How does PV penetration affect a distribution system?

The severity of these issues depends on the penetration level of PV, configuration of distribution system and the location of PV in distribution system. In such cases, high level of PV penetration can inject power to transmission network which can affect the voltage level and protection setting of the distribution system.

Normally, the solar energy grid con- Table 2. Range of voltage at the PCC. c. If the frequency is 50.2 Hz, the solar power plant shall inject active power up to 51.5 Hz. operator and the owner of solar power plant. not exceed 10% (of the rated active power of the plant) per minute. quality of the voltage waveform at the PCC.

How is voltage quality affected by intermittency of PV power output?

Voltage quality can be affected by the intermittency of PV power output in distribution system . Generally, for PV generation type, climate changes can create irradiance fluctuations either for a short or long period of time. Therefore, this can affect the voltage output of PV in Point of Common Coupling (PCC).
