These introduce new power quality problems. Due to the switching power electronics, the grid voltage and current will contain, next to harmonic frequencies, an increasing content of power conversion harmonics in a frequency range up to 150 kHz and above. Moreover, both RES, grid connected inverters and loads comprise switching non-linearity’s with a non-negligible capacitive behaviour. Consequently, the behaviour of the grid evolves from resistive-inductive into resistive-capacitive, creating low impedance paths for the PCH. As a consequence, these harmonics circulate in the LV grid, causing several problems. https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/481b4ebd-97cc-4557-a9f6-99e7d49ec91d/filterconcept.png Work - Objective & Expected Results Development of innovative and robust filter concepts to mitigate HF interferences in the LV grid, taking into account PLC signals & non-linear loads, with the goal to improve the performance and reliability of the grid. Result 1: Models and tools to determine the impact of the grid components on the HF current emissions Result 2: HF PQ filter concepts tailored to handle HF disturbances under a changing grid impedance https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/94de91c3-b705-49ef-aabe-f55f8891fa2b/bluways_S.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/75d2e9cd-ad57-4177-8fa1-26c9f7b496a8/duco_S.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/9e03460d-e009-4dac-84c0-a751fd3e67c7/Logo_ducoop.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/87aadad2-0baf-4309-995c-ed7fa549a505/EngieLabor_S.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/5f60ea5a-308b-4192-802f-19206838ab6c/Fluvius_S.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/c2d9ac2b-9358-467c-9962-9482474431c6/Jema_S.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/eb2dd7f5-ea84-4e74-973e-2b7020a70cbf/S2Enso_S.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/c888e5d9-a800-4dd7-99ee-759e92e03ae0/Smappee_S.png Work https://images.squarespace-cdn.com/content/v1/61b74a4e91a8777f78bf56b6/7d2a2ebf-55ec-42db-bab8-1664e0d5a753/Yuso_S.png Work
