159 Introduction
160 Over recent decades, energy production and its consumption patterns have changed dramatically. Although
161 central energy production is still dominant, the trend for distributed production is distinctive following an
162 increasing number of renewables. Alternative energy sources are highly fluctuating in their production
163 capabilities, which may result in the grid operators having difficulty to keep a balance between energy production
164 and consumption. The complexity of keeping the grid reliable is further increased by the change in the electrical
165 energy consumption and production of the customer itself, e.g. the use of electrical vehicles and personal
166 generation facilities.167 A Smart Grid that allows the grid operator to be flexible and reactive is needed. Such reactivity requires a
168 communication flow between energy consuming and producing entities, from single family houses to large
169 factories.170 The EN 50491-12 series describes aspects of the smart grid that relate specifically to the premises
171 (home/building) part of the smart grid and describes the common interface between equipment in the premises
172 and the smart grid. This part 2 of the series defines the fundamental aspects of semantic interoperability for the
173 S2 interface and the related data exchange between a CEM and the Resource Managers within the premises.
174 Different use cases are explained in Annex A, which should help to understand the philosophy of

177 This document specifies the fundamental aspects of semantic interoperability for the S2 interface and the related
178 data exchange between a CEM and the Resource Managers within the premises. It provides a technology
179 independent set of data models and interaction patterns in order to enable applications for Energy Management
180 within the premises. This document does not include:181 — mappings to concrete data representations (XML, JSON and similar);
182 — mappings to application protocols for the message passing;
183 — security related aspects.
