b'cired2021.orgSESSION 2:POWER QUALITY AND ELECTROMAGNETIC COMPATIBILITYSession 2 deals with all phenomena related to power quality (PQ). This includes flicker, unbalance and distortion in the frequency range up to 500 kHz. The session covers all aspects of electromagnetic compatibility (EMC) including emission, immunity and its coordination and standardisation. Conducted and radiated electromagnetic interferences as well as electric and magnetic fields (EMF) issues are also addressed. Specific focus is put on the PQ characteristic of modern power electronic devices and PQ challenges related to the operation of distribution grids with very high share of power electronics. Furthermore, new measurement techniques, analysis of big PQ data and the management of PQ at the interface between Distribution System Operators (DSOs) and Transmission System Operators (TSOs) are important topics for Session 2. Beside application examples and case studies, new modelling approaches and system simulation studies are covered.POWER QUALITY ELECTRIC AND MAGNETIC FIELDS, IMMUNITY AND SAFETY ISSUESIssues related to modern power electronic equipment, like storage systems and distributed energy resources, electricLow frequency electromagnetic interference, impact on vehicle charging, lighting devices, etc. metallic installations (pipelines, communication and power Issues related to future grids with very high share (up tolines)100%) of power electronics, including smart transformers Immunity issues related to smart meters, power line Challenges related to DC grids and microgrids, includingcommunication, ripple control systems and smartislanded operation electronic devicesPQ requirements for advanced distribution automationImpact of PQ on life time of equipmentschemes Standardisation aspects of immunityImpact of power electronics on resonances andNovel developments in EMF including simulation, frequency-dependent network impedance in themonitoring and standardizationfrequency range up to 500 kHz Mitigation techniques (shielding, active compensation)Calculation, estimation and assessment of emission limits Lightning and switching overvoltages and related Novel modelling approaches and simulation studies on PQ protectionStrategies to include PQ management in networkEarthing systems, step and touch voltages, neutral planning and operation grounding practices, risk evaluationMitigation techniques for PQ phenomena Safety issues in microgrids including islanded operationNeeds for the revision of PQ standards and EMC concepts driven by energy transition and climate change PQ ISSUES AT THE INTERFACE BETWEEN DISTRIBUTION Aspects of PQ regulation and benchmarking AND TRANSMISSION GRIDSCONTINUITY OF SUPPLY PQ management at the interface between DSO andTSO, including coordination of planning levels and Outages, interruptions and dips (statistics,emission limitsindices, etc.) Interactions related to windfarms, PV farms,Voltage dip immunity and ride through capabilityHVDC, FACTS etc.of grid-interactive inverters and converters Resonances related to long AC cables and increased Ride through solutions using new conceptscabling(e.g. synthetic inertia) Specific modelling and simulation issues, e.g. gridVoltage and frequency stability in islanded microgrids equivalent for harmonic studiesPQ MONITORING AND ANALYTICS New measurement techniques and indices, covering the frequency range DC to 500 kHzIntegration of PQ functionalities into secondary equipment, including smart meter, protection devices, etc.Efficient design and implementation of PQ monitoring campaignsStrategies for handling large amounts of PQ dataData mining and data analytics for PQ related data, including the application of AI techniquesNovel techniques for PQ data visualisationStandards for PQ data format and data interchange04'
