Report-on-proposed-DCPQ-parameter-definitions-for-LVDC-grids

Within the context of the project “Standardisation of measurments for DC electricity grids’’ (20NRM03 DC grids, see https://dc-grids.nl), the University of Strathclyde, INRIM, CIRCE, EDF, TU-E, and VSL leveraged draft DCPQ parameter definitions. This collaborative endeavor culminated in a detailed report that represents a significant contribution to the field of DC power quality (DCPQ). It encompasses two primary elements: Firstly, the report formulates a precise definition for DCPQ, encapsulating the essential parameters and metrics crucial for evaluating the quality of DC power in distribution systems, thereby distinguishing it from traditional AC power quality standards based on previous reports. Secondly, it proposes detailed characteristics of Low Voltage DC (LVDC) voltage disturbances to be considered in future revisions of the EN50160 standard, including types, magnitudes, frequencies, and durations of disturbances, based on extensive research, simulations, and field measurements. Drawing upon the collective expertise of stakeholders and incorporating findings from various experiments, this report serves as a foundational resource for advancing the standardization and reliability of public DC power systems.
