6 FAQs about [Solar power generation shows undervoltage]
Why is roof-top solar photovoltaic (PV) booming as a distributed generating system?
Due to low maintenance cost, learning ability, market growth and nascent technologies, the roof-top solar photovoltaic (PV) technology is booming as a distributed generating system. The voltage profile of the distribution grid is improved by solar power generation (SPG) coupled voltage source converter (VSC) at common coupling point (CCP) [ 2 ].
What are overvoltage and undervoltage events?
Overvoltage events for various PV penetration levels. Undervoltage events occur during the evening high demand period, when PV generation is mostly unavailable, especially during the winter months when the sun sets at around 5 p.m.
What is photovoltaic (PV) generation?
Photovoltaic (PV) generation is a form of distributed generation that is being deployed very rapidly. Despite many benefits, such as reducing power distribution losses, improving voltage profile, and solving environmental problems, the PV penetration also imposes many challenges (Baran & El-Markaby, 2005).
How does overvoltage affect PV generation?
At this level of penetration, the overvoltage events cause nearly a thousand ‘nominal voltage violation’ instances at the inverters leading to at least 625 MWh of PV generation loss due to inverter disconnections. For the customers, this represents an annual financial loss of over $106,000 due to the loss of energy export revenue.
How many undervoltage events are observed?
The time frame of the observation is half-an-hour, which means 25 undervoltage events observed for the current PV penetration is equivalent to 12.5 h of undervoltage in the year 2018. For 40% additional PV, the number of undervoltage events reduces to 15, a 40% reduction from that for the existing penetration level. Fig. 8.
Does solar PV reduce power demand?
Although solar PV system can efficiently reduce the demand, the apparent power does not decrease. The pf is maintained as 0.9 after the connection of the PV system and becomes sta-ble. This is attributed to the high level of solar irradi-ance that occurs during the daytime, which produces more power.
