6 FAQs about [Solar power generation voltage loss protection]

Is voltage control a problem for solar PV integration?

Voltage control is one of the urgent issues in distribution systems for solar PV integration. Many LV networks have been designed decades ago, and are not well prepared to accommodate the large amount of power flowing through the grid. This paper describes the mechanism of the voltage rise issue, and the possible mitigation solutions.

How to mitigate voltage disturbances in a massive PV system?

To mitigate the voltage disturbances in a system with massive PVs integration, some techniques are devoted such as frequency regulation techniques, active power curtailment, reactive power injection (RPI), and storage energy. Also, with a high penetration level of distributed generators, the potential of dynamic grid support is discussed.

How to reduce power loss in PV inverters?

Certain methods are also proposed to decrease this power loss and the majority of them are based on central control or distributed methods that require communication among the PV inverters [39 - 46]. Although the communication-based methods are usually more efficient, the cost associated with them is usually high .

Can a low PV system cause overvoltage?

In residential feeders, in which the load consumption is relatively small during high PV generation periods, the potential for overvoltage is greater, and a lower share of PV systems may cause reverse power flow and an unacceptable voltage rise in the grid.

How to calculate solar energy loss?

Step 1: Import solar production and load scenarios by performing time series simulations, export the results on bus voltages, power losses, line flows, reactive power outputs from solar plants, at a given time resolution. Step 2: Find out the worst voltage value, and then calculate the accumulated energy loss over the simulation period.

Why do PV systems lose electricity during active power curtailment?

Firstly, the adoption of some of the voltage regulation techniques result in electricity losses. Moreover, in case of active power curtailment, electricity is lost as the power production of PV systems is reduced during times of curtailment. However, this only applies when curtailment is activated.
