A technical convergence
The global energy transition, is fundamentally changing how power systems operate - and nowhere is this more visible, than at the distribution level.
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. - Bi-directional power flows introduce new coordination and protection challenges.
- Battery energy storage systems and EV
charging reshape demand patterns and
load behaviour.
- Inverter-dominated networks raise new
questions around grid-forming capability
and system resilience. - Digitalisation and online monitoring expand visibility, including into non-technical losses.
- 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
- The ability to integrate renewable generation at scale
- Customer participation and flexibility
- 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 ‘One Grid’ scope
To meet these dynamic needs, CIGRE’s work spans the whole power system across distribution, generation and transmission. Our global study committees span 16 key areas grouped into four key groups as shown below. Follow the links to learn more about each area.
