09:00 - 10:30 Making T&D networks fit for wind integration
Integrating wind power into the electricity market  
Onshore      Offshore    

Room: Hall D

Distributed generation can offer clear benefits but also challenges for existing distribution systems. Wind and photovoltaic power from rural areas cause voltage fluctuations and over-voltages after disturbances. High-voltage ride through (HVRT) testing procedures, pilot projects, guideline and code drafting all help to address the HVRT requirement for distributed generation. Using smart components such as line voltage regulators and smart transformers, which include power-electronics and reactive-power compensation, are among other ways to stabilise distribution-level voltage. Applying International Electrotechnical Commission (IEC) standards, ensuring cybersecurity and deploying real-time data exchange communication between wind farms and the distribution system operator (DSO) can easily control and facilitate the integration of more wind power into distribution networks.

Learning objectives

  • Include the HVRT requirements into the grid codes;
  • Propose smart components with power-electronics to mitigate distribution-level voltage fluctuations and rises in rural areas, both by real experience and using simulations;
  • Enhance data exchange between wind farms and DSOs by ongoing standardisation and deployment of modernised and cyber-secure communication.


This session will be chaired by:
Vladislav Akhmatov, Senior Engineer, Emeritus Professor, Energinet, Denmark
