a mixture of area types from
urban all underground cable networks to mixed overhead line and underground cable networks in suburban
and rural areas. Network operators appear to be keen to investigate the potential viability of Smart Grids
across the full range of area and network types, although the majority of the projects are based in urban and
suburban areas in order to take advantage of the higher customer population and therefore the greater
learning opportunity for the projects.
A common theme across all projects is the desire to identify how much extra capacity can be extracted from
the existing networks by optimising the use of demand and generation. To achieve this optimisation a number
of the projects plan to employ smart meters with the associated communication infrastructure. In addition,
some projects are trialling the use of generation to support network voltage control by control the power and
reactive power of the generation.
A large number of the projects include the provision of supplies to electric vehicle (EV) charging points; at
least two of the projects are associated with major EV initiatives. Network operators are keen to understand
the impact that EV charging will have on the distribution network, what will be the daily, weekly, annual
charging regimes and what will be the diversity between users. Some projects are investigating the potential
for intelligent charging, where the charging of EV’s is aligned with the output from wind turbines connected at
HV or above.
Heat Pumps (HP’s) feature in some projects. As with EV’s the network operators are keen to understand the
impact that HP’s might have on the low voltage network, in particular the operating cycles and how customer
usage might be influenced by providing the customer with information via smart meters and the by the use of
innovative tariffs.
———————
4) There are cases where DNOs/DSOs are operators but not owners of a distribution network.
Battery energy storage features in ten of the projects. Some projects are planning to install standalone battery
storage units, ranging in size from kW to 2,5 MW. In all cases it appears that the intention of including storage
in the trial is to investigate the potential for batteries and other storage media (hot water heating in one project
and cold stores another project) to support network optimisation by absorbing surplus generation and/or to
reduce peaks in demand. Although some of the responses have made reference to electric vehicle (EV)
batteries in response to the question on storage, it has been confirmed that there is currently no intention for
these projects to investigate the potential for the batteries in EVs to act as an energy storage component that
can be called upon to support the network.
2.7 Generation
The questionnaire asked for information on the number, size and type of any generation installed within the
Smart Grid trial:
It has been reported that all projects include generation connected to the distributed network (distributed
generation). There is a range of generation types and sizes ranging from kW photovoltaic generation
connected at LV through to 10’s MW Wind, Hydro, Biogas, CHP connected at MV / HV. In most countries,
there are financial incentives that encourage the connection of renewable generation. These incentives have
accelerated the growth of distributed generators seeking connection. The Smart Grid trials are investigating
the opportunities for connecting more generation to existing networks by optimising the use of both demand
and generation, which is reliant upon information and communications in order to dynamically permit or
constrain operation of the demand and/or generation. Some projects are investigating the use of dynamic
thermal ratings of overhead lines in order to determine the dynamic capacity of the line, which in turn will
permit / constrain the generation connected to the network.
2.8 Customers
A major requirement for the Smart Grid is customer engagement: if customers cannot be influenced to modify
their demand, either actively or passively, it will limit the opportunities for network optimisation.
The projects described in this Technical Report are mainly concerned with customers connected at LV,
typically residential (domestic) customers. Two projects are looking at the role that can be played by larger
customers in managing their demand in response to signals from the network operator, again these projects
are aimed at optimising the operation of the network, in these cases it will be the HV and EHV networks.
2.9 Standards
As described in the Scope, it is intended that the learning contained in this Technical Report, in particular the
learning around what type of standards are required to support the development of Smart Grids, will provide
useful input to the joint CEN/Cenelec/ETSI Smart Grid Co-ordination Group (SGCG). The SGCG has a sub-
group that is tasked with identifying a “first set of standards” for Smart Grids.
A small number of project descriptions have suggested that there is a need for standards in the areas of
Interconnection, Interoperability (between smart appliances and smart network components) and the
connection of electric vehicles. Other projects have suggested that no new standards are required for the
Smart Grid trials to take place; and some project descriptions have suggested that it is too early to decide
which areas require new standards.
One country has identified the potential need for interface standards between Smart meters and external
equipment such as displays and smart house control equipment including also dynamic price/tariff information.
This suggestion comes in recognition that customers might wish to respond to changes in electricity pricing
throughout the day. Although this potential requirement has been identified and the responder is aware that
some progress is being made in this area, it is not being studied in detail within their project.
