EU Commission publishes FGH study on the implementation of the RfG NC
EU Commission publishes FGH study on the implementation of the RfG NC

On behalf of the Directorate General for Energy – DG Energy – FGH has investigated how 35 countries implement the European Network Code of Requirements for Generators in their own national codes

Aachen. At the end of 2019, FGH received a tender from the EU Commission for a comprehensive study on the implementation of RfG NC. For one year, FGH-experts from the office in Aachen examined how individual countries have implemented the aforementioned framework and determined a level of convergence for the technical requirements.

Some technical requirements for grid connection of Power Generation Modules (PGMs) according to RfG NC were realised somewhat differently in each country. These diverging national implementations stem from the fact that the RfG NC gives grid operators and national regulatory authorities design freedoms for so-called non-exhaustive grid connection requirements. One of these freedoms is the categorisation of PGMs as type A to D. As an example, a PGM may already be considered type B in one country, but still count as type A in another. 

Additionally, the RfG NC formulates provisions for conformity testing and simulations in operational verification processes rather vaguely. Furthermore, some countries have already established concrete verification provisions, while others are working out verification processes and some have not implemented any procedures yet. Together this leads to a relatively broad spectrum of national implementation procedures today. 

“Those diverse requirements confront manufacturers, PGM project developers, and plant operators with significant market entry challenges”, says Mansoor Ali, head of the power generation technologies and grid components department at FGH. “Especially Manufacturers are challenged within the European internal market concept because they must take varying requirements for their products into account.” For project developers, electrical planning and grid code-compliant commissioning processes are crucial. During the operational period plant operators are responsible for ensuring grid code compliance in accordance with national regulations. Despite the uniform basis of the RfG NC these challenges are clear barriers to market entry within the European internal electricity market”, Mansoor Ali points out.

“Based on our comprehensive analysis, the study provides some recommendations on how a more uniform process could be established across Europe in the future”, concludes Bernhard Schowe-von der Brelie, Managing Director of FGH, who is involved in harmonising the rulemaking across various European and international committees.


FGH TURNS 100 YEARS
FGH TURNS 100 YEARS

01/25/2021 - On June 11, 1921, FGH was founded as Studiengesellschaft für Hochspannungsanlagen (SfH) in the still existing hotel "Schwarzer Bär" in Jena. Accordingly, FGH is very pleased to be celebrating its 100th anniversary this year.

While today FGH is one of the leading German companies in the field of security of supply of electrical grids as well as in the grid integration of renewable energies, in its founding year 1921, however, no one was thinking of broadly deployed extra-high voltage grids or even green power generation through wind power, biogas and photovoltaic plants. The task was to clarify grid faults on the first 110 kV lines centrally and to exchange experiences. Electrification progressed over the next 100 years despite the power grid transformation and all the changes it entailed.

To this day, FGH continues to uphold the aspiration it laid down in its 1921 statutes: The SfH - our present-day FGH - was founded as a research and testing institute. Its aim was to increase the efficiency and safety of electricity supply, to foster the exchange of experience between FGH members and to tackle new issues together with them. The association acted as a communication platform between network operators and equipment manufacturers. We as FGH are still pursuing and representing all of this 100 years later," explains chairman Dr. Andreas Olbrich.

 


FGH certifies largest solar park in Germany in Brandenburg
FGH certifies largest solar park in Germany in Brandenburg

One of three certified large-scale projects of the ENBW

12/01/2020 - By the end of the year 2020, Germany's largest solar park in Werneuchen is to be fully connected to the grid, which FGH certifies according to the new application rule VDE-AR-N 4120. The park has already fed the first kilowatt hour into the grid at the end of November 2020.
The project is being implemented without a feed-in tariff under the Renewable Energy Sources Act due to its size and the area it covers. Outside Berlin - in Weesow-Willmersdorf in Brandenburg - 164 hectares are available for this purpose. Since mid-March, Energie Baden-Württemberg (EnBW) has been building 465,000 photovoltaic modules with a total output of 187 megawatts. The southern German energy supplier is growing the park step by step in various construction phases.

FGH ANALYZES IMPACT OF E-MOBILITY ON GREEK DISTRIBUTION NETWORK

COOPERATION WITH GIZ CONTINUES

01/14/2020 - E-mobility is moving the world - and so is the FGH. From mid-May to the end of October 2019, it studied scenarios of different penetration rates of charging stations and electric vehicles into the Greek distribution network. The client was the GIZ (German Society for International Cooperation). In the process, the engineers derived suitable technical requirements, taking into account innovative approaches such as smart charging. Here, they drew on relevant expertise: FGH had already developed the meta-study "Research Overview - Grid Integration of Electromobility" on behalf of VDE | FNN and BDEW.

Research into new energy network structures for the energy transition

02/01/2020 - Phase II of the Copernicus project ENSURE started on February 1, 2020. The project takes a holistic approach to researching new energy grid structures for the energy transition. The focus is on clarifying how centralized and decentralized energy supply elements must be designed in the overall system. The feasibility of selected research results is realized in a grid technology demonstration, i.e. the practical implementation of the developed systemic concepts and the testing of new technologies take place.


GRID CONNECTION RULES IN EUROPE: FGH INVESTIGATES RFG-COMPLIANT IMPLEMENTATION
GRID CONNECTION RULES IN EUROPE: FGH INVESTIGATES RFG-COMPLIANT IMPLEMENTATION

01/29/2020 - The European Commission, Directorate General for Energy, has commissioned FGH to conduct a study. The topic: the implementation of RfG-compliant grid connection rules in Europe. Most member states have already published a final grid code. However, the implementation depends on various factors: e.g. the existing grid infrastructure, the share of distributed generation as well as renewable energy sources or the previous grid codes in the country.


FGH CERTIFICATION BODY TURNS 15
FGH CERTIFICATION BODY TURNS 15

09/09/2019 - In 2004, about 16,500 wind turbines provided an installed capacity of about 16.5 GW of electricity on the German mainland. Photovoltaic systems contributed 1.1 GW to the electricity mix.

Renewable energies were in their infancy and the certification body, as part of the FGH e.V., was still a kind of research project - initiated by grid operators and manufacturers of wind turbines to provide qualified, valid and independent verification for the then newly developed grid connection guidelines in Germany. After the first system-theoretical analyses and practical measurements in the mid-nineties, the FGH thus accompanied the development of renewable energies from the very beginning.
