Distributed Generation

Small and medium generating resources located closer to loads than traditional central stations.

Electrical safety boundary: this page explains the system conceptually. It does not provide procedures for live electrical work, switching, protection settings, conductor/breaker sizing, substation access or high-voltage operation. Those activities require qualified professionals, applicable codes and utility procedures.

Where this fits

Small and medium generating resources located closer to loads than traditional central stations.

Core system ideas

Distributed generation can include rooftop solar, small generators, combined heat and power and other local resources.

Local generation changes the direction and variability of power flow on distribution networks.

Interconnection, protection, voltage control and visibility become more important as penetration rises.

Interfaces and tradeoffs

Modernization layers sensing, communications, software and power electronics onto the physical grid. Those additions create new capabilities as well as lifecycle, interoperability and cybersecurity dependencies.

What organizations measure

Local output, export/import, voltage, hosting capacity and curtailment.
