Hi @ginoagb Übernimmst Du die Moderation der SGCP Funktionsprofile?

ginoagb commented 1 year ago

Hallo @ergozeller, ja danke. Ich kann die Moderation für den SGCP-Kanal übernehmen.

Use Cases und mögliche Funktionsprofile

Die Funktionenprofile des SGCP werden von einem Flexibilitätsanbieter (z. B. ein Energieversorgungsunternehmen, ein Anbieter für Flexibilitätspooling oder ähnliches) genutzt, um Produkte zu steuern, die SGCP-Profile unterstützen. Beispiele dafür sind Energiemanagementsysteme in Gebäuden, die wiederum Wärmepumpen, Ladestationen und Solaranlagen steuern.

Stufe 1:

Name Use Case FP Entwurf
Sperrsignal EVU Sperrsignal Kein Entwurf vorhanden
Stufe 2: Name Use Case FP Entwurf
Unidirektionales Flexibilitätslastmanagement Angewendet von Energie Thun ermöglicht es beispielsweise das Begrenzen, Sperren oder den normalen Betrieb von gesamten Parkplätzen mit Elektroladestationen. FP SGCP - UniDirFlexLoadMgmt #42
Unidirektionales Flexibilitäts-Einspeisemanagement Angewendet von Energie Thun ermöglicht es beispielsweise das Begrenzen, Sperren, Maximieren oder den normalen Betrieb der Rückspeisung entsprechend der Anlagemöglichkeiten. FP SGCP - UniDirFlexFeedInMgmt #43
EEG-Signal Gemäss dem EEG (Erneuerbare-Energien-Gesetz) müssen Photovoltaikanlagen in Deutschland grundsätzlich fernsteuerbar sein. Die genauen Anforderungen an die Fernsteuerbarkeit von Photovoltaikanlagen sind im EEG festgelegt und können je nach Anlagengrösse und Inbetriebnahmedatum variieren. Bei SmartGridready werden die vier Absenkungswerte zur Begrenzung der PV-Inverter-Rückspeisung evaluiert. Kein Entwurf vorhanden
S2 (Betriebsmodus-basierte Steuerung) Operation Mode based control aus CENELEC TC205 WG 18 Entwurf erst als Word File vorhanden bei @ginoagb
Stufe 3: Name Use Case FP Entwurf
Nichts vorhanden
Stufe 4: Name Use Case FP Entwurf
Bidirektionales Flexibilitätsmanagement Angewendet von Virtual Global Trading FP SGCP - BiDirFlexMgmt #41
Curtailment FP SGCP - Curtailment#44

Dazu für das Monitoring (Stufe .m):

Name Use Case FP Entwurf

Realtime Scheinleistung Echtzeit-Ablesung des Scheinleistungswerts FP NonSpecific - Frequency
Realtime Strom Echtzeit-Ablesung des Stromwerts FP NonSpecific - CurrentAC
Realtime Spannung Echtzeit-Ablesung des Spannungwerts kein Entwurf Vorhanden
Weitere untersuchte Standards: Standard Use Case
EN50491-12-2 EN50491-12-2 ist ein Standard, der sich mit der Kommunikation zwischen Smart-Grid-Geräten und Smart-Grid-Infrastrukturen beschäftigt. Speziell behandelt er die Interoperabilität von Smart-Grid-Geräten wie intelligenten Zählern, Heimenergiemanagementsystemen und anderen Geräten, die in einem Smart Grid verwendet werden. Der Standard definiert Protokolle und Anforderungen für die Kommunikation, um sicherzustellen, dass die verschiedenen Geräte nahtlos zusammenarbeiten können und eine effiziente Energieverwaltung ermöglichen. EN50491-12-2 legt grundlegende Regeln und Verfahren fest, um die Kompatibilität und Interoperabilität von Smart-Grid-Geräten zu gewährleisten und somit die Effizienz und Zuverlässigkeit des Smart Grids insgesamt zu verbessern.
IEC TC 57 WG 21 Working Group Technical Committee:
IEC TC 57 WG 17 Working Group Technical Committee: arbeitet an Microgrids
IEC SC23K WG3 Working Group System Committee: arbeitet auch am SGCP
IEC 61850-90-7 Defines communication protocols and data models for the automation of power substations and electrical grid systems. Curtailment (= the intentional reduction or limitation of electricity generation or consumption) parameters for the SGCP are taken from this standard.

During the KtS Meeting on 22nd September 2023, it was decided that an effort would be made to create an FP (Functional Profile) to cover the Groupe-E tariff "VARIO". The FP shall also be compatible with OpenADR 3.0 format.

Groupe-E tariff "VARIO":

Format:

Proposal for a new EEG Functional Profile

@d-spoerri-swistec

Referenced standard: "Netzanschluss für Energieerzeugungsanlagen an das Niederspannungsnetz (NA/EEA-NE7 – CH 2020)" and the EEG (Erneuerbaren-Energien-Gesetz) from germany.

The control of the EEA (EnergieErzeugungsAnlagen) by the VNB is mostly done using binary inputs. These are implemented as potential-free make contacts (Normally Open - NO). The VNB provides the technical specifications of the contacts (maximum voltage, maximum current).

And:

For the shutdown or reduction of the feed-in power, the control of the EEA must have at least the following binary inputs:

In practice, sometimes three relays or four relays (an additional one for 100% power) are used. However, normally, there should be four relays.

d-spoerri-swistec commented 10 months ago

Thanks Gino, this looks good. The mentioned VSE document also mentions that reactive power could be controlled using relays. However, this is hardly being used (right now), and many older inverters don't support controlling the reactive power ouput at all.

The control of active power, meanwhile, is very common in germany, and becoming more common in switzerland as well.

Ok, let's now concentrate on the most commonly utilized active power component for the functional profile. Additionally, we might consider creating a distinct functional profile for EEG reactive power to make it easier to differentiate between inverters that support reactive power control and those that do not.

Hi everybody,

I dont' know whether this issue was already discussed. Let me nevertheless bring it up:

In SGCP - UniDirFlexLoadMgmt, 2 components are addressed: the FlexManager in the Communicator role and the CEM in the Product role. A given datapoint is written - if you consider the Communicator role - and read - if you consider the Product role. To the best of my understanding, the profile definition takes the view of a Communicator, that's why the SGrFlexLoadIn1 and 2 datapoints are marked as W.

Is the above comment correct?

We should at least mention that the definition takes the point of view of the Product. We could also consider that the sgr specifications are mainly used by CEM developers. This would mean that all definitions takes the point of view of a CEM (i.e., in the particular case, the point of view of a Communicator).

Your position regarding this suggestion?

Functional Profiles always refer to the capabilities of a Product. In this case, the CEM is the Product, and the Flexibility Manager is the Communicator. Data points marked as 'Write' can be modified or influenced by the Communicator, while data points marked as 'Read' can be read by the Communicator. This approach is typically used in Modbus interface definition as well.

ChrisBroenni commented 10 months ago

In this case, the CEM ist the product as it is seen from distribution network's energy manager.

DEM <----> CEM <------> Device Client Server / Client Server

The current communicator defiinition in XSD does not seem to address this clearly. I'll start an issue there

dominiqu-gabioud commented 10 months ago

I agree that the approach "always present the view of a Communicator" is coherent. But in practice, the sgr profiles and software components will be mainlyused by CEMSsystem integrators. And a system integrator wil naturally assume that the documentation takes her/his view. This is exaclty what happens when our developer Michael Clausen read the documentation for th SGCP profile.

ChrisBroenni commented 10 months ago

IMHO this is a common way to show Interfaces in IEC and people get used to it. It's the same with KNX/BACnet/LonMark and Modbus documentations.

But I am also quite sure that one may find it the other way....

dominiqu-gabioud commented 10 months ago

Agree with @ChrisBroenni: mainly a question of definition/point of view and hence not worth a long discussion. Jut take care that the documention is clear.
