The rapid growth of renewable generation, distributed energy resources (DER), battery storage, and electric vehicles has shifted power systems from largely one-directional, predictable networks to highly dynamic, bi-directional systems. Distribution networks are no longer passive endpoints; they are becoming active participants in system operation.

As convergence occurs, CIGRE’s work transforms

As these technologies proliferate, technical boundaries that once separated planning, protection, power quality, and operations are dissolving. This means CIGRE’s work now encompasses many of the key issues affecting all players in the power system, including distribution. For example:

  • High penetration of solar PV, wind, and inverter-connected resources influence both power quality and system stability.
  • Inverter-dominated networks raise new questions around grid-forming capability and system resilience.
  • Bi-directional power flows introduce new coordination and protection challenges.
  • Digitalisation and online monitoring expand visibility, including into non-technical losses.
  • Battery energy storage systems and EV charging reshape demand patterns and load behaviour.
  • All of this unfolds within local regulatory frameworks, that must adapt to rapidly evolving technical realities.

Each of these developments affects the others and there are many more.

Distribution at the centre

This convergence is why distribution networks are a strategic component of power system evolution and a focus for CIGRE.

Decisions made at the distribution level increasingly influence:

  • System reliability and stability
  • Customer participation and flexibility
  • The ability to integrate renewable generation at scale
  • The effectiveness of broader transmission and generation strategies

As a result, distribution expertise, insight, and coordination are becoming critical to the successful operation and development of future power systems.

Our comprehensive scope

To meet these dynamic needs, CIGRE’s work spans the whole power system across distribution, generation and transmission. Our global study committees cover 16 key areas grouped into four key groups as shown below. Click the image to view our Study Committee home page
