6 FAQs about [Photovoltaic storage microgrid on-grid and off-grid switching]

Can photovoltaic storage microgrid support system frequency and voltage without disconnecting?

To enable photovoltaic storage microgrid to support system frequency and voltage without disconnecting from power grid during power grid faults, an improved VSG low voltage ride through (LVRT) control strategy is proposed. Firstly, the transient characteristics of VSG are analyzed under short circuit fault.

What happens if a microgrid is off-grid?

When the microgrid is off-grid, due to the lack of the support of the large power supply system, a large frequency change is caused. Under the conventional control strategy, the maximum frequency is increased to 52.08 Hz, while under the control strategy with power feedback, the maximum frequency is only 51.7 Hz.

What is the maximum voltage fluctuation when microgrid is off-grid?

Comparing the node voltage changes when the microgrid is off-grid, the maximum voltage fluctuation of the conventional strategy is 0.517 kV. The effect of the control strategy proposed in this paper is significantly improved, and the maximum voltage fluctuation is only 0.253 kV. The same is true for the voltage when connected to the grid.

What is a novel control strategy for grid connected solar power plants?
