Industrial-process measurement, control and automation - Part 2: Internet of Things (IoT) - Application framework for industrial facility demand response energy management (IEC 62872-2:2022)

This part of IEC 62872 presents an IoT application framework for industrial facility demand
response energy management (FDREM) for the smart grid, enabling efficient information
exchange between industrial facilities using IoT related communication technologies. This
document specifies:
– an overview of the price-based demand response program that serves as basic knowledge
backbone of the IoT application framework;
– a IoT-based energy management framework which describes involved functional
components, as well as their relationships;
– detailed information exchange flows that are indispensable between functional components;
– existing IoT protocols that need to be identified for each protocol layer to support this kind
of information exchange;
– communication requirements that guarantee reliable data exchange services for the
application framework.

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.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

IEC 62872-2 has been prepared by IEC technical committee 65: Industrial-process
measurement, control and automation. It is an International Standard.
The text of this International Standard is based on the following documents:

INTRODUCTION

The World Energy Outlook 2017 [19] reported that industry consumed over 40 % of world

electricity generation in 2015. Furthermore, industry itself is a significant generator of internal

power, with many facilities increasingly implementing their own generation, co-generation and

energy storage resources. As a major energy consumer, the ability of some industries to

schedule their consumption can be used to minimize peak demands on the electrical grid. As

an energy supplier, industries with in-house generation or storage resources can also assist in

grid load management. For example, in-house generation can supply energy to the smart grid

and to the facility. Furthermore, storage resources can assist in smart grid load management.

While some larger industrial facilities already manage their use and supply of electric power,

more widespread deployment, especially by smaller facilities, will depend upon the availability

of a readily available standard interface between industrial automation equipment and the

"smart grid".

NOTE In this document "smart grid" is used to refer to the external-to-industry entity with which industry interacts

for the purpose of energy management. In other documents this term can be used to refer to all of the elements,

including internal industrial energy elements, which work together to optimize energy generation and use.

Standards are already being developed for home and building automation interfaces to the

smart grid; however, the requirements of industry differ significantly and are addressed in this

document. For industry, the planning of energy resources and production processes are under

the responsibility of the facility energy planner and production planner while operations are

under the responsibility of the facility energy operator and production operator.

Incorrect operation of a resource could impact the safety of personnel, the facility, the

environment or lead to production failure and equipment damage. In addition, larger facilities

may have in-house production planning capabilities which could be coordinated with smart grid

planning, to allow longer term energy planning.

IEC TS 62872-1:2019 defines the interface, in terms of information flow, between industrial

facilities and the "smart grid". It identifies, profiles and extends where required the standards

needed to allow the exchange of the information neede

125 FOREWORD

126 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

127 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

128 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

129 in addition to other activities, IEC publishes International Standards, Documents, Technical Reports, Publicly

130 Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is

131 entrusted to technical committees; any IEC National Committee interested in the subject dealt with may

132 participate in this preparatory work. International, governmental and non-governmental organizations liaising with

133 the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

134 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

135 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

136 consensus of opinion on the relevant subjects since each technical committee has representation from all

137 interested IEC National Committees.

138 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

139 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

140 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

141 misinterpretation by any end user.

142 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

143 transparently to the maximum extent possible in their national and regional publications. Any divergence between

144 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

145 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

146 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

147 services carried out by independent certification bodies.

148 6) All users should ensure that they have the latest edition of this publication.

149 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

150 members of its technical committees and IEC National Committees for any personal injury, property damage or

151 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

152 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

153 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

154 indispensable for the correct application of this publication.

180 INTRODUCTION

181 The World Energy Outlook 2017 [1] reported that industry consumed over 40 % of world

182 electricity generation in 2015. Furthermore, industry itself is a significant generator of internal

183 power, with many facilities increasingly implementing their own generation, co-generation and

184 energy storage resources. As a major energy consumer, the ability of some industries to

185 schedule their consumption can be used to minimize peak demands on the electrical grid. As

186 an energy supplier, industries with in-house generation or storage resources can also assist in

187 grid load management. For example, in-house generation can supply energy to the smart grid

188 and to the facility. Furthermore, storage resources can assist in smart grid load management.

189 While some larger industrial facilities already manage their use and supply of electric power,

190 more widespread deployment, especially by smaller facilities, will depend upon the availability

191 of a readily available standard interface between industrial automation equipment and the

192 “smart grid”.

193 NOTE In this document “smart grid” is used to refer to the external-to-industry entity with which industry interacts

194 for the purpose of energy management. In other documents this term can be used to refer to all of the elements,

195 including internal industrial energy elements, which work together to optimize energy generation and use.

196 Standards are already being developed for home and building automation interfaces to the

197 smart grid; however, the requirements of industry differ significantly and are addressed in this

198 document. For industry, the planning of energy resources and production processes are under

199 the responsibility of the facility energy planner and production planner while operations are

200 under the responsibility of the facility energy operator and production operator.

201 Incorrect operation of a resource could impact the safety of personnel, the facility, the

202 environment or lead to production failure and equipment damage. In addition, larger facilities

203 may have in-house production planning capabilities which could be coordinated with smart grid

204 planning, to allow longer term energy planning.

205 IEC TS 62872-1:2019 Industrial-process measurement, control and automation - Part 1: System

206 interface between industrial facilities and the smart grid defines the interface, in terms of

207 information flow, between industrial facilities and the “smart grid”. It identifies, profiles and

208 extends where required, the standards needed to allow the exchange of the information needed

209 to support the planning, management and control of electric energy flow between the industrial

210 facility and the smart grid.

211 “Internet of Things” (IoT) is being applied into different domains to facilitate the application.

212 Building on the system interface between industrial facilities and the smart grid defined in IEC

213 TS 62872-1:2019, this document addresses IoT application for industrial facility demand

214 response energy management (FDREM).The smart grid is a modern electric power grid

215 infrastructure system, whereby advanced information and communication technologies (ICTs)

216 are integrated with the power grid. Industry is the largest consumer of electricity among all end

217 user sectors. This has led to significant interest in the development of industrial energy

218 management around the world in recent years. Interconnectivity and interoperability are very

219 important features in the development of integrated energy management systems for industrial

220 facilities. Therefore, IoT technologies are needed and suitable for exchanging energy-related

221 information in FDREM. By using the IoT for communication, it enables real-time data-acquisition

222 (In this standard, it means acquisition of real time data, not data in real time.) and efficient data-

223 analysis, which can make industrial energy management more intelligent and cost-saving.

224 Currently, there may exist different implementation of IoT-based FDREM. Thus, a standard

225 specification is urgently needed to guide different kinds of IoT application to data-exchange in

226 industrial energy management.

227 The proposed IoT application framework is divided into the utility side and industrial electricity

228 demand side, with the utility meter as the boundary between the two. Functional components

229 that are essential for building the automatic demand response energy management are

230 described clearly in this framework. the IoT application framework is compliant with the IoT

231 Reference Architecture (IoT RA) standardized in ISO/IEC 30141, therefore, functional

232 components of the IoT application framework can be mapped to the IoT RA appropriately.

233 This document will also describe the functionality of each IoT protocol stack layers in regard to

234 communication of the IoT application framework, aiming to provide related information

235 exchange services for functional components. Identification of existing IoT protocols will be

236 executed to support this kind of information exchange. Non-functional communication

237 requirements will also be analysed to ensure comprehensive performance of the information

238 exchange.

239 Presently no standard covers industrial facility energy management with IoT technologies;

240 therefore this standard not only fills the gap to support such an IoT framework, but also can

241 guide the deployment of IoT into different energy management applications. For this purpose,

242 this standard will specify a general IoT-based communication framework for industrial FDREM.
