Definition
Power quality describes the degree to which the voltage in the electricity grid meets the requirements of consumers and producers - including nominal voltage level (230 V/400 V), frequency (50 Hz), deviation from a smooth sinusoidal waveform (harmonics), flicker and voltage drops. Poor power quality can damage electrical equipment, disrupt industrial processes and trigger protection relays. NVENorway's Directorate of Water Resources and Energy - regulates the electricity and water resources sectors. regulates power quality through the KILEQuality-adjusted Revenue (Kvalitetsjustert inntektsramme) - economic regulation where grid companies are penalised for power outages based on their cost to customers. scheme. With more distributed generation (solar energyElectrical energy produced from sunlight via solar panels (PV installations)., electric vehicle charging), the challenges of power quality in the distribution network are increasing.
