Solving this problem is crucial to guarantee the reliability and stability of the power system. Current standards force the generators to remain connected when facing voltage and/or frequency disturbances and, in some advanced grid codes, also when the generators are facing transient phase jumps produced as a consequence of those disturbances. If considering that the increment of the distributed generation is mainly done at a distribution level, it is unrealistic to consider voltage and frequency events as decoupled phenomena in the testing and certification procedures, as it is currently done. The testing device proposed in this paper is able to reproduce voltage, frequency and phase jumps disturbances of a controlled value simultaneously, being able to reproduce the real grid behavior reliably. Its design is based on standard components with a simple control system, which makes it easily replicable and scalable up to the power of the device to be tested. Therefore, the proposed device is an interesting commercially competitive testing equipment suitable for certification.121552528enginfo:eu-repo/semantics/restrictedAccessjournal article10.1016/j.ijepes.2017.12.030Distributed generation testing equipmentElectrical disturbances generatorInduction regulatorVariable frequency transformerDistributed generation testing equipmentElectrical disturbances generatorInduction regulatorVariable frequency transformerEnergy Engineering and Power TechnologyElectrical and Electronic EngineeringFunding InfoThis work has been funded by the Spanish Ministry of Economy and_x000D_ Competiveness under research grants PN-ENE2009-13276 and BES-_x000D_ 2010-034386.This work has been funded by the Spanish Ministry of Economy and_x000D_ Competiveness under research grants PN-ENE2009-13276 and BES-_x000D_ 2010-034386.http://www.scopus.com/inward/record.url?scp=85040035539&partnerID=8YFLogxK
