Current procedures and practices on grid code compliance verification of renewable power generation

Generation assets applying for grid connection must comply with certain grid code requirements. Grid code compliance verification shall include revision of documentation covering technical data and models, checking of requested capabilities, and validation of model performance. These procedures are singular regarding renewable power generation, due to their technical characteristics, specific topologies and short experience. This paper aims to carry out an updated review of the international regulations and current practices regarding the verification and certification of the electrical performance in renewable generation systems. Grid code compliance can be verified by practical tests or by simulation of validated models. Therefore, this paper also encompasses modelling and validation requirements, highlighting challenges caused by current procedures.
