6 FAQs about [Distributed photovoltaic inverter voltage is high]

What are the problems with distributed photovoltaics?

With the large-scale access of distributed photovoltaics to the distribution network, its intermittent and random characteristics bring power quality problems such as voltage exceeding the upper limit, broadband oscillation, and three-phase unbalance to the distribution network.

Can PV inverters control reactive power output?

By using appropriate methods, PV inverters can autonomously regulate reactive power output in a distributed manner to improve voltage profile in networks.

Can PV inverters fold back power production under high voltage?

Program PV inverters to fold back power production under high voltage. This approach has been investigated in Japan, and though it can reduce voltage rise, it is undesirable because it requires the PV array to be operated off its MPP, thus decreasing PV system efficiency and energy production.

Can PV inverters improve voltage profiles?

Therefore, researchers have focused on the method of improving voltage profiles by regulating reactive power output of PV inverters [12, 13]. Traditionally, voltage control of distribution networks can be divided into three levels.

Can a PV inverter provide voltage regulation?

A PV inverter or the power conditioning systems of storage within a SEGIS could provide voltage regulation by sourcing or sinking reactive power. The literature search and utility engineer survey both indicated that this is a highly desirable feature for the SEGIS.

What happens if a distribution network is not connected to photovoltaics?

In the distribution network that is not connected to distributed photovoltaics, the voltage distribution is only affected by load fluctuations, and the voltage of the distribution line gradually decreases with the direction of the power flow.
