ISGT Europe 2018 - Power quality challenges and solutions in transmission networks with high penetration of power electronics –interim results of EU H2020 MIGRATE

One of the focuses of the Migrate project is the evaluation of power quality (PQ) issues expected in future transmission networks due to high penetration of power electronic (PE) devices. PE devices, such as PE-interfaced wind generators, FACTS devices and HVDC links, are indeed one of the major sources of network disturbances (harmonics, flicker, voltage and frequency variations), while also being very sensitive themselves to PQ disturbances. The goal within the Migrate project is to propose a methodology for the evaluation of PQ levels in future power networks, where a high-share of PE devices is expected. The addressed topics include PE-device simulation models for PQ studies at transmission level, PQ measurements with PMUs and a probabilistic methodology for the assessment of disturbance propagation.
