2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 9
EN 50549 intends to include all capabilities of generating plants necessary to operate generating plants in parallel to distribution grids
Therefore EN 50549-1 and -2 provides requirements needed for the stability of the interconnected system not yet included in RfG:
Robustness to voltage swells (OVRT),
Robustness to voltage sags (UVRT),
Recommended also for type A generators,
LFSM-U requirement,
explicitly required for EESS (Electrical Energy Storage Systems),
recommended for all other generating modules.
Framework and Scope
2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 10
EN 50549-1 and -2 scope excludes aspects of system integration:
Selection of point of connection,
power system impact assessment e.g. assessment of effects on power quality, local voltage increase, impact on line protections operation,
connection assessment, the set of technical verifications made as part of the planning of the connection.
These issues depend on the structure of the distribution grid and the management procedures of the DSO.

4 Conclusion
2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 18
Generating plants of type A and type B are mass market products
Example: In Germany more than 1,6 Million PV plants have been installed within the last 15 years.
Standardised
Requirements and
Compliance procedures are of high importance
to support efficient procedures for
generating unit manufactures,
generating plant developers,
distribution system operators.
How can EN 50549 support RfG implementation in a member state
2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 19
RfG does not foresee the support of harmonized standards, unlike regulations under the new approach
support to RfG depends on national implementation.
EN 50549 is the tool,
To become effective, the member state has to use it.
How can EN 50549 support RfG implementation in a member state
2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 20
EN 50549 is applicable for type A and B generating modules (mass market)
EN 50549-1 and -2 support the essential requirements of RfG (Title II)
EN 50549 -1 and -2 can be used as reference documents for the national implementation
EN 50549 -1 and -2 can be referenced by national documents clause by clause or as complete standard
If needed, parameters can be specified according RfG and used in EN 50549
Annex C can be used as template to publish national specification of non-exhaustive requirements
EN 50549-10 will support compliance process once in place

EN 50549 is written to be compliant and used in conjunction with COMMISSION REGULATION 2016/631 (RfG).
EN 50549-1 and -2 cover all technical (essential) requirements (Title II) of RfG applicable for type A and type B generating modules and as such will support technical requirements of RfG.
EN 50549 intends to include all capabilities of generating plants necessary to operate generating plants in parallel to distribution grids, therefore goes beyond the scope of RfG.
As RfG does not foresee the support of harmonized standards, support to RfG depends on national implementation of RfG.
EN 50549 -1 and -2 can be used as reference documents for the national implementation.

4 Conclusion
A1 Question regarding definition of “new power-generation module“
2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 24
RfG Article 7(4) requires relevant TSOs to submit a proposal for requirements two years after the entry into force, May 17th 2018.
RfG Article 7(6) requires the competent entities to decide upon the proposal within 6 month resulting in November 17th 2018.
As a consequence, connection requirements will be, in general, available following Nov. 17th 2018
Question regarding definition of “new power-generation module“
2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 25
RfG Article 3(1) requires all new power-generation modules to be compliant with RfG
RfG Article 4(2)(b) defines that a generating module shall be considered “existing” if the “main generating plant” has been purchased (binding contract) two years after entry into force of RfG, resulting in May 17th 2018
Some mass market technologies have only several weeks between conclusion of a binding contract and commissioning of the plant.
Typical main components such as inverter or uCHP units are on stock even before a binding contract is concluded.
As a consequence, first “new” power generating plants will be connected in June 2018, 5 moths before the connection requirements must be decided upon.
These power generating plants need to be updated before May 17th 2019
Question regarding definition of “new power-generation module“
2018-03-08 EN 50549 INTENT AND SCOPE THOMAS SCHAUPP / KACO NEW ENERGY 26
Possible solutions:
RfG Article 4(2)(b) last paragraph states:
A Member State may provide that in specified circumstances the regulatory authority may determine whether the power-generating module is to be considered an existing power-generating module or a new power-generating module.
Some member states use this statement to define existing power generating modules as:
Generators that have presented a complete request for connection to DSO before May 2019
Generators whose Power-Generating Module(s) was already connected to the DNO’s Distribution Network before May 17th 2019
Member states not having decided upon requirements until today should consider similar solutions.
