An emerging network enhancement, Soft Open Points (SOPs), has been investigated to bring flexibility to the overall Low-Voltage (LV) network. The utilization of Power Electronics Devices (PEDs) in the form of SOP accommodates the increases in load and connected distributed generation (DG), meanwhile supporting grid operations with supplementary functionalities. However, owing to its designated operation and unique topology, there are challenging issues in its practical implementation. This paper investigates the ever-challenging Electro-magnetic Compatibility (EMC) issues resulted from the unbalanced operation of SOP. Two novel approaches have been proposed to tackle the issue. The feasibility and performance of the proposed solutions are verified through mathematical derivations and extensive simulation studies.
