What if a minimum customer load coincides with high PV generation?
There may be some instances when a minimum customer load coincides with high PV generation, such as during a midweek summer holiday. The mitigation for this potential problem is to replace the distribution transformer with one that can carry the entire PV output while the customer load is near zero.
What are PV impact thresholds?
The specific PV impact thresholds for each distribution utility are likely to be dependent on typical design standards and operation practices. Traditionally, the distribution system has been designed to operate in a radial fashion, with flow in one direction from the substation source to the load.
How do high penetrations of PV affect circuit voltage?
High penetrations of PV can impact circuit voltage in a number of ways. Voltage rise and voltage variations caused by fluctuations in solar PV generation are two of the most prominent and potentially problematic impacts of high penetrations of PV.
How can a high-voltage PV system be mitigated?
Mitigation measures include running the PV at an absorbing power factor, which may negate needs for circuit reactive compensation. Use of line-drop compensation can be considered if the flow through is not masked. Modifying switch capacitor bank controls is another method that can be used to resolve high-voltage issues.
