Free Course – Utility-Scale Solar PV and Distribution Voltage Challenges

Approved for 1 NABCEP CPU!

Summary: The application of high penetrations of solar PV on utility distribution feeders can create challenges for the distribution organization to supply acceptable voltages on the feeder. As a result, the distribution organization may require voltage issue mitigation measures, including feeder infrastructure improvements, to be performed before additional solar PV capacity can be installed on a feeder. The solar PV developer usually has the responsibility to fund at least part of the improvements.

The following topics are covered in this FREE beginning-level technical course:

  • Overview of a utility distribution feeder and the utility’s responsibility to provide adequate voltage for all customers.
  • Types of voltage issues that can be created by utility-scale solar PV
  • Typical voltage mitigation measures that have been applied
  • A brief description of smart inverters which are now being applied in some states/jurisdictions and have demonstrated a number of capabilities, including voltage regulation and voltage ride-through for system events
  • Hosting Capacity Analysis, which a number of states are now requiring from utilities. Hosting Capacity Analysis gives an indication of the amount and location of solar PV that can be placed on feeders without violating specific operating constraints on the feeders, including acceptable voltage ranges and deviations.

Intended Audience: Anyone that needs an understanding of voltage issues that Solar PV can create on utility distribution system, including people who work for:

  • Utilities, municipalities, and co-operatives
  • Solar developers and engineers
  • Equipment and software vendors
  • Consultants and policy/research organizations
