Power quality and supply reliability services for resilient grid operation

Power systems must deliver consistent, high-quality electricity to increasingly sensitive customers, even as supply variability and operational complexity grow. As renewable generation expands, electrification accelerates, and digital equipment becomes more common, maintaining power quality and supply reliability has become a core operational challenge for utilities and grid operators.

Fluctuating generation profiles, increasingly sophisticated customer equipment, and growing reliance on electronic devices are exposing networks to more frequent harmonics, voltage variations, flicker, and other disturbances. These developments are driving utilities to adopt more advanced approaches to monitoring, analysing, and mitigating power quality issues to maintain stable and efficient grid performance.

Addressing these challenges requires a clear understanding of the underlying causes, which can vary across industrial, commercial, and residential settings. Grid operators must determine how disturbances originate and propagate, assess their operational and safety impacts, and implement cost effective mitigation measures that align with regulatory requirements and customer expectations.

About DNV’s power quality and supply reliability services

DNV provides a suite of analytical and advisory services to help grid operators understand, diagnose, and improve power quality and supply reliability. Our technical assessments combine detailed modelling, measurement, and simulation to support confident decision‑making and effective mitigation planning. Our services include:

  • Harmonic analysis and mitigation: Identifying sources of harmonic distortions and implementing strategies to mitigate their impact on the grid and connected equipment.
  • Voltage dips and overvoltage solutions: Offering robust solutions to manage and prevent voltage fluctuations, safeguarding against equipment damage and operational disruptions.
  • Flicker measurement and mitigation: Analysing the causes of flicker and devising measures to minimize its occurrence, ensuring a stable and reliable power supply.
  • Reliability, Availability, Maintainability, and Safety (RAMS) assessment and enhancement: Utilizing advanced modelling and simulation tools to improve grid resilience, enhance supply availability, and facilitate flexible and optimal system operations.

These services can be complemented by root cause investigation, verification of mitigation measures, and ongoing support to maintain optimal grid performance.
