This document specifies the fundamental aspects of semantic interoperability for the S1 interface and the related data exchange between Energy Management Gateway and the BEM / CEM within the premises. It provides a technology independent set of data models and interaction patterns in order to enable communication between Energy Management Gateway and BEM / CEM for applications where physical driven energy curtailments for the premises must be taken into account. This document does not include: - mappings to concrete data representations (XML, JSON and similar); - mappings to application protocols for the message passing; - security related aspects.
Over recent decades, energy production and its consumption patterns have changed dramatically. Although central energy production is still dominant, the trend for distributed production is distinctive following an increasing number of renewables. Alternative energy sources are highly fluctuating in their production capabilities, which may result in the grid operators having difficulty to keep a balance between energy production and consumption. The complexity of keeping the grid reliable is further increased by the change in the electric energy consumption and production of the customer itself, e.g., the use of electric vehicles and personal generation facilities.
A Smart Grid that allows the grid operator to be flexible and reactive is needed. Such reactivity requires a communication flow between energy distribution operators and premises, from single family houses to large factories.
The IEC 64302 series describes aspects of the smart grid that relate specifically to the premises
(home/building) part of the smart grid and describes the common interface between smart grid and the
premises. This part 2-1 of the series defines the fundamental aspects of semantic interoperability for the S1 interface and the related data exchange between a DSO and premises.
Different use cases are explained in Annex A, which should help to understand the philosophy of IEC 63402-2-1
