A large part of the newly installed generators will be connected to the power system through inverters and electronic converters, whose behaviour differs from the generators connected synchronously to the network. One of the main differences is the current contribution during symmetrical and asymmetrical faults which can affect protection systems. New grid codes establish requirements for fast current injection, but the converter’s maximum current limitations during faults make it difficult to establish control strategies for such current contribution. This paper studies the performance of faulted phase selector algorithm of a commercial relay under the current contribution from renewables before unbalanced faults. Two positive and negative sequence current injection strategies in compliance with new Spanish grid code requirements are proposed and tested under fault conditions in HiL (Hardware in the Loop). Test results show that the selected injection strategy affects the fault phase identification algorithm. Furthermore, the negative sequence injection requirements established in the new grid code improve the relay performance when line-to-line faults are applied, but they are not enough to identify all fault types. info:eu-repo/grantAgreement/EC/H2020/864579/EU/Interoperable solutions for implementing holistic FLEXIbility services in the distribution GRID/FLEXIGRID This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 864579-FLEXIGRID info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.2 2022 ENERGY & FUELS 80 / 119 = 0.672 2022 Q3 T3 0.632 2022 Engineering (miscellaneous) 2022 Q1 Electrical and Electronic Engineering 2022 Q2 Energy (miscellaneous) 2022 Q2 Renewable Energy, Sustainability and the Environment 2022 Q2 Fuel Technology 2022 Q2 Control and Optimization 2022 Q2 Energy Engineering and Power Technology 2022 Q2 5.5 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Comech, Maria Paz Universidad de Zaragoza (orcid)0000-0002-4133-7553 Martinez Carrasco, Eduardo Prada Hurtado, Aníbal Antonio 5009 535 Universidad de Zaragoza Dpto.
