Abstract

The EU regulation Requirements for Generators (RfG) was fully enforced in Sweden in April 2019. With RfG, which contains requirements on the grid connection of new power-generating modules (PGMs), the EU aims to ensure a continuous market integration within the union, increase the security of supply and facilitate a continuous integration of renewable energy production. With the purpose of ensuring that the capabilities required in RfG are installed in new PGMs, compliance with the requirements must be shown before commissioning a new PGM via either on-site test, simulations or both. However, the information RfG provides regarding how compliance is to be shown is vague. This has introduced ambiguity to the Swedish electricity sector with regards to what is required to show compliance. Therefore, in this study, an investigation of the Swedish compliance landscape with regards to RfG has been performed, with the objectives of shining light on obstacles that relevant actors in the industry experience and examining which incentives they have to comply with RfG today. Furthermore, the study gives a contribution to how compliance can be shown via templates of simulations for the requirements on wind power parks with a cumulative installed power of 10 MW to have the capability of delivering frequency regulation. The results indicate that the industry needs procedures of best practice, further guidelines or rules with regards to how compliance is to be shown to be able to achieve cost-effectiveness. Moreover, the templates provided in the study illustrate what types of guidelines that are demanded.
