34、art 12-4: Resource manager BS EN 50491121:2018EN 50491-12-1:2018 (E) 4 Introduction Traditional electricity networks make use of a primarily one-way flow of energy and communication from the generator to the consumer via the transmission and distribution systems. Although there is some monitoring an
35、d control of equipment in the transmission and distribution systems, there is no communication with, or control of, consumer equipment. In particular, there is no means of requesting short-term control of consumer equipment according to generation and/or transmission/distribution grid conditions. Ge
36、neration equipment is controlled according to the open-ended (uncontrolled) demand of the consumer. Today we are faced with an increase of energy consumption, this is directly connected to an increase of CO2 production. The increased CO2 density in the atmosphere supports the climate warming of the
37、earth. One significant way to cope with the increased energy consumption without increasing the CO2 production is to use more renewable energy resources. Unfortunately, the available renewable energy supply is not aligned with the energy demand. To increase efficiency, the energy demand should be al
38、igned as much as possible with the available energy supply. To reach this goal communication between the various equipment and systems of the stakeholders within the energy field is necessary. This grid, exchanging information and energy between producers, consumers, distributors and metering is kno
39、wn as the “Smart Grid”. The EN 50491-12 series describes aspects of this smart grid that relate specifically to the premises (home/building) part of the smart grid, including the common interface between equipment in the premises and the smart grid. BS EN 50491121:2018EN 50491-12-1:2018 (E) 5 1 Scop
40、e This document specifies General Requirements and Architecture of an application layer interface between the Customer Energy Manager (CEM) and Smart Devices (SD) operating within the smart grid premises-side system (i.e. home or building but not industrial premises). This document does not include
41、requirements for: Safety; EMC; Data security; it is assumed that the underlying protocols will take the data security aspect into account; NOTE Although data security is not within the scope of this standard, in Clause 4 some high-level design guidelines for data security are provided. Special equip
42、ment (e.g. legacy heat pumps) with a direct physical connection to the grid, as such equipment bypasses the CEM and is not HBES/BACS enabled (covered by other standards than the EN 50491 series). 2 Normative references The following documents are referred to in the text in such a way that some or al
