6 FAQs about [Reactive power compensation for solar power plant]
What is reactive power compensation in solar PV inverter?
Reactive power compensation is provided only when active power generation by solar PV inverter decreases abruptly. This helps in maintaining a smoother PCC voltage profile. This would subsequently result in reduced number of tap change.
What are the benefits of reactive power provisioning in a photovoltaic system?
Photovoltaic (PV) system inverters usually operate at unitary power factor, injecting only active power into the system. Recently, many studies have been done analyzing potential benefits of reactive power provisioning, such as voltage regulation, congestion mitigation and loss reduction.
Can reactive power compensation be used in grid connected PV inverters?
To validate this scheme, simulation is carried out with grid connected PV inverters at the distribution level with different levels of reactive power compensation. It is shown that optimal level of reactive power compensation can be chosen to achieve good compromise between the number of tap changes and losses in the line.
Can PV inverters and passive devices decentralized reactive power compensation?
The proposed decentralized reactive power compensation by PV inverters and passive devices was able to maintain voltage deviations within allowable limits and network losses were efficiently reduced. Presented research also disregards inverter losses.
What is reactive power compensation?
As per the proposed scheme, reactive power is injected to the grid through the PV inverter when the slope criteria of dPinv/dt is satisfied. When the value of dPinv/dt falls below kp, then reactive power compensation is provided. The level of reactive power compensation level varies with ks.
What happens if a solar PV plant is not accounted for properly?
If the reactive power requirement of the three winding transformers of a solar PV plant are not accounted for carefully, additional quantity of reactive power compensation devices may be required to meet the reactive power requirement of the plant, leading to additional cost being incurred.
