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

180 INTRODUCTION
1
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.
