Utility-Scale Solar PV and Distribution Voltage Challenges - Self Study
About this 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.
