Internet of Things


et perspektiv fra Danfoss


Vores udgangspunkt som industriel virksomhed


Hvad laver internet i vores produkter i dag?


Udfordringer med øget connectivity.


Et par eksempler på igangværende forsknings og udviklingsprojekter

Fleksibelt energiforbrug


Upholding reserves in order to respond
instantly to quick changes in power
consumption represents cost of 1M DKK

The
Pain
!


Electricity cannot be stored in the transmission system, thus it is
generated at the same time as it is consumed


Consequently it is necessary to uphold reserves at all time in order to
respond instantly to unexpected changes in consumption. (short term
load variations <5min)


Cost of the pain:


Upholding these reserves represents unnecessary operational losses estimated
to 1.000.000 DKK (133k

) pr. MW annually, (Denmark)


For the global power generation industry the operational losses have a cost
annually of:
>14.000 M

Load variations


Power consumption

Fast variations in power consumption
(< 1min)

″Short term load variations″


Reserves are activated
within few seconds in order
to compensate for load
variations



Options for adjustment


Fuel adjustment

Condensate flow ctrl.



The thermal solution


Use thermal energy
storage as a buffer

Technical Approach


The eDIANA Platform is a reference model
-
based architecture,
implemented through an open middleware including specifications,
design methods, tools, standards, and procedures for platform validation
and verification. eDIANA Platform will enable the interoperability of
heterogeneous devices at the Cell and MacroCell levels, and it will
provide the hook to connect the building as a node in the
producer/consumer electrical grid.

Thus, eDIANA will provide a Reference Architecture for a network of
composable, interoperable and layered embedded systems that will be
instantiated to several physical architectures. The eDIANA Platform
realisations will then cope with a variable set of location and building
specific constraints, related with parameters such as climate,
Cell/MacroCell configuration (one to many, one to one etc), energy
regulations etc.

Expected impact


The technology to be developed in eDIANA will improve energy efficiency
and optimize buildings energy consumption by 25%, providing real
-
time
measurement, integration and control. Moreover, comfort will be
improved, making the user aware and enabling user
-
controlled policies
for household devices (lighting, domestic electronics, etc.).


Such progress beyond the state of the art will enable the building to
become an “active macroCell” in the energy network, connected to
similar macroCells in a district or urban area.

Konklusion


Hovedudfordringen for ”internet of things” er ikke at få tingene til at
snakke sammen, men at finde ud af hvad de skal snakke om.


Det er ikke trivielt at definere generelle middelware protokoller, specielt
på tværs af producenter og applikationer.


Der er mange projekter i gang, specielt mht. fleksibelt energiforbrug,
både på forsknings og udviklingsfronten.


Der er fokus på standardisering
