FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.

INTRODUCTION
Under the general title Generic smart grid requirements, the IEC SRD 62913 series consists
of the following parts:
– Part 1: Specific application of the Use Case methodology for defining generic smart grid
requirements according to the IEC systems approach;
– Part 2: is composed of five subparts which refer to the clusters that group several domains:
• Part 2-1: Grid related domains – these include transmission grid management,
distribution grid management, microgrids and smart substation automation;
• Part 2-2: Market related domain;
• Part 2-3: Resources connected to the grid domains – these include bulk generation,
distributed energy resources, smart home / commercial / industrial / DR-customer
energy management, and energy storage;
• Part 2-4: Electric transportation related domain;
IEC SRD 62913 refers to 'clusters' of domains for its different parts so as to provide a neutral
term for document management purposes simply because it is necessary to split in several
documents the broad scope of smart grid.
The document for each domain is composed as follows.
• Purpose and scope.
• Business analysis: to address domain’s strategic goals and principles regarding its smart
grid environment. It also lists business use cases and system use cases identified, their
associated business roles and system roles (actors) and the simplified role model
highlighting main interactions between actors.
• Generic smart grid requirements: extracted from Use Cases described in Annex B.
• Annex A lists links between domains, technical committees and gathered materials
(existing standardization documents, user stories, Use Cases and functional architectures).
• Annex B includes a complete description of Use Cases per domain based on IEC 62559-2.
• Bibliography.
The purpose of this document is to define the generic smart grid requirements of the market
related domain, based on the methods and tools developed in IEC SRD 62913-1.
This analysis is based on the business input from domain experts as well as existing material
on grid management in a smart grid environment when relevant. Table 1 highlights the
domains and business use cases described in this document.

GENERIC SMART GRID REQUIREMENTS –

Part 2-2: Market related domain

1 Scope
This part of IEC SRD 62913 initiates and illustrates the IEC’s systems approach based on
Use Cases and involving the identification of generic smart grid requirements for further
standardization work for market related domains, based on the methods and tools developed
in IEC SRD 62913-1.
It captures possible “common and repeated usage” of a smart grid system, under the format
of “Use Cases” with a view to feeding further standardization activities. Use Cases can be
described in different ways and can represent competing alternatives. From there, this
document derives the common requirements to be considered by these further standardization
activities in terms of interfaces between actors interacting with the given system.
To this end, Use Case implementations are given for information purposes only. The interface
requirements to be considered for later standardization activities are summarized (typically
information pieces, communication services and specific non-functional requirements:
performance level, security specification, etc.).

4 Market
4.1 Purpose and scope
4.1.1 Clause objective
The purpose of Clause 4 is to present a business analysis of the market domain in a smart
grid context, and more specifically to describe the smart grid requirements of the domain
using the generic Use Case approach as defined in [1] . This analysis is based on a
European perspective, and will need to be extended to other regions (such as North-American
markets).
4.1.2 General context
4.1.2.1 General
Two technological trends are impacting the electric power system:
• the development of distributed renewable energy sources, which are intermittent;
• the development of smart grid technologies.
4.1.2.2 An electric power system perspective – the need to strengthen the
management of balance between demand and supply through interconnected
transmission grids
The functioning of the electric power system requires maintaining the balance between supply
and demand at any time, in order to avoid situations leading to load shedding or even
blackouts, which could have dramatic economic consequences.
The electric power system, in which balance between demand and supply is managed at the
level of transmission networks by the TSO, provides the following benefits.
• It contributes to ensure security of supply and cost optimization to the benefits of
consumers, by reducing and localizing the impacts of faults and other unexpected events,
and by using the most efficient generation capacities at each synchronous area at first and
if not existing at the national level.
• It offers a better use and increases the value of intermittent renewable energy sources, by
mitigating their variations (see for example North-South grid interconnections in Germany).
• It allows solidarity between regions which have high penetration of distributed renewable
energy sources and others with lower shares of renewable energy sources.
To ensure the reliability of the electric power system, stakeholders can rely on the following
key players:
Numbers in square brackets refer to the Bibliography.

• regulated actors, like system and grid operators, who manage the networks and ensure
physical balance between production and consumption in their balancing zone for system
operators;
• deregulated actors (such as suppliers/retailers, flexibility aggregators, producers, or
electricity traders/brokers), who operate within a balancing zone, on which balance
responsible parties have a financial responsibility.
4.1.2.3 Evolutions needed for the electric power system
4.1.2.3.1 A need for more flexibilities
First, the development of renewable energy sources, more particularly wind and solar power,
increases the variability and uncertainties on balance between supply and demand. The
electric power system will need more flexibility to maintain this balance and further face new
challenges.
A global cost benefit analysis (CBA) should be achieved to assess the economic relevance of
the flexibility versus grids developments.
4.1.2.3.2 New constraints in distribution networks
The increased penetration of distributed generation from renewable energy sources into
distribution and transmission networks tends to generate operational problems. The risk to
violate grid operational constraints increases.
Grid operators have traditionally managed these constraints in the long term with network
reinforcement, investments, and in the operational time horizon by switching actions,
emergency control of customers and, if other means fail, by disconnection of less critical
feeders and customers.
Otherwise the result is an uncontrolled wider and longer nonselective blackout.
A more dynamic management of the grid would allow grid operators to optimize network
investments and to reduce the risk of blackouts and a loss or limitation of customers’ physical
access to the market.
With the increasingly dynamic power flows, it also becomes necessary to take into account
the dynamic grid constraints in the electricity markets in a fair and transparent way.
4.1.2.3.3 Expected benefits of smart grid technologies on flexibilities and network
management
Furthermore, smart grid technologies, including the deployment of smart metering systems for
residential and business customers and communicating electrical equipment, will enable the
development of further flexibilities and contribute to the reliability and efficiency of the electric
power system.
These flexibilities, which can be defined as a modification of injection and/or extraction on an
individual or aggregated level, in reaction to an external signal in order to provide a service
within the energy system, may be traded within the electricity market, to deliver ancillary
services, services to grid operators, for the TSO for balancing purposes, or to allow an
optimization of production costs for instance.
Flexibilities can be incentivized and remunerated by:
• a variation of electricity prices (purchased or supplied),
• a variation of network tariffs,
• a direct compensation for the provider of the flexibility.

– 10 – IEC SRD 62913-2-2:2019 © IEC 2019
Furthermore, the activation of localized flexibilities (injection or extraction) can allow system
and grid operators to solve specific grid constraints. These local flexibilities, developed by
actors within their balancing zone, impact the balance between supply and demand and
therefore have to be taken into account in its management at a system level.
Table 2 lists some examples of flexibility products based on active demand, as well as their
main characteristics.
Table 2 – Examples of flexibility products based on active demand
Active demand Conditionality Typical example
product
Bi-directional conditional Conditional (real Having the capacity to provide a specified demand
re-profiling option) modification during a given period in a bi-directional range
[y, x] MW, including both demand increase and decrease.
The delivery is called upon by the buyer of the active
demand product (similar to a reserve service).
Conditional re-profiling Conditional (real Having the capacity to provide a specified demand
option) modification during a given period. The delivery is called
upon by the buyer of the active demand product (similar to
a reserve service).
Scheduled re-profiling Unconditional Obligation to provide a specified demand modification
(obligation) (reduction or increase) at a given time to the product
buyer.
The business analysis of the market domain will detail how these flexibilities can be provided
and used by various roles of the electric power system within the electricity market.
4.1.3 Overview of electricity market
The purpose of electricity market is to allow actors of the electric power system to purchase
and sell energy and energy-related products and services. Trading can take place:
• on stock exchanges – such as EPEX Spot for instance;
• via mutual agreement (direct or brokered).
Even though the domain is referred to as “market” in the singular, it is more accurate to speak
about “electricity markets” in the plural. Indeed, separate marketplaces or market mechanisms
with specific sets of rules, roles, and objectives may exist in the same zone and even be
coordinated.
The business analysis of the domain focuses on the flexibility products and services traded
within electricity markets which allow market players to execute/enable their business
processes. These internal processes are out of the scope of this document.
4.2 Business analysis
4.2.1 General overview
The electricity markets are going to have a preponderant place for the whole electric power
system. The development of new electricity usages and the integration of DER need reliable
and efficient market mechanisms. To contribute to the security of the system and to obtain the
best deals between market participants, the development of market facilities, market products
and a better cooperation between actors are required.

Flexibility products and services may be traded within existing or new markets and market
mechanisms – depending on various elements such as legal rules, the time scale or
geographic scale.
Here are some major improvements expected for the main domain business roles from the
integration of flexibility products and services within electricity markets.
• End-customers may benefit from better energy supply contracts and reduced electricity
bills if they accept to modulate their consumption and participate in the market (via a
supplier, a flexibility aggregator/operator, or another third party).
• Suppliers will be able to propose to their customers flexible offers and create value with
attractive tariffs, by developing active demand offers combined with competitive tariffs
during off-peak periods and/or less competitive tariffs during peak periods for instance.
This flexibility can create value on energy markets or allow system or grid operators to
solve network constraints. Suppliers may also participate in a capacity market or
mechanism – when such a market/mechanism has been implemented.
• Flexibility aggregators will develop, offer and manage various flexibility products and
stakeholders for grid users (consumers, producers, and/or prosumers), system operators,
or grid operators.
• System operators and grid operators may obtain (new) flexibilities to ensure the network
reliability, plan work programmes and ultimately realize investments – as long as these
flexibilities meet certain requirements according to the legal framework.
• Producers may rely on new levers to sell their production, plan their investments and
works, and self-insure against business risks – by buying flexibilities.
A strong coordination between certain roles will be needed to prevent market side effects and
ensure the overall optimization of the system. More specifically, Transmission system
operators and grid operators may have to reinforce their cooperation to prevent situations
where their actions on a given network would generate unacceptable constraints on another
network, or situations where they compete for the same products. Different models may be
proposed, with shared portfolio or separate markets/mechanisms for instance. These models
should be assessed through a global analysis taking into account all the aspects of the
system to select the most economically efficient option, complying with the legal framework.
Regarding the potential use of flexibilities by system and/or grid operators, the following
points should be noted.
• Local flexibilities obtained by grid operators may benefit the overall electric power system,
provided that the benefits for the grid exceed their costs (additional energy costs,
management costs, loss of opportunity, etc.). Regulation mechanisms would have to be
implemented to manage the activation and ex-post certification of such flexibilities. Grid
operators may have to pay compensations for their use.
• Several ways to request local flexibilities may exist; grid operators should be incited to use
the most cost-efficient ones.
• Flexibility price signals should combine their value for the grid and their value for the
market. Flexibilities exist in limited number. A strong coordination between flexibilities
activated for grid purposes and flexibilities activated for market purposes should therefore
be targeted, in order to avoid reducing their value and as a result the incentive for the
customer.
It is proposed that the focus of the market should be the support of power system
stakeholders’ activities via the use of flexibilities in marketplaces. Several new and evolving
business processes are proposed in 4.2.2, and could be described as business use cases.
4.2.2 List of business roles and business use cases of the domain
The business use cases listed are a result of the business analysis carried out previously –
the list is not exhaustive, and it is likely to grow as new Use Cases come to light.

A.2.2 Gathered materials
A.2.2.1 General
Concerning standardization, it seems interesting to refer to IEC SG 3 (Strategic Group on
Smart Grid) general recommendation on Markets. SG 3 worked together with IEC SyC Smart
Energy to progressively gather smart grid requirements information with a single method,
within a single framework, based on Use Cases, and then enable standards to be developed
in harmony, and incrementally match the moving market expectations. The IEC Smart Grid
Standardization Roadmap [3] states that in the electricity market domain, electrical energy is
purchased and sold as a commodity. The price of electrical energy is set by supply and
demand. In future domains, market and price information will be distributed to a larger extent
and to participants in the domain which do not today receive price and market information.
Information must be distributed online and within a far shorter time period than today. Pricing
information at the consumer site may be available on an hourly or even shorter basis. The
relevant standards are not within the scope of the IEC.
The IEC Smart Grid Standardization Roadmap states:
“The IEC should seek close cooperation with stakeholders in the domain “markets”. A lot of
proprietary work is done in that field. The IEC should seek close cooperation with
organizations such as UN/CEFACT and UN/EDIFACT as well as other important regulatory
authorities and trade associations. An investigation of the most promising market data
systems must be performed. This input is vital for an extension of the smart grid with market
information.” Recommendation G-4

NOTE Many works have been undertaken to address market related communication, especially in the IEC 62325
series [4]. Many parts are also to come. This series is the result of large worldwide co-operation between
stakeholders. Its structure allows creating region-specific profiles and its acceptance is already very encouraging.
This series is now part of the set of smart grid core standards.
